Description

The invention relates to a compressed gas shot device (impulse firing device) for firing of one-piece, filled or connected by an aid Geschosskörpem using an expanding compressed gas, preferably Drudduft.

• Einbringen von Stoffen an exponierte, schwer zugängliche oder die Sicherheit von Personen gefährdende Stellen oder Orte (Brandbekämpfung, Lawinenauslösung etc.)
• Verschießen vön Hilfs- und Rettungsleinen, Erste Hilfe-Päckchen etc.
• Einbringen von Mitteln zum Personen- oder Objektschutz (Tränengas, Kampfmittel etc.).

Shot devices of various designs are well known, and for different uses mostly different methods for accelerating the projectile body and suitable devices used for this purpose. Areas of application are as examples:

• Introduction of substances to exposed, hard-to-reach places or places endangering the safety of persons (firefighting, avalanche release, etc.)
• Shooting of aid and rescue lines, first aid packages etc.
• Introduction of means for personal or property protection (tear gas, ordnance etc.).

As projectile body come both solid material (plastic, rubber, metals, etc.) and hollow body (with different, depending on the application with solid, liquid or gaseous fillings) in question. Furthermore, special devices (lifelines, auxiliary lines, etc.) can be connected to a projectile body as a carrier. Depending on the task, the projectiles can have different sizes, weights, shapes or material compositions.

For example, DE 2 227 114 A discloses a game shooting machine with a ball race which can be connected to a compressed gas source and an additional ball race Cartridge blind run, which is connected via a gas passage to the loading end of the ball run, so that a cartridge blind run cartridge (blank cartridge) forms the source of compressed gas for the ball race, which then shoots a ball located at the end of the ball run through the ball race. This results in a moderate, but sufficient for the purpose of the game acceleration of the ball.

From US Pat. No. 3,369,609 A, a pressurized gas firing device for fire-fighting grenades is known, consisting of a projectile barrel and a pressurized gas casing. The compressed gas housing is divided by a stationary partition into two chambers. A guided through this partition valve rod arranged at its ends valves closes in the initial position in which both chambers are filled with compressed gas, with the front valve in the front chamber, the bullet barrel opening and the rear valve in the rear chamber open to the atmosphere valve opening. Both valves are in equilibrium with each other via the pressure of the compressed gas and the valve rod connecting them, so that both valves are pressed firmly against their valve openings. To fire this pressurized gas shot device, the pressurized gas is discharged from the rear chamber into the atmosphere, thereby changing the equilibrium such that the valve stem opens the front valve and the gas pressure in the front chamber drives the grenade through the projectile barrel. A disadvantage of this known compressed gas shot device is in particular the very complicated and complicated structure.

A pressurized gas gun capable of firing, for example, harpoons or the like is known from US Pat. No. 2,581,758. It consists of a projectile barrel with a compressed gas housing, which is also divided by a stationary partition into two chambers. In the rear chamber, the working chamber, a displaceable piston is arranged, whose piston rod passed through the partition and in the front chamber, the Compressed gas chamber, a valve cap pressed against the open end of the bullet barrel, wherein in the compressed gas chamber introduced compressed gas and the rear side of the piston supporting the compression spring provide sufficient contact pressure. To fire this compressed gas shot device pressurized gas is introduced via a line in the working chamber, whereby the piston is displaced and opened by the connecting piston rod, the front valve and the harpoon is fired by the existing compressed gas.

There are also methods and devices for the local destruction of compact materials, such as slag approaches, masonry residues, etc. in hot thermal systems such as heat exchangers, industrial furnaces, firing systems, metallurgical melting vessels known to work using a disintegrating means, which is arranged at the front end of a lance and brought by holding and moving the rear end of the lance through an opening of the hot thermal plant in the immediate vicinity of the material to be destroyed and ignited by means of an igniter at an arbitrary time. However, such devices are not suitable for applications in larger distances from the compact materials.

In view of these aspects, it is an object of the invention to provide a pressurized gas shot device which can be used universally in a simple and lightweight design for the various application areas listed. In particular, the cleaning of dirt, encrustations, caking, coverings, etc. as well as the elimination of disturbances in the flow of material (blockages, loosening) of bulk materials should be made possible. In addition, the handling should be particularly simple and inexpensive.

• b) the compressed gas chamber (11) for compressed gas supply has a designed as a check valve inlet valve (14) and with the working chamber (12) via a control valve (15) is connected.

Advantageous embodiments of the invention are specified in the subclaims.

• Gespeichertes Druckgas verschließt in der Ausgangsstellung die hintere Querschnittsfläche des mit einem Geschosskörper geladenen Geschosslaufs mit einer Ventilplatte.
• Bei Auslösung des Schussvorgangs wird diese Ventilplatte durch das gleiche Druckgas geöffnet.
• Das Druckgas expandiert im vollständig freigelegten Querschnitt des Geschosslaufs hinter dem Geschosskörper und schießt dabei den Geschosskörper aus dem Geschosslauf.

The operation of the compressed gas gun according to the invention is based on the following process features:

• Stored compressed gas closes in the initial position, the rear cross-sectional area of the charged with a projectile body projectile barrel with a valve plate.
• When the firing process is triggered, this valve plate is opened by the same compressed gas.
• The compressed gas expands in the fully exposed cross section of the bullet barrel behind the projectile body and thereby shoots the projectile body from the bullet barrel.

For the possible sequence of these successive steps, the individual components of the simple in its construction pressurized gas shot device are in the following operative connection:

In the starting position or ready to fire located in the pressure gas chamber is a stored pressure gas of about 5 to 10 bar, which was eigefüllt via an inlet valve in the pressure gas chamber, for example by connection to a replaceable gas cartridge or a gas cylinder or a compressed gas line to a continuously working pressure gas generator.

The gas outlet opening of the pressure gas chamber to the projectile barrel is closed by the valve plate connected to the piston rod, wherein the closure is maintained by the pressure gas pressed on one side of the pressure gas chamber against the valve plate. In the separated by the partition wall of the pressure gas chamber working chamber is no pressurized gas, except for small leaks that may leak through the piston rod guide through the partition from the pressure gas chamber.

The bullet barrel is located in front of the valve plate of the projectile to be fired. For firing the shot, the control valve connecting the pressure gas chamber to the working chamber is opened. For this opening to take place without delay and abruptly, the control valve is servo-supported according to an advantageous embodiment of the invention. Through the now open control valve, the compressed gas flows from the pressure gas chamber into the working chamber, which leads to a pressure equalization in both chambers, d. H. also on the back wall of the working chamber formed from the movable working piston now acts the same pressure as on the valve plate, but in the opposite direction.

Since the effective cross-sectional area of the valve plate is smaller than that of the working piston, the force acting on the working piston by the pressure gas is greater than the force exerted on the valve plate by the pressurized gas. By virtue of this differential force acting in the direction of the working piston, the working piston thus shifts in the direction opposite to the dividing wall, whereby the valve plate connected to the working piston via the piston rod shifts in the same direction and thus opens the closure of the projectile barrel. The pressure gas present in the pressure gas chamber can now expand into the bullet run which is open to the rear and with high pulse energy shoots out the projectile body located in the bullet barrel to the front. To achieve the best possible energy conversion is here the valve plate is formed only slightly larger than the projectile body cross-section and the projectile barrel cross-sectional area.

After complete expansion of the compressed gas, the piston rod is pressed by a spring element, which is supported in the pressure gas chamber on the partition back to its original position, whereby the valve plate is pressed back into the closed position on the rear end of the bullet barrel. Reloading the projectile barrel with a new bullet and filling the compressed gas chamber with "fresh" compressed gas is now possible again.

The loading of the bullet barrel can be done individually manually over the bullet or semiautomatic (for several floors) according to an embodiment of the invention via a magazine device which is arranged in the region of the rear end of the bullet barrel.

In order to simplify in particular the charging process of complicated projectile body, according to a further embodiment of the invention, the projectile barrel is releasably connected to the compressed gas housing, for example via a bayonet connection, whereby the rear end of the projectile barrel is accessible in a simple manner. Alternatively, however, the projectile body can also be introduced from the front into the projectile barrel.

In order to bring the projectile body with the required accuracy in the mentioned different areas of application to the target, the compressed gas shot device according to the invention is provided with a target device. This can be, for example, a simple mechanical aiming device (auxiliary reticule) or optionally an adjustable (laser) aiming device. It is expedient to mount the compressed gas gun on a tripod, which is possible because of their low weight without any problems.

the compressed gas shot device of Fig. 1 in the shooting position.

In FIGS. 1 and 2, the pressurized gas shot device 1 essentially consists of two interconnected components, the projectile barrel 2 and the compressed gas housing 5. The compressed gas housing 5 is at its front end - In the drawing left - limited by the projectile barrel 2 and at the opposite end by a rear wall 17. Within the compressed gas housing 5 is a stationary partition 10 which divides the compressed gas housing 5 into a pressure gas chamber 11 and a working chamber 12. Through this partition 10, the piston rod 6 of a working piston 7 is guided. At the end located in the pressure gas chamber 11 (in the drawing at the left end), a valve plate 8 is arranged on the piston rod 6, which closes the projectile barrel 2 which opens into the pressure gas chamber 11. Within the pressure gas chamber 11, the piston rod 6 is connected to a spring element 9 which is supported on the partition wall 10 and presses the valve plate 8 firmly against the rear part of the projectile barrel 2 via the piston rod 6 and thus closes the expansion space 4 to the projectile body 3.

At the other end of the piston rod 6, which is located in the working chamber 12, the working piston 7 is arranged and dimensioned so that it sealingly forms the rear wall of the working chamber 12. By the displaced by the spring element 9 to the projectile barrel 2 toward the piston rod 6, the working piston 7 is in the vicinity of the partition 10, so that the working chamber formed between the partition 10 and the working piston 7 12 small and a remaining dead space 13 between the piston 7 and the rear wall 17 is large. On the housing rear wall 17 are gas outlet holes 16 to allow for the axial displacement of the working piston 7 within the dead space 13, a pressure compensation.

The compressed gas chamber 11 and the working chamber 12 are connected to each other in the immediate vicinity of the partition wall 10 via a control valve 15. In the illustrated starting position of the compressed gas gun 1 according to FIG. 1, this control valve 15 is closed.

In the front region of the compressed gas chamber 11, an inlet valve 14 designed as a check valve is arranged on the compressed gas housing 5 for connection to a compressed gas generator or compressed gas tank. The filled via this inlet valve 14 into the pressure gas chamber 11 compressed gas 20 then presses together with the spring element 9, the valve plate 8 firmly against the rear opening of the projectile barrel 2. The compressed gas gun 1 is ready to fire, as soon as the compressed gas chamber 11 with compressed gas 20 from about 5 to 10 bar is filled.

In Figure 2, the pressurized gas gun 1 is shown during the triggering of the shot. By opening the control valve 15, a partial amount of the compressed gas 20 flows from the pressure gas chamber 11 into the working chamber 12 and there against the working piston 7, which is due to its opposite the valve plate 8 larger area under magnification of the working chamber 12 (in the drawing to the right ) moves axially. Furthermore, the piston element 6 and the valve plate 8 are displaced in the same direction. Furthermore, the spring element 9 is compressed by this displacement and the dead space 13 is reduced, the air 18 present in this dead space being forced outward via the gas outlet bores 16.

By caused by the piston 7 displacement of the valve plate 8, the entire free cross-sectional area is suddenly exposed at the rear of the projectile barrel 2 and the compressed gas 20 expands in time-minimized complete relaxation in the behind the projectile body 3 is formed and constantly increasing expansion space 4 and presses the projectile body 3 recoilless from the projectile barrel 2 forward in the direction of arrow 19 out.

After the firing, the control valve 15 is closed and the inlet valve 14 for the re-automatic or semi-automatic loading with one or more projectile bodies 3 for pressurizing and producing the shot readiness opened.

The inventive measures and embodiments are not limited to the embodiment shown in the drawing figures. Possible modifications of the device according to the invention may be that, for example, the valves and / or the spring element are designed and arranged differently. Also, the compressed gas housing may have different cross-sectional shapes. Likewise, the internal design of the compressed gas housing, the use of any materials and the respective structural design in adaptation to particular uses of the skilled person.
