Description

[Detailed description of the invention] This invention relates to a device that adjusts the adjusting part of a carburetor by moving a part of the taper or a screw, such as a metering screw, a pilot screw, an air screw, or a throttle stop screw, etc., and is arbitrary. The object of the present invention is to provide a device of this kind that can be adjusted at intervals of 1 to 2 and in any direction.

Recently, with the diversification of automobile engine equipment, it is necessary to install many items in a complicated and narrow space, and the adjustment positions and adjustment methods of each adjustment part of the carburetor are becoming limited.

However, adjustment of the metering screw, pilot screw, air screw, or throttle stop screw that adjusts the flow rate of fuel, air, etc. is often limited to a certain position due to the structure or performance of the carburetor, and it is inevitably necessary to adjust it manually. There are inconveniences such as not being able to reach the ball or not being able to use a screwdriver. Therefore, it is necessary to connect the ball with a flexible pipe or to put the ball in a bent pipe so that it can be operated from any remote location. Get in,
Various proposals have been made to transmit operating force using this method, but the flexible pipes described above have drawbacks such as difficulty in fine adjustment and the latter being expensive.

The present invention was developed in view of the above points, and the adjustment screw is divided into two parts, and a close coil spring is installed between the tip part and the waggi drive part, and this is installed inside a rigid pipe that is bent as necessary. The insertion tip is connected to the carburetor and the other end is provided with a screw drive part.

This tightly coiled spring is an operating force transmitting part, and is a tension coil spring with an initial tension, with the hook part removed.

An example of the present invention applied to a throttle stop screw as shown in the drawings is as follows: 1 is the main body of a carburetor, 2 is a throttle valve, 3 is a throttle lever, 4 is a return spring, and 5 is a throttle operation cable. , 6 is an adjuster, 7 is a mounting boss of the adjustment device,
8 is a tightly wound spring, 9 is a rigid pipe, 10 is a spring for removing backlash, 11 is a knob for adjusting the idling opening of the throttle valve, 12 is the tip end shaft of the knob,
Reference numeral 13 indicates the carburetor main body, a fixed bracket in addition to the carburetor body, and reference numeral 14 indicates a mounting boss for the knob.

The operation will be explained based on the above structure. The adjuster 6 comes into contact with the throttle lever 3 to which a returning force is applied, and the idling of the engine is adjusted by moving the adjuster 6 back and forth.

The adjuster 6 is slidably fitted into a mounting boss 7 screwed into a part of the carburetor main body, and a backlash removing spring 1 is installed.
0, it is pressed in the same direction as the return force of the throttle valve.

A tightly wound spring 8 is in contact with the other end of the adjuster 6.

This spring 8 is fitted into a rigid pipe 9 connected to the mounting boss 7, with a small fitting gap.

This rigid pipe 9 is screwed into and supported by a mounting boss 14 attached to a fixed bracket 13 in addition to the carburetor body, which is bent in such a way as to keep the inner diameter at a position where the carburetor can be easily adjusted.

One end of the spring 8 is the adjuster 6, and the other end is the adjustment knob 1.
It is in contact with the tip shaft portion 12 of No. 1.

In this case, the role of the spring 10 for removing backlash is that when the rigid pipe is shaped in the required direction, the spring is biased to one side within the pipe due to the fitting clearance and longitudinal clearance between the rigid pipe 9 and the closely wound spring 8. Even when the adjustment knob 11 is turned, the adjuster 6 may not move against the return force of the throttle lever 3. To prevent this, when the adjustment knob 11 is moved, the rigid pipe 8 is By smoothly moving the contact spring along the wall surface, the movement of the knob 11 is immediately transmitted to the movement of the adjuster 6, making fine adjustment possible.

As described above, according to the present invention, the adjustment knob can be placed at any position, which is extremely advantageous in terms of dovetail control, and fine adjustment is possible because it utilizes the longitudinal movement of the close coil spring. Moreover, it has various effects such as low cost.
