Abstract

An airless sprayer utilizing a reciprocating piston pump ( 12 ) uses a block fluid manifold ( 16 ) attached directly to the pump cylinder ( 14 ) and which includes provisions for a pressure sensor ( 20 ), a dump or safety valve ( 18 ) and a hose outlet to minimize pressure drop which in turn maximizes spraying pressure as well as lessening the tendency to pack out.

Description

The direct articulation set pipe that is used for reciprocating piston pump
Technical field
The application number that the application requires on April 5th, 2002 to submit to is the preference of 60/369950 U. S. application.
Background technique
The airless sprayer of employing reciprocating piston pump is proved and generally is used for sprayed coating, coating and various web material.This sprayer typically adopts one to flow to the flexible pipe of long-range Manifolds from pumping cylinder, and this Manifolds comprises a dump valve and one and is used for pressure controlled pressure transducer.
Summary of the invention
Particularly, make that the pressure slippage minimum of (as spray gun) is favourable from the delivery side of pump to the spray-coating apparatus at the spraying web material and/or when adopting the very long flexible pipe of length.For this reason, the present invention adopts a block fluid manifold that directly is installed on the pumping cylinder, and this Manifolds comprises pressure transducer, dump valve or safety valve and flexible pipe outlet device.
From the following explanation of being done in conjunction with the accompanying drawings, these and other purpose of the present invention and advantage will seem more abundant, and identical reference mark is represented same or analogous part in the some of them accompanying drawing.
Brief description of drawings
Figure 1 shows that part exploded view of the present invention.
Figure 2 shows that erection drawing of the present invention.
Implement optimal mode of the present invention
As shown in the part exploded view of Fig. 1, the present invention represents with 10 that generally it is made up of a reciprocating piston pump 12 with pumping cylinder 14.Cylinder 14 is equipped with flat attachment face 14a, mounting hole 14b and the exit passageway 14c of output charging fluids in the pump 12.Fluid manifold 16 is preferably made by single piece of material such as stainless steel, and is fixed on the cylinder 14 by clamping bolt 22.By screw thread or other traditional mounting mechanism (known construction) safety valve/dump valve 18 and pressure transducer 20 are installed on the Manifolds 16.
What should be noted that is: can make various changes and modifications to this Manifolds-pump assembly, and not depart from as the following the spirit and scope of the present invention that claim limited.

Claims (2)

1. reciprocating piston pump, it has pumping cylinder, Manifolds and pressure transducer, improves to comprise described Manifolds directly is installed on the described cylinder, thereby makes pressure descend minimum and increase jet pressure.
2. reciprocating piston pump as claimed in claim 1, wherein said pressure transducer is installed on the described Manifolds.
