Definitions
- Airless sprayers which utilize reciprocating piston pumps have proven popular for applying paints, coatings and various texture materials. Such sprayers have typically utilized a hose running from the pump cylinder to a remote manifold which incorporates a dump valve and a pressure sensor for pressure control.
- the instant invention uses a block fluid manifold attached directly to the pump cylinder and which includes provisions for a pressure sensor, a dump or safety valve and a hose outlet.
- Figure 1 shows the instant invention in a partially exploded view.
- Figure 2 shows the instant invention in an assembled view.
- the instant invention is shown partially exploded in Figure 1, is comprised of a reciprocating piston pump 12 having a pump cylinder 14. Cylinder 14 is provided with a flat mounting surface 14a, attachment holes 14b and outlet passage 14c which outputs the pressurized fluid from within pump 12. Fluid manifold 16 is desirably formed from a single block of material such as stainless steel and is fastened to cylinder 14 by fastener bolts 22. A safety valve/dump valve 18 (of known construction) and pressure sensor 20 are attached via threading or other conventional attachment mechanisms to manifold 16.
