Abstract

A pump unit (28) for a paint system (10) comprises a pump head (124); a pump body (126); and a pump plate (128), which are moulded components clamped together. A piston (100), including a diaphragm (134) retained between the pump body and plate, extends through a piston aperture (137) in the pump plate. An inlet valve and an outlet valve each comprise a valve seat (174,182) formed in the pump head and body respectively, and a flap (172,184) adapted to seal against the seat.
A pressure chamber (196) communicates with the outlet valve, and comprises a control actuator (104), including a diaphragm !194) retained between the pump body and plate, which actuator extends though a control aperture (202) in the pump plate selectively to enable and disable the pump in dependence on pressure in the pressure chamber, a pump outlet (102) communicating with the pressure chamber.
A dump/yield valve (122) releases excessive pressure in the pressure chamber. A switch button (30) operates the pump, the switch button serving to adjust spring bias (284) on the valve between a first high value in which the valve serves as a yield valve, and a second low value, where the valve serves as a dump valve.
