ABSTRACT:
Power paint sprayer includes a power handle assembly and a separately detachable pump and container assembly. The pump housing has a bail pivotally connected to opposite sides thereof for pivotal movement into and out of locking engagement with a detent on the top of the power handle assembly to detachably hold the pump housing up against the bottom of the power handle assembly. The pump housing may be cast in one piece and has a longitudinal bore extending therethrough in which a pump cylinder is permanently affixed using a suitable adhesive/sealant. The pump piston is driven by an oscillating armature whose movements are limited by a stroke limiting screw thus to limit the stroke of the pump piston. The stroke limiting screw threadedly engages a split nut held together by a pair of O-rings that apply a friction load on the stroke limiting screw to prevent creep thereof due to vibrations and the like. A slot may be provided in the bottom wall of the motor housing adjacent the back edge of the pump housing to prevent any liquid leakage from the pump from flowing down into the sprayer handle. Also, a safety guard having finger grips on opposite sides thereof may be attached to a nozzle nut threadedly connected to the outer end of the pump barrel to facilitate unscrewing of the nozzle nut by hand.
