Abstract: A texture spray gun having an air passageway (29) and a texture material passageway (28) in a handle (14) of the gun do) and a selectively removable screw to convert the gun from a non-air bleed configuration to an air bleed configuration and an improved air valve (22) providing a minimum air flow regardless of the setting of the air valve (22), preventing texture material from clogging an air path at the outlet of the gun.

Abstract: A texture spray pump unit (100) having a tank (140) with an outlet for providing texture material to a pump (120), for delivery to a texture spray gun. The spray pump unit (100) also has an air source (180) for providing power to the pump (120) and air to deliver the texture material from the gun. A frame supports the tank (140), air source (180) and pump (120). The tank (140) is removable from the frame, and has a self closing valve to block leakage from the tank (140) when removed from the frame. The valve may have a pair of helper springs urging the valve closed. Mating portions on the frame and tank (140) guide engagement of a tank outlet with a pump inlet tube.

Abstract: Paint spraying equipment having an electric motor, gear reducer and fluid section for pressurizing paint and a pressure control module utilizing a combined fluid manifold and pressure control component mounting frame formed of a single die casting and including an access port for servicing a pressure transducer and further including a paint relief aperture in the cover for directing leakage of paint to the exterior of the assembly.

Abstract: An improved fluid section for piston type paint pumps having the piston made from unplated stainless steel and wherein the seal is a multiple lip type formed of ultra-high molecular weight polyethylene and the seal further includes one or more U-shaped internal stainless steel springs.

Abstract: A planocentric drive mechanism is disclosed which includes a plurality of longitudinally extending pins arranged in a circle about an axis of rotation, a rotating shaft which carries an eccentric cam, and a pinion gear which is rotatably carried by the eccentric cam. The pinion gear has a plurality of apertures formed therethrough, within which the pins are disposed, thereby limiting the pinion gear to oscillation. An output shaft is aligned with and rotatably about the axis of rotation, and includes a plurality of second pins which mesh with cycloidal teeth disposed about the periphery of the pinion gear.
