Abstract: A piston pump assembly with a rotatingly driven swashplate in driving relationship with a rocker arm and piston engaged with one end of the rocker arm. A spring urges the rocker arm and piston into contact with an annular ring carried by a bearing in the swashplate. The spring may be a separate leaf spring or may be formed integrally with the rocker arm. The rocker arm engagement with the piston uses a spherical ball-joint-like surface. The contact between each of the rocker arm and piston and the annular ring utilize spherical surfaces on the rocker arm and piston, with an elongated footprint on the rocker arm and a circular footprint on the piston. The piston is allowed a slight radial play in operation.

Abstract: An improved cooling arrangement for an electric motor in a pump assembly, including a resilient fan baffle having a planar main surface and a pair of wings extending perpendicularly out from the main surface to direct airflow away from the motor when the fan baffle is installed on the motor. A method of installing the fan baffle includes bending two ends of the periphery of the fan baffle to clear obstructions on the motor, and then releasing the ends to allow them to come together in a planar arrangement.

Abstract: A diaphragm pump for pumping a fluid, such as paint, includes a diaphragm separating a first chamber for accommodating and dispensing the paint from a second chamber for accommodating a drive fluid, and a piston that reciprocates to drive the drive fluid within the second chamber in order to flex the diaphragm to provide the pumping action within the first chamber. The diaphragm pump also includes a backing ring mounted adjacent the diaphragm that is configured to distribute the drive fluid across the diaphragm to cause a flexible region of the diaphragm to flex toward the first chamber from the outer perimeter inward toward a central pumping surface in a rolling manner. This diaphragm movement results in substantially all of the paint adjacent the diaphragm within the first chamber to move out of the first chamber when the diaphragm reaches its travel limit, and thus improves the efficiency of the diaphragm pump.

Abstract: A pressure relief assembly for use with a paint pump having a chamber with a pressure relief port located immediately adjacent an inlet port of the pump. The pressure relief assembly includes a mounting member, inlet washer, rupture pad and outlet washer. The mounting member is threaded on its exterior surface and includes an inlet end, an outlet end, and a relief passage extending between the inlet and outlet ends. A rupture recess in the inlet end is sized to receive the inlet washer, rupture pad and outlet washer, with the rupture pad positioned between the washers. The inner diameter surface of the outlet washer is convex. The pressure relief assembly is screwed into the pump with the inlet end adjacent to the pressure relief port. The rupture pad forms a seal between the pump chamber and atmosphere that ruptures to vent the chamber when the pressure within the chamber exceeds a predetermined rupture pressure.
