Abstract
A multi-chamber wobble plate pump that includes a housing with an inlet port, an outlet port and a plurality of pump chambers. The pump includes inlet valves having an asymmetric cross-section with a thin section and/or a peripheral seal bead. A wobble plate is coupled to a diaphragm and a plurality of pistons. Rotation of the wobble plate moves the pistons within the pump chambers to draw in and force fluid out of the chambers. The diaphragm may have a thin cross-sectional area that creates a hinge. The pump may further have a pulsation damper and a flexible liner located in-line with an outward flow of fluid and which absorb pressure transients and reduce noise. The pulsation dampener may be integrated into the relief valve. An elastomeric sleeve may be located adjacent to the wobble plate to provide both a seal and a noise absorber.
