Abstract
A multi-chamber wobble plate pump having a housing with an inlet port, an outlet port and a plurality of pump chambers. 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 pump includes a plurality of inlet valves each located within one of the pump chambers to control fluid flow from the inlet port to the pump chambers. Each inlet valve has an asymmetric cross-section, a thin section and a stem along a longitudinal axis. The thin section of the valve has less mechanical strength than the remaining portion of the valve. The valve is configured to open first at the thin section from reduced pressure during outward movement of the piston allowing air to be removed from the chambers.
