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 further 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. The pump also includes a plurality of outlet valves that control fluid flow from the pump chambers to the outlet port. A wobble plate is coupled to a diaphragm and a plurality of pistons. The diaphragm has at least one flex area with a leading edge and a trailing edge. The diaphragm has a plurality of diaphragm piston openings each with a diaphragm piston opening centerline. The wobble plate has a plurality of wobble plate piston openings, each wobble plate piston opening having a wobble plate piston open centerline that is offset from one of diaphragm piston opening centerlines.
