| description | A diaphragm pump having an improved wobble plate and cam/bearing assembly for increased pump life and improved inlet and outlet valve design for increased effective sealing area. A cam/bearing assembly includes a cam injection molded directly into an inner race of a bearing to prevent the cam from pulling away from the bearing. The wobble plate is injection molded directly onto an outer race of the bearing to prevent the wobble plate from pulling away from the cam and bearing. Inlet and outlet check valves include rounded peripheral relief zones that form a band, as opposed to a line, of effective sealing area when in the sealed position within a valve seat that eliminate or reduce sealing inconsistencies and increase sealing efficiencies. |
