Abstract:
Water leakage and damage to the electric motor of a diaphragm type pressurized pump are avoided by providing the diaphragm with integral hollow cylinders which are inserted through ladder holes of piston head pushing chunks and deformed into sealing engagement with the pushing chunks and their corresponding wobble plates by screws extending through the cylinders and threadedly engaged within corresponding threaded holes of the wobble plates.
