ABSTRACT:
An improved diaphragm pump in which the diaphragm has a majority of its area available for flexure and deformation thereby allowing for a variable stroke length on the diaphragm pump and decreased wear of the diaphragm in operation. Additionally such a flexible diaphragm is additionally deformed by the pressure of the fluid in the pumping chamber thereby forming a "piston" of the diaphragm as it is deformed over the deforming piston of the pump.
