ABSTRACT:
A diaphragm pump with mechanical return stroke assist. The pump includes a flexible diaphragm within a pump housing which is driven by a pressurized fluid during a power stroke and returned to an initial position during a return stroke. The mechanical assist includes a spring and metal rod attached to the diaphragm. During the power stroke the spring stretches and stores potential energy that is released as the tensioned spring and tension rod pull the diaphragm back to an initial position during the return stroke.
