ABSTRACT:
Positive displacement type oil pump for two cycle engines, which is variable in displacement. The pump is provided with a pressure responsive diaphragm which is used to control the pump displacement. The diaphragm is subjected to the engine exhaust gas pressure so that the pump displacement is controlled in response to a change in the engine speed as well as to a change in the engine throttle valve opening.
