Abstract
Variable displacement type lubricating oil pump for two cycle engines having a displacement control element which is rotated in response to the engine throttle valve position. The control element has a cam which is so shaped that the pump displacement is changed in accordance with the engine throttle valve position. When the control element is accidentally disconnected from the engine throttle valve control device, the control element can be rotated beyond the minimum displacement position which corresponds to the engine idling position, whereby the pump displacement is increased than in the idling position.
