Variable pump for internal combustion engine mechanical fuel injection system has element whose displacement in negative direction is limited as function of movable stop element position

摘要

The pump has a pump body (50), two displaceable elements (58, 60) mounted in the pump body and movable depending on an actuating force, a shaft rotatably supported near the shaft, an eccentric bearing mounted on the shaft and connected to the first displaceable element to deliver the actuating force based on the shaft rotation, an adjustable stop element (84) movable wrt. the second displaceable element, whereby the displacement of the second element in a negative direction (71) is limited as a function of the position of he stop element.. An Independent claim is also included for a method of pumping fuel into an internal combustion engine.
