Abstract (en)
[origin: US4708114A] A fuel injection pump for internal combustion engines is proposed, in which for normal engine operation the control of the injection quantity and of the beginning and end of supply for injection is effected by means of a control slide which is axially displaceable on the pump piston and in which a radial bore (connecting conduit) controlled by the pump piston is present in the pump cylinder, with which radial bore the pump work chamber can be made to communicate with the suction chamber of the pump. The latest end of supply for the injection is determined in that after a predetermined stroke of the pump piston a relief conduit is arranged to coincide with the radial bore and thereby relieve the pump work chamber. Because the radial bore is only blocked after a pre-stroke has been executed by the pump piston the earliest supply onset also can be controlled with this bore as well.
