Abstract
The invention relates to an improvement in internal combustion engine injection pump, according to which the injection timing is modified by moving the timing element (9) by means of a hydraulic actuator (41) fed with fuel which varies in pressure with the pump speed and which urges the actuator piston (42) against elastic means which react within an axially mobile rotating cylinder (47), of which the axial position is determined by contact between two cam surfaces (52,56) in series, and of which the rotation is a function of the position of the pump throughput control members.
