Abstract

This invention relates to a device and method for varying the timing of fuel injection for a combustion engine. The device comprises a housing (1) within which two shafts (2, 3) are coaxially arranged and torsionally conjoined by means of splines (6, 7) and a force-transmitting member (5). When the force-transmitting member (5) is displaced, which is partially achieved by means of a hydraulic fluid within the housing, the angular positions of the shafts (2, 3) will be readjusted. Furthermore, the housing (1) contains a revolution sensing device (83, 84) which is movable in a radial direction within a recess (24) which communicate with a pressurized hydraulic fluid. The revolution sensing device (83, 84) controls the flow fhrough the recess (24) in dependence on the number of revolutions. The method deals with the varying of the timing of fuel injection at three different intervals of rotational speed.
