ABSTRACT:
The invention concerns a hydraulic automatic device for the injection advance of a diesel engine. The device comprises a hub fixed to the pump camshaft and a casing fixed to the drive pinion of the pump. Two rollers in the casing bear on the ramps of pistons of which the position is a function of the speed of rotation, owing to two inertia blocks, the thrust of the pistons and the control of the slide valve of a hydraulic distributor. Thus, at each speed of rotation, there corresponds a certain angular displacement of the components and a certain advance of the injections.
