ABSTRACT:
A hydraulic automatic device for the injection advance of a diesel engine. The device includes 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, the position of which is a function of the speed of rotation of the device, 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.
