Abstract
This invention relates to a hydraulic adjustment arrangement for the control of the injection start for a motor vehicle internal combustion engine, consisting of a primary part on the side of the internal-combustion engine and a secondary part on the side of the injection pump as well as radial pistons operating as a function of the admission of hydraulic oil, said radial pistons operating as a function of the admission of hydraulic oil, said radial pistons being guided in cylinders contained in the secondary part and interacting with levers extending in a circumferential direction and being pivoted on the secondary side, flexible connectors resting on said levers in one portion and fixed to the primary part on another portion, such that a radial movement of the pistons and as corresponding outward swivel movement of the levers and the flexible connectors causes a rotation of the secondary part relative to the primary part. A low-pressure hydraulic system is sufficient for the operation of the hydraulic adjusting device because the movement of the radial pistons is also supported by the centrifugal forces occurring with increasing speed of the internal-combustion engine.
