Abstract (en)
[origin: EP0255668A2] 1. A device for the hydraulic control of reciprocating valves on piston engines where the opening movement s transmitted through a hydraulic chamber (3) and a working piston (4) directly to the valve (7) and the closing movement is triggered by a force-storage element (22) acting upon the valve (7), while for the fluid then displaced by the working piston (4) a damping gap (19) which is formed by the working piston (4) and a non-displaceable wall (15) of the hydraulic chamber (3) is provided, characterised in that the working piston (4) is provided with a blind hole in which there is guided a brake element (8) supported through a force-storage means (9) on the working piston (4) and displaceable in the direction of movement of the working piston which brake element forms one of the surfaces of the damping gap.
