Abstract (en)
[origin: EP0254967A2] 1. A device for hydraulic control of reciprocating valves on piston engines, the opening movement being transmitted directly to the valve via a hydraulic chamber and a working piston and the closing movement being triggered by an energy accumulating element engaging the valve, a throttle gap formed by the working piston and a stationary wall of the hydraulic chamber being provided for the fluid displaced in the process by the working cylinder, characterised in that a freely-movable orifice plate (13) is provided in the hydraulic chamber (3) between an abutment (23) and a stationary abutment (15) on the casing, and divides the throttle gap into a first damping gap (19) formed by the orifice plate (13) and the working piston (4), and a second damping gap (20) formed by the orifice plate (13) and the abutment (15) on the casing.
