An electronically controllable hydraulically powered asymmetrical valve actuating mechanism for use in an internal combustion engine of the type having engine intake and exhaust valves with elongated valve stems is disclosed. The actuator is a bistable electronically controlled hydraulically powered transducer having an armature including a power piston which is reciprocable between first and second positions along with a hydraulic arrangement for powering the armature from a first (engine valve closed) position to a second position. A bistable control v...
An asymmetrical bistable hydraulically powered actuator mechanism reciprocable between each of two stable positions and comprising: a replenishable source of high pressure hydraulic fluid, a power piston having a pair of opposed faces and positioned closely adjacent the source of high pressure fluid, and a control valve for selectively supplying high pressure fluid to one of the power piston faces thereby causing translation of a portion of the mechanism which includes the power piston in one direction; resilient means which is compressed during translat...
