Beschreibung
Zusammenfassung:	A hydraulic circuit is disclosed. The hydraulic circuit includes an actuating mechanism having an engine valve and an engine valve spring, an added motion valve system having a cam system, a valve in fluid communication with the actuator mechanism, and a dump valve and at least one check valve in fluid communication with the valve to allow a recovery of energy stored in an engine valve spring during closing movement of the engine valve associated with the added motion system. A method for controlling a hydraulic circuit is also disclosed.
