Beschreibung
Zusammenfassung:	An engine valve actuation system is provided. The engine valve actuation system includes an intake valve that is moveable between a first position to prevent a flow of fluid and a second position to allow a flow of fluid. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator is configured to selectively prevent the intake valve from moving to the first position. A source of fluid is in fluid communication with the fluid actuator. A directional control valve is configured to control a flow of fluid between the source of fluid and the fluid actuator. A fluid passageway connects the directional control valve with the fluid actuator. An accumulator is in fluid communication with the fluid passageway. A restricted orifice is disposed between the accumulator and the fluid passageway to restrict a flow of fluid between the accumulator and the fluid passageway.
