    摘要： An engine valve actuation system is provided. An intake valve 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 connected 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 control valve is disposed between the source of fluid and the directional control valve. The control valve is moveable between a first position to prevent the flow of fluid between the source of fluid and the directional control valve and a second position to allow the flow of fluid from the source of fluid to the directional control valve.

    摘要： 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.

    摘要： An engine valve actuator is provided. The actuator includes an actuator housing that defines a tank adapted to store a supply of fluid and a bore in fluid communication with the tank. A piston is slidably disposed in the bore of the actuator housing. The piston is adapted to move between a first position and a second position where the piston selectively engages an engine valve. A mechanical biasing element acts on the piston to move the piston towards the second position. A control valve is disposed between the tank and the bore in the actuator housing. The control valve is moveable between a first position where fluid is allowed to flow between the tank and the bore and a second position where fluid is prevented from flowing between the bore and the tank to trap fluid in the bore. The trapped fluid prevents the piston from moving with respect to the actuator housing to thereby prevent the engine valve from moving to a closed position.

    摘要翻译： 提供发动机气门执行器。 致动器包括致动器壳体，其限定适于存储流体供应的罐和与罐流体连通的孔。 活塞可滑动地设置在致动器壳体的孔中。 活塞适于在第一位置和第二位置之间移动，其中活塞选择性地接合发动机气门。 机械偏置元件作用在活塞上以使活塞朝向第二位置移动。 控制阀设置在油箱和致动器壳体中的孔之间。 所述控制阀可在第一位置和第二位置之间移动，所述第一位置允许流体在所述罐和所述孔之间流动，以及阻止流体在所述孔和所述罐之间流动以将流体捕获在所述孔中的第二位置。 被捕获的流体防止活塞相对于致动器壳体移动，从而防止发动机气门移动到关闭位置。
