摘要： A valve actuator assembly for an engine includes a movable engine valve and a movable spool valve. The valve actuator assembly also includes a driving channel interconnecting the spool valve and the engine valve and a feedback channel interconnecting the spool valve and the engine valve. The valve actuator assembly includes an actuator operatively cooperating with the spool valve to position the spool valve to prevent and allow fluid flow in and out of the driving channel to position the engine valve. The valve actuator assembly further includes an on/off valve in fluid communication with the feedback channel to enable and disable the feedback channel to control motion of the spool valve.

摘要： A hydraulic manifold assembly for variable actuation of engine valves in accordance with the invention includes oil flow galleries. Engine oil under pressure communicates with a global supply gallery in the manifold assembly, from which pressurized oil is supplied selectively via individual supply galleries to each variable actuator for each valve through the action of solenoid valves. At engine startup, all galleries may be empty of oil, or partially filled. A global relief valve at the end of the global supply gallery causes air to be purged immediately upon startup of the engine. Each solenoid and individual gallery is provided with a low pressure relief valve leading back to the crankcase when the solenoid supply valve is closed. A bleed orifice between the global supply gallery and each individual gallery continually bleeds oil under low pressure into the individual gallery, which purges initial air therein. Anti-draining means in each individual gallery keeps the gallery filled when the valve deactivation mechanism is deactuated.

摘要： An apparatus for controlling gas exchange valves of an internal combustion engine is disclosed, which have hydraulic valve actuators (11) each assigned to one gas exchange valve, with one adjusting piston (13) acting on the gas exchange valve and two hydraulic work chambers (121, 122) defined by the adjusting piston (13), of which chambers the first work chamber (121), acting on the gas exchange valve (10) in the closing direction, is constantly filled with fluid that is under pressure, and the second work chamber (122), acting on the gas exchange valve (10) in the opening direction, can be filled with and relieved of fluid that is under pressure in alternation via a first and second electrical control valve (24, 25; 26, 27). To reduce the cost, the second control valves, which are preferably combined into a valve unit (40), for one pair of valve actuators (11), which actuate two gas exchange valves used as inlet or outlet valves of a combustion cylinder, are triggered by a common electrical control signal

摘要： An hydraulically controlled actuator (16) for activating a valve (10) is proposed, especially for activating a gas-exchange valve (10) in a combustion cylinder (11) of an internal combustion engine, which includes two fluid-filled pressure chambers (21, 22) having controllable chamber volumes and a movable operating piston (18) which delimits the pressure chambers (21, 22) by piston sides facing away from one another, the operating piston (18) acting upon the valve (10) and having an effective closing area acted upon by fluid pressure in the pressure chambers (21, 22) to close the valve (10) and an effective opening area acted upon by the fluid pressure to open the valve (10). To influence the kinematics of the opening and closing movement of the valve (10), the operating piston (18) is designed such that the surface area of at least one of the two effective areas changes along the sliding path of the operating piston (18).

摘要： A gas exchange valve device (10) for an internal combustion engine (12), in particular of a motor vehicle, is provided with a hydraulic apparatus (15). This hydraulic apparatus (15) includes a fluid circuit (38, 42, 46, 54) and at least one pressure reservoir (62, 72) connected to the fluid circuit (38, 42,46, 54) and containing a piston (66, 76) prestressed by a device (68, 84), and also includes a controllable actuating device (16). A gas exchange valve (12) is also provided, whose valve element (26) is acted on by the actuating device (16). In order to achieve a simpler design of the gas exchange valve device (10), the invention proposes that the pressure reservoir (72) be disposed so that in an approximately unpressurized state of the pressure reservoir (72), its piston (76) at least indirectly locks the valve element (26) of the gas exchange valve (12) in an essentially closed position.

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 check valve is disposed between the directional control valve and the source of fluid, only allowing fluid flow from the fluid source to the directional control valve. A bleed orifice may be disposed between the directional control valve and the source of fluid, in parallel with the check valve.

摘要： An engine valve actuation system is provided. An intake valve is moveable between a first position where the intake valve prevents a flow of fluid relative to the intake valve and a second position where the intake valve allows a flow of fluid relative to the intake valve. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator having a chamber is adapted to selectively prevent the intake valve from moving to the first position. A fluid supply system is adapted to deliver fluid to the chamber of the fluid actuator. A pressure sensor is operatively engaged with the fluid supply system and is adapted to sense the pressure of the fluid within the fluid supply system. A controller is adapted to receive the sensed pressure of the fluid within the fluid supply system, to determine an expected pressure of the fluid within the fluid supply system, to identify when the sensed pressure deviates from the expected pressure, and to generate a responsive fault signal.

摘要： A two-step roller finger follower including an elongate body having side walls defining coaxially disposed shaft orifices, a pallet end and a socket end interconnecting with the side walls to define a slider arm aperture, and a latch channel. The socket end is mountable to an hydraulic lash adjuster, and the pallet end is matable with a valve stem. A slider arm for engaging a high-lift cam lobe is disposed in the slider arm aperture and has a first end pivotably mounted to the pallet end of the body and the second end forming a slider tip for engaging an activation/deactivation latch. The latch is slidably disposed in the latch channel, and the latch has a nose section for selectively engaging the slider tip. A spool-shaped roller having first and second roller elements fixedly attached to the shaft is rotatably disposed in the shaft orifices, the roller being adapted to follow the surface motion of low-lift cam lobes. Preferably, the shaft is journalled in roller or needle bearings which extend between and through the first and second shaft orifices, being thus exposed to normal copious oil flow through the RFF.
