摘要： A device for changing the relative angular position of a camshaft with respect to a crankshaft of an internal combustion engine, wherein the drive element is rotatably mounted with respect to the crankshaft and is driven by the camshaft. Between the drive element and the camshaft at least two hydraulic chambers are formed, wherein the hydraulic chambers can be pressurized with a pressurized fluid in order to set a defined relative rotational position between the drive element and the camshaft. The device includes a housing element, wherein a pressure reservoir having a pressure chamber for pressurized fluid is arranged on the housing element and wherein the basic form of the pressure reservoir is substantially cylindrical. The pressure reservoir is disposed on the housing element in such a manner that the cylindrical lateral face thereof abuts a lateral portion of the housing element, wherein at least one fluid connection is formed between the housing element and the pressure chamber of the pressure reservoir.

摘要： A camshaft phaser having a vane-type phaser having a central-position locking device having locking pins lockable in a locking slot stationary with respect to the stator and locking in the locking slot from different directions. A locking pin has a blocking portion and a flow-through pressure medium conduit, by which a fluid connection between two working chambers of different directions of action can be established or blocked in the different positions of the first locking pin. The working chambers-of the different directions of actions are capable of being short-circuited by a switching device. At least one pressure medium conduit fluidically connectable to the pressure medium circuit by the flow-through pressure medium conduit of the locking pin has a check valve therein which allows the pressure medium to flow into one of the working chambers whose volume is increased during a rotation of the rotor from either of the advance or retard stop positions toward the central locking position, while at the same time preventing backflow from the same working chamber.

摘要： A lost motion engine valve actuation system and method of actuating an engine valve are disclosed. The system may comprise a valve train element, a pivoting lever, a control piston, and a hydraulic circuit. The pivoting lever may include a first end for contacting the control piston, a second end for transmitting motion to a valve stem and a means for contacting a valve train element. The amount of lost motion provided by the system may be selected by varying the position of the control piston relative to the pivoting lever. Variation of the control piston position may be carried out by placing the control piston in hydraulic communication with a control trigger valve and one or more accumulators. Actuation of the trigger valve releases hydraulic fluid allowing for adjustment of the control piston position. Means for limiting valve seating velocity, filling the hydraulic circuit upon engine start up, and mechanically locking the control piston/lever for a fixed level of valve actuation are also disclosed.
