摘要： A hydraulic device in an internal combustion engine for adjusting a rotation angle of a camshaft in relation to a crankshaft includes a tubular stator and a rotor connected in fixed rotative engagement with the camshaft and having plural vanes in spaced apart relationship to define pressure chambers on both sides of the vanes. The stator is connected in fixed rotative engagement with a crankshaft-drive timing pulley and constructed to define with the rotor vanes the pressure chambers. The stator is made by a shaping process without material to effect a mass reduction. Pressure medium is supplied to or purged from the pressure chambers to selectively adjust the position of the rotor in relation to the stator and thereby the position of the camshaft in relation to the crankshaft.

摘要： A hydraulic device in an internal combustion engine for adjusting a rotation angle of a camshaft in relation to a crankshaft includes a tubular stator and a rotor connected in fixed rotative engagement with the camshaft and having plural vanes in spaced apart relationship to define pressure chambers on both sides of the vanes. The stator is connected in fixed rotative engagement with a crankshaft-drive timing pulley and formed in single-piece construction with an end wall to thereby exhibit a pot-shaped structure. The pot is made without material removal from a sheet metal part and constructed to define with the rotor vanes the pressure chambers. Pressure medium is supplied to or purged from the pressure chambers to selectively adjust the position of the rotor in relation to the stator and thereby the position of the camshaft in relation to the crankshaft.

摘要： An apparatus for variably adjusting control times of gas exchange valves in an internal combustion engine. The apparatus has a driving element, an output element, at least one pressure chamber, a pressurized medium supply device, and at least one pressure accumulator. The supply device allows pressurized medium to be fed to or discharged from the pressure chamber. A phase angle of the output element relative to the input element can be changed by feeding or discharging pressurized medium to or from the pressure chamber. The pressure accumulator encompasses a movable element that has a first pressure surface which partially delimits a storage space. The storage space is or can be connected to the supply device. An energy store applies a force to the movable element in the direction of an initial position. The movable element can be moved against the force of the energy store by pressurizing the storage space.

摘要： The invention relates to a device (101) for varying the control times of gas exchange valves of an internal combustion engine, with a hydraulic actuation device (102) and with a control valve (103). The device (101) according to the invention is provided with mid-position locking of a hydraulic actuation device (102). Furthermore, the device (101) according to the invention ensures that, in the event of the failure of an actuation unit (112) which regulates the control valve (103), the hydraulic actuation device (102) is locked in the mid-position and the lock is maintained until the actuation unit (112) is repaired. Furthermore, the device (101) according to the invention makes it possible to start the internal combustion engine in a position locked in a mid-position, without a movable element (105) of the hydraulic actuation device (102) butting against a side wall of a pressure space (104) when the internal combustion engine is started. Methods are proposed to bring the actuation device (102) into a locked mid-position, and to hold it there, for the restarting of the internal combustion engine.
