摘要： The invention relates to a device (1) for hydraulically adjusting the rotational angle of a camshaft in relation to a crankshaft of an internal combustion engine. Said device consists of a drive unit (4) that forms a driving connection to the crankshaft and an output unit (5) that is connected to the camshaft in a fixed manner. The drive unit (4) has a force transmission connection to the output unit (5) by means of at least two pressure chambers (6, 7) that are configured in the device (1), which, when subjected to pressure, cause a relative torsional stress or a hydraulic loading force on the output unit (5) in relation to the drive unit (4), whilst continually compensating external hydraulic fluid leakages. The device (1) also comprises a spiral spring (8), which is located outside the device (1) and is designed to equalize the adjusting speeds in both adjusting directions. According to the invention, the spiral spring (8) is positioned in an annular chamber, encapsulated by an additional housing (11). The annular chamber can be filled completely with the external hydraulic fluid leakages of the device (1), whereby said hydraulic fluid acts simultaneously as a damping medium for the resonant oscillations of the spring windings (13) of the spiral spring (8), resulting from vibrations of the internal combustion engine.

摘要： The invention relates to a release bearing (8) used in a clutch release device (1) for actuating a friction clutch in automobiles. In order to seal an annular gap (14) that is regulated between the inner ring (9a) and the outer ring (10) of the release bearing (8), a sealing element (17a) is provided which is fixed to the inner ring (9a). In order to mount the sealing element (17a) on the inner ring (9a) in a non-positive manner, a preload spring (13) is supported on a branch (20) of the sealing element (17a).
