Rotary feedthrough seal for rotary feedthrough of rotary feedthrough arrangement of hydraulically operatable clutch device, has two sealing rings, where one of sealing rings has larger elasticity than other sealing ring

摘要

The seal (28) has a sealing ring (42) for supporting the seal at another sealing ring (30) in radial directions (14, 16), where the former sealing ring has larger elasticity than the latter sealing ring. Free ends of the latter sealing ring are connected with each other in axial directions (10, 12) and/or radial directions. The free ends are formed such that fluid flowing in the axial directions is deflected in circumferential directions (18, 20) and/or radial directions based on cross-sectional height of the latter sealing ring. Independent claims are also included for the following: (1) a rotary feedthrough arrangement with an inner component and an outer component (2) a hydraulically operatable clutch device comprising a hydraulically propelable actuating piston.
