ABSTRACT:
A device for the continuous variation of a relative angular position between a crankshaft and a camshaft of an internal combustion engine comprising a drive element (2) driven by the crankshaft of the internal combustion engine through a traction means, a sliding sleeve (7) which is positively locked by a first gearing (8, 9) to the drive element (2) and by a second gearing (10, 11) to a driven element (13), and an adjusting piston (6) which is fixed on the sliding sleeve (7) and guided in a housing (3) to axially delimit two pressure chambers (14, 15) which are sealed from each other by a sealing arrangement whereby a radially inward oriented sealing of the sliding sleeve (7), is achieved by providing a sealing disc (17) of continuous configuration which bears against an inner wall (19) of the sliding sleeve (7).
