Abstract
A seal comprised of a sealing ring (1) and a clamping ring (2) presses against the end face (3 ) of a machine part (3). The sealing ring surrounds a tubular part (12), close to the low-pressure end of which are formed a narrow sealing ridge (131) and a support part (11). The axial thrust exerted on the sealing ring (1) is transferred essentially by the support part (11) via the elastomer clamping ring (2) to the end face (31), so that the sealing ring (11) can yield in a floating manner against radial movements of the opposite operating surface. The pressure to be sealed off acts both via the clamping ring (2) on the one side and, an annular groove (422) on the other side of the tubular part (12), so that the sealing surface is essentially relieved of its load.
