In a seal (1) of shafts (7) relative to a medium, being received in housing-fixed support rings (4, 5), it is provided that in an embodiment of the seal with a clamp-in element (3) and an angled element with a seal lip (2) arranged via an intermediate part (6) whereby a contact pressure is applied via a spring (10). For this it is provided that the spring (10) is embodied in a receiving groove (11) as a spring pocket with a free space (12) for the spring in the pressureless state. A nose (13) as a retaining element for the inserted spring is arranged on the membrane as an intermediate part (6) above the spring pocket (11). The membrane is adjustable upon changing a tilt angle (Psi) by pressure loading up to reaching a limit pressure for contacting on an allocated housing wall (16) such as an extended support ring (5). Thereby an enlarged bottom side contact angle (beta) is established in the angled region with the seal lip (2). |
