摘要
A rotary seal seals a high-pressure region from a low-pressure region and has an assembly sleeve made of a rubber elastic material and at least one pressure-activatable rotary seal element with a seal edge. When a specified differential pressure value is exceeded, the seal edge of the rotary seal element rests sealingly against the seal surface of a machine part, thereby directly displacing a support element elastically supported on the rubber elastic assembly sleeve. When the specified differential pressure value is undershot, the support element is moved rearwards axially in the direction of the high-pressure region such that the seal edge of the rotary seal element is moved backwards into the seal edge rest position in which the rotary seal element lies against the seal surface without contact surface pressure or substantially without contact surface pressure or is arranged at a distance from the seal surface.
