ABSTRACT:
To provide a seal between a rotatable tubular member and a stationary housing, which surrounds the end of the tubular member, a gripping device is non-rotatably secured to the outside peripheral surface of the rotatable tubular member and a sealing element is provided, which is radially movably disposed in the gripping device and rotates with the latter and is in sealing relation to the housing. In order to ensure an effective seal regardless of axial and radial movements of the rotatable tubular member, and to provide a simple structure, which is non-susceptible, the gripping device consists of two spaced apart rings, which are secured to the outside peripheral surface of the rotatable tubular member. Each ring is provided on its inside near its outside diameter with a resilient sealing and restraining element, which protrudes from the surface of the ring. A sealing washer is gripped between the restraining elements and is radially and tangentially displaceable relative to the restraining elements. The circular outer rim of the sealing washer is in sealing relation to and self-centering in the housing and defines only a small clearance therewith.
