Abstract
A seal between a first component (1') formed by the stationary component (2'). The first component is provided with a radially outwardly projecting annular disc (3') which grips around a ring housing (4') having a U-shaped cross section and being sealed against the second component by a compensator (7'). The inner faces of the two side walls (4'a, 4'b) of the housing are provided with concentrically arranged annular grooves (4d). A sealing ring (5) of an elastically yielding sealing material and an elastically bendable supporting ring (11) are arranged in the annular grooves so as to be axially displaceable. One side of the supporting ring lies against the sealing ring (5) while its other side is supported on springs (12) which press the sealing ring against the annular disc. The ring housing (4') is supported by hanging means (27) from a stationary supporting frame, is axially guided at the annular disc by guide rollers (23) and is secured against twisting by track rollers (24) which cooperate with bolts (9) that are fixed to the second component (2') and are parallel to the axis of rotation (1a). The seal prevents leakage if the two components (1'; 2') are subjected to great axial, radial and angular displacements and the annular disc (3') is deformed.
