Abstract

Axial seal (30) with retaining ring (31) and sealing ring (41) integrally fixed to this. The retaining ring (31) is composed of a thermoplastic material with extrusion-resistant core and somewhat compliant surface (32) which, owing to the compressed sealing ring (41) and the oil pressure, is pressed against the wall (22) of the gap (21) to be sealed. <IMAGE>
