Abstract

A sealing ring which has an annular part 36 from which extend inner and outer lips 40, 38. The sealing ring is mounted between the cylindrical surface of a bore and a piston slidable in said bore. The outer cylindrical surface (50) of the annular part 36 is normally slightly remote from the surface with which the outer lip sealingly cooperates. The annular part 36 is deformable so that the outer cylindrical surface (50) can come into sealing contact with the above mentioned surface, in order to improve fluid tightness. <IMAGE>
