Abstract

The invention relates to a sealing ring which is particularly suitable for sealing off a piston in a cylinder bore and with which there is no risk of scuffing on the cylinder wall. The sealing ring consists of an elastically deformable band which is provided with an oblique slot in such a way as to give two parallel bevelled ends. When the band-shaped sealing ring is inserted into the cylinder bore, the oblique ends slide freely against one another so that the ring is compressed in the bore and comes to rest in a sealing manner against the piston. Pressure in the cylinder bore produces a wedging effect between the oblique ends, leading to the expansion of the sealing ring against the cylinder wall to produce a seal.
