Abstract
The disclosure illustrates a sealing assembly for two relatively rotatable members, such as a compressor housing and a shaft for a compressor wheel. The first has an internal cylindrical surface and the second has an external cylindrical surface with an annular groove therein. The second member is disposed and rotatable within the first member and a sealing ring is disposed in the annular groove. The sealing ring is a continuous member having no circumferential gaps and made from PTFE which has sufficient elasticity to enable the radially inner diameter of the ring to be temporarily increased. It is also capable of working at the temperatures to which the assembly is subjected in use and has a low coefficient of friction.
