ABSTRACT:
A rotary face seal located about a shaft and urged into seal face contact with a stationary seat formed on a housing which contains pressurized fluid. In order to overcome distortion of the seal due to the fluid pressure, which is likely to cause wear of the seal face, the seal is subjected to a radial compressive pre-stress applied between an elastomeric, e.g. rubber, strip and a support ring.
