Abstract

The rotary end face seal has primary and pressure rings rotating in relation to each other and with radial sealing faces bearing against each other. The outer periphery of the pressure ring is sealed to its support. Contact between the pressure ring (17) and its support (33) in the axial direction is limited to a radially outer portion of the ring. The centre of gravity (31) of a quarter axial section of the ring is situated radially inwards from the contact zone. One of these faces is of reduced thickness at various points on the periphery so as to form hydraulic cushions.
