  • Dual face seal with radially projecting annular disc
    Patent number: 4813689
    Abstract: A seal between a first component (1') formed by the stationary component (2'). The first component is provided with a radially outwardly projecting annular disc (3') which grips around a ring housing (4') having a U-shaped cross section and being sealed against the second component by a compensator (7'). The inner faces of the two side walls (4'a, 4'b) of the housing are provided with concentrically arranged annular grooves (4d). A sealing ring (5) of an elastically yielding sealing material and an elastically bendable supporting ring (11) are arranged in the annular grooves so as to be axially displaceable. One side of the supporting ring lies against the sealing ring (5) while its other side is supported on springs (12) which press the sealing ring against the annular disc.
