Abstract

A seal for facing surfaces (13, 41) of two relatively movable members comprises a sealing member (38) disposed in a groove in one member, having a sealing face (40) engaging the other member and an inclined wedge face (42) facing the base of the groove to be engaged by a complementary wedge face (43) of a thrust member (39). The fluid under pressure is supplied to the base of the groove to act on the thrust member so that the members (38, 39) fill the groove and the sealing member has its face (40) urged into engagement with the facing surface (41) of the member (16). The seal is advantageously applied to a fluid pressure operated torsional actuator, for sealing between end faces of the rotor and end parts of the actuator casing, annularly around the shaft on which the rotor is supported, and a shuttle valve arrangement supplies the seal with fluid from the actuator chamber containing fluid at the highest pressure.
