Abstract

A fluid seal for a rotating shaft 2 comprises a stationary annular surface 1, a resilient annular seal 4, and a ring 3 which is rotationally stationary relative to the surface 1. The seal 4 is constrained between the shaft 2 and the ring 3. The ring 3 is axially slidable and has an angled face which is urged against the seal 4 by means of a spring 5 thereby transmitting the force to annular surface 1 and the shaft 2. The seal may be urged against a stationary surface and the side face of a rotatable collar by a spring loaded member, the stationary surface and side face being at right angles to each other. The surface of the ring which engages the seal may comprise the arc of a circle or section. The ring may be biassed by a garter spring or an annular sheet metal spring. The seal may be other than circular in section.
