ABSTRACT:
A rotary fluid coupling which is particularly suitable for connecting a stationary source of fluid pressure to a fluid-pressure operated clutch comprises inner and outer, concentric, relatively rotatable members which have a space between them constituting a generally annular chamber for receiving pressurized fluid. The chamber is sealed to prevent the leakage of fluid by a releasable sealing mechanism which is itself fluid-pressure operated. Passages extend through the two members to connect the chamber to the stationary and rotary fluid lines. Preferably, the inner member rotates relative to the outer member which may be held relatively stationary against rotation.
