ABSTRACT:
A rotary valve has a fluid seal ring which is loosely captured within a valve body and provides a fluid seal at a peripheral edge of a movable member selectively positionable in a fluid conduit. The seal ring has an annular coaxial recess located on an inner side face thereof. A fixed valve seat member retained in the valve body coaxially with the seal ring has an outwardly projecting cantilever beam in the form of an integral annular ring located on a side face thereof. The end of the cantilever beam is provided with a tapered face arranged to cooperate with a tapered wall surface defining a side of the recess within the seal ring. The contact between the tapered side face of the cantilever beam and the tapered recess surface provides a fluid seal which is selectively positionable along the tapered recess surface to permit a self-aligning action of the seal ring to accommodate varying mechanical eccentricities of the seal ring in its fluid sealing position.
