ABSTRACT:
A fluid power converter having a rotor and stator rotatable with respect to one another about a common axis and having coacting sides in which an annular seal is positioned between the coacting sides for limiting fluid flow therethrough thereby providing increased efficiency and maintaining rotor vane fluid loading. Preferably, the center of the annular seal is eccentrically positioned relative to the common axis whereby the seal continuously and periodically changes its radial sealing contact with the side of at least one of the members for providing a long life side seal. An annular retaining ring connected to one of the members and positioned inside of said seal and including a second seal between the inner ring and the annular seal. Resilient means acting between said one member and the annular seal for resiliently urging the annular seal towards the second member.
