Abstract
A rotary fluid seal having a flexible sealing ring which floats between relatively rotatable counterface members and has contact faces which bear on the counterfaces under the influence of centrifugal force, such as forms the subject of U.S. Pat. No. 4,348,031, is provided with a rigid spring-retaining ring which permits but limits centrifugal expansion of a spring loading the contact faces against the counterfaces.
