ABSTRACT:
A rotary seal interposed between an axially and rotatably movable shaft and stationary housing, the seal having a flexible annular boot or diaphragm mounted in surrounding relation to the shaft and terminating in an outer peripheral margin which abuts a seal ring, the seal ring having a tapered face engaging a sloped surface on the outer stationary housing. A spring-loaded member urges the seal ring into firm engagement with the housing portion, and the outer free end of the boot is free to be radially displaced along its interface with the seal ring while urging the seal ring in an axial direction firmly into engagement with the sloped portion on the stationary housing.
