ABSTRACT:
An improved slant axis rotary mechanism such as an engine, a compressor, a pump, or the like. The mechanism includes a housing, a shaft journalled in the housing having an angularly offset portion within the housing, and a rotor journalled within the housing on the angularly offset portion. The rotor hub has a pair of opposed grooves, each of which is adapted to receive a closed unitary annular seal which can be inserted therein to a predetermined depth. Additionally situated within each groove is a back-up spring urging the seal to bear against the housing and an O-ring providing a static seal between the seal and the groove.
