Abstract:
A rotary mechanism including a housing defining a chamber including an operating cavity, a shaft journalled by the housing, and a rotor within the chamber and journalled on the shaft, the rotor having a plurality of apices on one side thereof. There is a plurality of apex seal-receiving grooves in the rotor, one at each apex, and at least one peripheral seal-receiving groove in a different surface of the rotor and intersecting the apex seal-receiving grooves. The mechanism includes a plurality of elongated apex seals, one at each apex seal-receiving groove, and each apex seal has a first groove in an end thereof in substantial alignment with the peripheral seal-receiving groove and a second groove opening into the corresponding apex seal-receiving groove. Peripheral seals are disposed in the peripheral seal-receiving groove and extended therealong substantially to the first grooves in the apex seal ends. A plurality of first seals is provided, one in each of the first grooves, along with a plurality of second seals, one in each of the second grooves. Thus, the first and second seals substantially seal the intersections of the apex and peripheral seals.
