ABSTRACT:
An improved rotary mechanism such as a rotary engine provided with improved seals. The mechanism includes an operating chamber with a rotor therein, the rotor being provided with at least one seal receiving groove. An improved seal is located in the groove and comprises a seal element extending partially out of the groove, a spring secured to the seal for biasing the seal into sealing engagement with the chamber walls, and a carrier element secured to the spring. The carrier element includes resilient means having an unstressed width slightly greater than the width of the groove to grip the groove to positively retain the unitized seal assembly therein.
