Abstract
An improved slant axis rotary mechanism including a housing defining an operating chamber having generally radially extending opposed side walls, a shaft having an angularly offset portion journalled in the housing with the angularly offset portion within the chamber and a rotor within the chamber journalled on the angularly offset portion. The rotor includes a peripheral flange and each side of the flange has plural apices thereon, each carrying seals engaging a corresponding one of the side walls. The flange sides are slightly relieved only in the vicinity of each apex whereby sufficient clearance to prevent interference between the rotor and the housing during operation is achieved without significantly diminishing the compression ratio of the mechanism. A method of fabricating a rotor for a slant axis rotary mechanism is also disclosed.
