Abstract
A slant axis rotary mechanism such as an engine, pump, or the like. The mechanism includes a shaft having an angularly off-set portion journalling a rotor thereon. The rotor has a peripheral flange with a plurality of apices on each side of the flange. The mechanism further includes a housing defining an operating chamber receiving the rotor and including an outer spherical peripheral wall adapted to be sealingly engaged by a seal carried by the periphery of the flange. The housing also includes spaced, generally radially extending side walls adapted to be sealingly engaged by seals carried by the rotor apices. According to the invention, the housing is defined by a pair of housing segments flanking the rotor, each segment having one of the radially extending side walls formed therein. A liner having a spherical inner surface defining the outer spherical peripheral wall is clamped between the housing segments.
