ABSTRACT:
Rotary mechanisms having variable volume chambers useful for pumps, fluid motors, heat engines or the like and Stirling cycle heat engines embodying such rotary mechanisms are described. The improved volume displacement characteristics of these mechanisms result from having certain portions (apex portions) of the inner body (rotor) in continuous sealing engagement with the wall of the cavity with which it relatively rotates trochoidally, from having certain other portions (median portions) of the inner body in periodical sealing relationship with said wall during such rotation, and from having still other portions (connecting portions) always disengaged from said wall during the rotation. The Stirling cycle heat engines described have volumetric characteristics closely akin to those of an idealized engine.
