Abstract
A rotary machine operable as a pump, compressor, motor or internal combustion engine, the machine having a rotor orbiting but not rotating within a chamber in a housing, vanes separating the space within the chamber into working chambers. The rotor is eccentrically mounted on a rotatable shaft, the rotor being guided by lobes on the rotor operating in shaped recesses in the housing. The vanes are vane assemblies biassed outwardly into contact with the chamber wall, and include a plurality of vane blades to give a labyrinth seal effect.
Claims3
A rotary machine including a housing, a chamber within the housing, a shaft concentric with the chamber and having eccentrically mounted thereon a rotor, a plurality of vanes dividing the space between the rotor and inner wall of the chamber into working chambers and valve means to control flow of fluid through said working chambers, the rotor being guided to partake of an orbital movement within the chamber by a plurality of cooperating lobes and recesses on the rotor and the housing whereby the rotor is prevented from rotation while partaking of its orbital movement characterized in that the lobes are formed on a plate attached at one end of the rotor, and the recesses are formed in a porting side plate forming a side wall of the chamber, a port in said lobe cooperating with ports in said porting side plate to form the valve means.
