Abstract

A positive displacement machine such as a pump or compressor has a drum-like housing having an interior, circular-cylindrical surface symmetrical about a main axis and having a pair of interior, planar, side surfaces normal to the main axis. A drum-like rotor is mounted within the housing for rotation relative thereto about the main axis and has an exterior, circular-cylindrical surface approximately fitting the interior, circular-cylindrical housing surface. Also, the rotor has a pair of exterior, planar, side surfaces approximately fitting the interior, planar, side surfaces of the housing. Around the rotor is a peripheral groove symmetrical about a plane normal to the main axis and disposed between the planar side surfaces of the rotor. A ring having peripheral gaps therein is mounted on the housing and projects into and substantially occupies the groove. There are axially undulatory walls on the rotor defining a channel forming approximately sinusoidal pockets disposed on opposite sides of the ring and open thereto. The pockets have circumferentially overlapping portions and are circumferentially displaced from each other. The pockets when considered together have a substantially constant axial dimension. Vanes having substantially the same axial dimension are mounted on the housing for pivotal motion through the gaps and in the pockets as impelled by the channel walls. There are ports in the housing on axially opposite sides of the ring and on circumferentially opposite sides of the vanes defining inlet and outlet passages open to the pockets.
