Abstract (en)

The present invention relates to a simple and straightforward positive displacement suction/pressure device (rotational clap suction/pressure device) for utilizing in general industrial flow machines, such as various positive displacement pumps, vacuum pumps, compressors, flow meters, and rotary internal combustion engines. The object of the present invention using a double non-uniform rotation is to provide a simple and durable mechanical device having improved efficiency, by replacing the existing linear contact between various types of rotors or between a rotor and a housing, which is a problem in existing positive displacement flow machines and rotary internal combustion engines, with a whole surface.
