Abstract

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.

Description

TECHNICAL FIELD[0001]The present invention relates to a positive displacement suction / pressure device that is utilized in overall industrial fluid machines such as various positive displacement peristaltic pumps, vacuum pumps, gas compressors, positive displacement air blowers, gas and liquid flow meters, or rotary internal combustion engines, and more particularly, to a positive displacement suction / pressure device (hereinafter, referred to as a “rotational clap suction / pressure device”) in which two rotational piston blades are rotated in the same direction as if a person clap his hands so that a change in volume between the blades is used for suctioning a fluid.BACKGROUND ART[0002]Recently, a vane pump and a gear pump which have relatively simple structures and a piston and plunger type pump and a screw pump which are relatively complicated and have relatively large scales are widely used as positive displacement liquid transfer pumps.[0003]In general vacuum pumps, a vane pump, a...
