BALL-SHAPE COMPRESSOR AND EXPANSION COMPRESSOR CAPABLE OF REALIZING MULTISTAGE COMPRESSION

摘要

A kind of compressor capable of implementing multistage compression is characterized by that several working chambers are set in a ball cylinder,the ball internal cavity has three movable elements: a piston (3), a dial (5) and a spindle (8). The air channel is set on the piston and piston hinge support (10), intake and exhaust channel is set on the cylinder body (1) and cylinder cover (2). When the piston is rotated into each working chamber and has need of in-taking air and exhausting air, the correspondent air channel is communicated with intake and exhaust channel so as to implement multi-stage compression and expansion.
