Description

technical field

[0001] The invention relates to the fields of gas compression, fluid delivery and vacuum pumping, in particular to a rotary compression machine with a translational piston. Background technique

[0002] Gas compressors, fluid pumps and vacuum pumps are important general purpose compression machinery. At present, rolling piston compression machinery and rotor compression machinery, as representatives of the second generation of compression machinery, both have a crescent-shaped working chamber; the crescent-shaped working chamber is separated into an expansion chamber and a compression chamber by a slide plate; The moving piston) changes the volume of the expansion chamber and the compression chamber to realize the suction (liquid) and exhaust (liquid) of the compression machine. However, there is a problem in these two compression machines, that is, the sliding plate extends into the working chamber to isolate the expansion chamber and the compression chambe...
