Abstract

The invention provides a pump body assembly and a fluid machine. The pump body assembly includes a cylinder, which is rotatably arranged; a flange structure, which is located on one side of the cylinder and has a positioning boss extending into the cylinder, and a wall hollow recess is arranged on the positioning boss. The pump body assembly of the present invention solves the problem in the prior art that the flange structure obstructs the oil flow path.

Description

technical field [0001] The invention relates to the technical field related to rotary cylinder compressors, in particular to a pump body assembly and a fluid machine. Background technique [0002] Taking the rotary cylinder compressor as an example, the rotary cylinder compressor is a new type of positive displacement compressor. During the operation of the rotary cylinder compressor, the cylinder and the rotating shaft of the pump body assembly of the compressor rotate around their respective centers, and the piston reciprocates simultaneously relative to the cylinder and the rotating shaft. The rotating shaft passes through the inner hole of the piston, and the rotating shaft divides the inner hole of the piston into two cavities. The reciprocating movement of the piston relative to the rotating shaft realizes the periodic enlargement and shrinkage of the cavity, and the oil in the cavity is squeezed. The bottom continuously flows back and forth between the two cavities. ...
