ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE

WIPO Patent Application WO/2020/054071

A1

This rotary compressor comprises a compression mechanism part accommodated in an airtight container. The compression mechanism part includes at least three cylinder bodies interposed between a first bearing and a second bearing that support a rotating shaft, a plurality of partition plates provided between adjacent cylinder bodies, and a plurality of rollers that compress a working fluid within cylinder chambers of the cylinder bodies. At least three cylinder chambers are partitioned by an end plate of the first bearing, an end plate of the second bearing, and the partition plates. The end plates of the first and second bearings have first discharge ports through which the working fluid compressed in the cylinder chambers of the cylinder bodies adjacent to each of the end plates is discharged to a first muffler chamber and a second muffler chamber. Each of the plurality of partition plates that flank an intermediate cylinder body positioned between cylinder bodies adjacent to the end plates has an intermediate muffler chamber into which the working fluid flows, and a second discharge port through which the working fluid compressed in the cylinder chamber of the intermediate cylinder body is discharged to the intermediate muffler chamber.
