Title:
ROTARY COMPRESSOR HAVING TWO-STAGE COMPRESSION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/004730
Kind Code:
A1
Abstract:
The present invention relates to a rotary compressor having a two-stage compression structure, wherein a refrigerant suctioned into a compression space of a cylinder is compressed in two coaxially connected compression chambers and then discharged. A rotary compressor according to an embodiment of the present invention comprises a first compression part and a second compression on a single rotation shaft, and provides a structure wherein an intermediate pressure refrigerant discharged from the first compression part is introduced into the second compression part, and the maximum gas force of the first compression part can offset the maximum gas force of the second compression part, thereby reducing a reaction force applied to a journal of the rotation shaft. A rotary compressor according to the present invention provides an effect of increasing a compression cycle while securing a suction flow rate.
