Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/211331
Kind Code:
A1
Abstract:
A rotary compressor is disclosed. The rotary compressor comprises at least one vane that is slidably inserted into a vane slot provided in a roller or a cylinder so as to separate a compression space into a plurality of compression chambers, wherein the vane has an oil supply groove formed in at least one of both axial side surfaces respectively facing a main bearing and a sub bearing, and the oil supply groove may be formed longer in the longitudinal direction of the vane than in the width direction of the vane. Through this, it is possible to suppress friction loss and wear on a friction surface by supplying oil to the friction surface in contact with the vane.
