Claims

[Claims for Utility Model Registration] A rotor having five vanes at equal intervals is inserted into a cylinder to divide the cylinder chamber into two compression chambers, and five working chambers are formed by the five vanes. The rear side and front side of the rotor shaft are supported by bearings, and the bearings communicate with annular oil grooves provided on both sides of the rotor shaft. A rotary compressor consists of a lubricating oil path that runs through a groove, a vane insertion hole, a front annular oil groove, a front bearing, and a mechanical seal chamber to the front side wall of the rotor. A rotary compressor according to claim 1, in which the bearing supporting the two rotor shafts is a ball bearing. 3. The rotary compressor according to claim 1, wherein the bearing that supports the three rotor shafts is a twenty-one dollar bearing. −
