Title:
HERMETIC ROTARY COMPRESSOR AND REFRIGERATION AND AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/016364
Kind Code:
A1
Abstract:
This hermetic rotary compressor is equipped with a sealed container, an electric motor, two rotary compression elements driven by the electric motor, and a partition plate partitioning the two rotary compression elements. Each rotary compression element has a cylinder, a roller housed in a cylinder chamber so as to be capable of eccentric rotation, vanes dividing the cylinder chamber into a suction chamber and a compression chamber and a discharge valve device that discharges an operating fluid compressed in the cylinder chamber into the sealed container. The rotary compression element on the lower side has a cylinder stopping mechanism that stops the compression operation, and a cylinder oil flow passage that sucks up lubricating oil infiltrating the cylinder chamber. The partition plate is provided with a partition plate oil flow passage connecting the suction chamber of the rotary compression element on the lower side and the suction chamber of the rotary compression element on the upper side.
