HERMETIC SCROLL COMPRESSOR AND REFRIGERATION AIR CONDITIONING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve performance and reliability of a compressor while reducing cost in a hermetic scroll compressor. SOLUTION: The hermetic scroll compressor 31 is provided with a scroll compression element 40 constructed by combining each end plate 3b, 2b of a turning scroll 3 and a fixed scroll 2 to mutually side, an electric element 7 driving the same, a hermetic vessel 1 storing the scroll compression element 40 and the electric element 7 and storing lubricating oil at a bottom part, and an oil separator 10 installed on a delivery side of the scroll compressor element 40. Pressure in the hermetic vessel 1 is kept at intermediate pressure between suction pressure and delivery pressure. An oil return mechanism intermittently returning lubricating from the oil separator 10 to a slide part of the turning scroll end plate 3b and the fixed scroll end plate 2b is provided.
