ABSTRACT:
A hermetic type scroll compressor according to the invention includes a scroll compressor element in which an end plate of a orbiting scroll and an end plate of a fixed scroll are assembled such that they slide against each other, an electric motor element which drives the scroll compressor element, a hermetic casing housing the scroll compressor element and the electric motor element and holding lubricating oil collected at a bottom thereof, and an oil separator disposed on a discharge side of the scroll compressor element. An interior of the hermetic casing is kept at an intermediate pressure between a suction pressure and a discharge pressure. An oil return mechanism is provided, which intermittently returns lubricating oil from the oil separator to sliding parts of the orbiting scroll end plate and the fixed scroll end plate. The hermetic type scroll compressor31can be improved in performance and reliability while promoting cost reduction.
