SCROLL COMPRESSOR

摘要

In a scroll compressor (A) configured such that an oil is supplied to a compression chamber (14) between fixed and movable scrolls (10), (11) and to bearings (28), (29) for a crank shaft (8), an electric motor (7) and an oil reservoir 1a are placed in a discharge chamber (22), a discharge port (11c) for discharging a gas compressed in the compression chamber (14) is formed in an end plate (11a) of the movable scroll (11), and the crank shaft (8) is provided at the inside thereof with a discharge gas passage (8e) for causing the gas discharged through the discharge port (11c) of the movable scroll (11) to flow into the discharge chamber (22). The sucked gas is prevented from being heated by a heat loss of the electric motor (7) or the oil thereby increasing the performance of the compressor (A) and a rise in cost for separating the oil from the compressed gas can be prevented.
