ABSTRACT:
A scroll compressor has a closed container 1 with a bottom serving as an oil storage 10 reserving lubricating oil 9. A gas-liquid separator 28 is provided near the closed container 1. An intake pipe 23 is connected to an upper end of the gas-liquid separator 28. An intake gas connecting pipe 29 extends normal to the axial direction of the gas-liquid separator 28 to connect the upper part of the gas-liquid separator 28 with the closed container 1. Meanwhile, a connecting pipe 24 is provided to connect the bottom of the gas-liquid separator 28 with the oil storage 10 in the closed container 1. Furthermore, there in provided a filter 30 between the intake pipe 23 and the intake gas connecting pipe 29. Thus, oil amount introduced into the compressor is reduced. Reliability is increased, and efficiency of air-conditioning apparatus is improved.
