HORIZONTAL SCROLL COMPRESSOR

PROBLEM TO BE SOLVED: To prevent refrigerating machine oil from flowing out of a compressor, to supply oil in an oil retention chamber to a sliding part of a bearing, and to reduce the amount of oil rise in a horizontal scroll compressor.SOLUTION: In the horizontal scroll compressor, compressed gas is discharged from a discharge pipe provided to a hermetic vessel holding a compressor mechanism and an electric motor part. The inside of the hermetic vessel is separated by a supporting plate into a first space holding the compressor mechanism and the electric motor part, and a second space provided with the discharge pipe. A communication path is provided below the supporting board so as to allow the bottom of the first space to communicate with the space above a driving shaft in the second space. When a difference in oil levels is increased during high speed operation, the oil levels are adjusted through the communication path. In order to stabilize the oil supply to oil the bearing, the oil is supplied by an oil pump placed at the end of the driving shaft near the oil retention chamber.
