Abstract
A horizontal type scroll compressor is provided with a support plate separating an inside of the sealed container into a first space in which the compressor mechanism portion and the electric motor portion are stored, and a second space in which the discharge pipe is provided, and a communication path communicating a bottom portion of the first space and a space above the drive shaft within the second space in a lower side of the support plate, and regulates an oil level by the communication path in the case that the oil level difference becomes large at a time of a high-speed operation. In order to stabilize the oil supply to the bearing or the like, the oil is supplied by an oil pump provided in a shaft end portion of the drive shaft close to an oil reserving chamber.
