Abstract
A compressor comprises a suction passage; an oil reservoir for storing a lubricating oil which is separated from a refrigerant gas having a discharge pressure; and a throttle valve provided in the suction passage and having a valve body for adjusting an opening degree of the suction passage based on a differential pressure applied to the valve body. The suction passage has an upstream suction passage which is located upstream of the throttle valve. The compressor comprises a lubricating oil passage connecting the oil reservoir to the upstream suction passage for the lubricating oil in the oil reservoir to flow to the upstream suction passage therethrough.
