A compression type refrigerator has an evaporator, a condenser, a compressor for compressing a refrigerant gas, an oil tank for storing a lubricating oil, and an oil supply device connected to the oil tank for supplying the lubricating oil to the compressor by an oil pump. The discharge side of the oil pump is connected to the oil tank through an ejector. A pipe connected at one end to the evaporator to remove a refrigerant liquid, is connected at the other end to a negative pressure generation portion of the ejector.
