As the alternative refrigerant including oil is moved from the large aperture means to the small aperture means of a tapered pipe(1c) forming several holes, the speed of flow is risen. So an alien substance, such like oil, placed on the inside of pipe is pushed by a refrigerant. The alien substance is flowed into the tapered pipe with the relatively low pressure passing several holes(1b), cause the housing(1a) surrounding the tapered pipe(1c) is connected with the low pressure side in the compressor(2) through a return pipe(1d). The flowed oil is sucked into the low pressure side in the compressor(2) through the return pipe(1d) placed on the lower side of the housing(1a) surrounding the tapered pipe(1d). This invention consists of the tapered pipe(1c) forming taper to the opposite direction of an outlet of compressor in the refrigerator, several holes(1b) formed around the tapered pipe(1c), the housing(1a) like cylinder surrounded the tapered pipe(1c), and oil return pipe(1d) extended from the lower side of the housing(1a) like a cylinder.
