Abstract:
A two-stage pressurizing refrigeration cycle is provided with a suction-side guiding portion in a part of a low-stage side suction pipe that leads from a bypass branch portion, at which a bypass pipe is branched, to a refrigerant suction side of a low-stage side compressor. The suction-side guiding portion guides a lubricating oil from the refrigerant suction side of the low-stage side compressor to a side of the bypass branch portion. The suction-side guiding portion is located at a position in a vertical direction that is equal to or higher than a position in the vertical direction of the bypass branch portion, and a part of the suction-side guiding portion on the refrigerant suction side of the low-stage side compressor is located at a higher position in the vertical direction than a part of the suction-side guiding portion on the side of the bypass branch portion.

Claim (Index 5):
The two-stage pressurizing refrigeration cycle according to  claim 1 , wherein\n the high-stage side discharge pipe is provided with an oil separator to separate the lubricating oil from the refrigerant containing the mixed lubricating oil, and is connected to an oil return pipe that guides the lubricating oil separated by the oil separator to the low-stage side suction pipe, and the oil return pipe is connected to the low-stage side suction pipe at a connection portion that is positioned in the low-stage side suction pipe from the bypass branch portion to the refrigerant suction side of the low-stage side compressor.
