PURPOSE:To simplify the assembly and brazing for a refrigeration cycle by connecting a check valve and a discharge-gas cut-off valve onto the inlet side and the outlet side of an evaporator by piping the gas intake port and the gas injection port of a compressor mechanism into a refrigeration cycle. CONSTITUTION:A check valve 8 installed into a gas intake port 4b of a coolant compressor 4 and a discharge-gas cut-off valve 18 connected to a gas injection port 11 are provided integrally. Therefore, the check valve 8 and the discharge- gas cut-off valve can be connected to the inlet side and the outlet side of an evaporator (not shown in the figure) by piping the gas intake port 4b of the compressor and the gas injection port 11 into a refrigeration circuit. With such constitution, the assembly and brazing for the refrigeration cycle are simplified, and a number of manhour can be economized. Further, since a solenoid valve can be omitted, the electric-power cost for the valve can be saved, and energy economization is permitted, and since the necessary material can be reduced, cost cut is permitted markedly.
