Document Type and Number:
WIPO Patent Application WO/2020/045031
Kind Code:
A1
Abstract:
[Problem] To provide a combination valve capable of achieving a reduction in the number of parts by combining a plurality of solenoid valves and an expansion valve. [Solution] A combination valve 81 includes: a housing 82 that has a first refrigerant inlet 88, a first refrigerant outlet 89, a second refrigerant inlet 92, a second refrigerant outlet 93, and a third refrigerant outlet 97; a first refrigerant passage 91; a second refrigerant passage 94; a first on-off valve part 21; a second on-off valve part 22; a third refrigerant passage 98; an expansion valve part 6 that adjusts the degree of opening of the third refrigerant passage; a drive device 83; and a check valve 18 provided in a communication path 96 that allows a section of the first refrigerant passage, the section being closer to the first refrigerant inlet than the first on-off valve part is, to communicate with a section of the second refrigerant passage, the section being closer to the second refrigerant outlet than the second on-off valve part is.
