US Patent 10391839 Refrigeration cycle device

A refrigeration cycle device includes a pre-evaporator decompression unit that decompresses refrigerant which flowed out from an exterior heat exchanger, and an evaporator passage that guides the refrigerant which flowed out from the exterior heat exchanger to a suction port of a compressor while passing through a pre-evaporator decompression unit and an evaporator. Further, the refrigeration cycle device includes a bypass passage that guides the refrigerant which flowed out from the exterior heat exchanger to the suction port of the compressor while bypassing the pre-evaporator decompression unit and the evaporator, a pre-exterior device switching unit, and a passage switching unit that opens and closes the bypass passage. Further, the pre-exterior device switching unit and the passage switching unit form a coupled valve where the pre-exterior device switching unit and the passage switching unit are mechanically coupled.
