  • Publication number: 20240003420
    Abstract: Provided is a seal device, which can reliably prevent leakage of substances from a gap in a coupling portion for two flow paths while improving ease of operation at the time of coupling the two flow paths to each other and decoupling the two flow paths from each other. The seal device includes: a first flow path (16A) which allows substances to pass therethrough; a second flow path (16B) separably coupled to the first flow path (16A); a sealing member (52), which has elasticity, and is held in a gap in a coupling portion (15) between the first flow path (16A) and the second flow path (16B); and a movable member (30) that closes the gap in the coupling portion (15) by deforming the sealing member (52) when the first flow path (16A) and the second flow path (16B) are to be coupled to each other.

  • Patent number: 11391499
    Abstract: In a heat pump cycle device, a flow passage switching portion includes a flow passage switching valve body configured to open and close a cooling side flow passage. A refrigerant circulation circuit includes a low-pressure flow passage through which a low-pressure refrigerant decompressed by a first decompressor flows toward a compressor in a heating mode, and a pre-evaporator flow passage provided between the flow passage switching valve body and a refrigerant inlet of an evaporator. The flow passage switching portion causes a pre-evaporator flow passage to communicate with the low-pressure flow passage while bypassing the evaporator when a refrigerant pressure in the low-pressure flow passage is lower than a refrigerant pressure in the pre-evaporator flow passage, in the heating mode.
