    Abstract: In an integration valve, a body, in which a vapor-liquid separating space is provided, includes a fixed throttle decompressing liquid-phase refrigerant, a liquid-phase refrigerant side valve body member opening or closing a liquid-phase refrigerant passage, and a vapor-phase refrigerant side valve body member opening or closing a vapor-phase refrigerant passage. Further, the vapor-phase refrigerant side valve body member is configured by a differential pressure regulating valve operated based on a pressure difference between a refrigerant pressure at a side of the vapor-phase refrigerant passage and a refrigerant pressure at a side of the liquid-phase refrigerant passage. The vapor-phase refrigerant side valve body member is movable when the liquid-phase refrigerant side valve body member is moved by a solenoid. Therefore, a cycle configuration of a heat pump cycle configuring a gas injection cycle can be simplified.

    Abstract translation: 在集成阀中，设置有气液分离空间的主体包括固定节气门减压液相制冷剂，打开或关闭液相制冷剂通道的液相制冷剂侧阀体构件，以及 气相制冷剂侧阀体构件打开或关闭气相制冷剂通道。 此外，气相制冷剂侧阀体构件由基于气相制冷剂通路一侧的制冷剂压力与液相制冷剂侧阀侧的制冷剂压力之间的压差而动作的差压调节阀构成， 相制冷剂通道。 当液相制冷剂侧阀体构件通过螺线管移动时，气相制冷剂侧阀体构件可移动。 因此，能够简化构成气体注入循环的热泵循环的循环结构。

    Abstract: A first valve member switches between a first communication state, in which a first inlet passage communicates with a first outlet passage and a second inlet passage is closed, and a second communication state, in which the second inlet passage communicates with the first outlet passage and the first inlet passage is closed. A second valve member switches between an opening state and a throttle state in which a smaller volume of a fluid flows from the third inlet passage to the second outlet passage as compared to the opening state. A valve driving member switches between a first operation state, in which the first valve member sets the first communication state and the second valve member sets the opening state, and a second operation state, in which the first valve member sets the second communication state and the second valve member sets the throttle state.

    Abstract: 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.
