    Abstract: A temperature sensitive rod is communicated with a diaphragm that is displaceable in response to a pressure difference between an internal pressure of a sealed space, in which a temperature sensitive medium is sealed, and a pressure of a low pressure refrigerant outputted from an evaporator. A blind hole, which opens to the sealed space, is formed in an inside of the temperature sensitive rod. The temperature sensitive medium is a mixture gas of the refrigerant and an inert gas. A mixing ratio of the inert gas in the temperature sensitive medium corresponds to a ratio of an equivalent diameter of the blind hole relative to a depth of the blind hole in such a manner that a time constant of heat conduction from the temperature sensitive rod to the temperature sensitive medium is kept within a desired time constant range.

    Abstract: An integrated valve includes a connecting member including a first valve element and a second valve element. The first valve element is disposed in a pressure reducing chamber of a body of the integrated valve and forms a pressure reducing valve that reduces the pressure of the refrigerant discharged from a compressor. The second valve element is disposed in an on-off valve chamber of the body and forms an on-off valve for adjusting a flow rate of the refrigerant flowing into an intermediate-pressure port of the compressor. The on-off valve is in a fully opened state when the pressure reducing valve is in a throttling state, the on-off valve is in an opened state when the pressure reducing valve is in an opened state, and the on-off valve is in a closed state when the pressure reducing valve is in a fully opened state.

    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.
