This integrated valve has a body, a connection member, and a drive unit. In the body, a decompression chamber for decompressing a refrigerant discharged from a compressor, and an opening and closing valve chamber for opening and closing the flow path of a refrigerant to be joined to an intermediate pressure port via an intermediate pressure refrigerant path and a check valve are formed. The connection member has a first valve body and a second valve body. The first valve body is disposed in the decompression chamber and is configured as a decompression valve for decompressing the refrigerant discharged from the compressor. The second valve body is disposed in the opening and closing valve chamber and is configured as an opening and closing valve for adjusting the flow rate of the refrigerant to be joined to the intermediate pressure port. The connection member connects the first valve body and the second valve body so that the opening and closing valve is in a fully-open state when the decompression valve is in a throttled state, the opening and closing valve is also in an open state when the decompression valve is in an open state, and the opening and closing valve is in a closed state when the decompression valve is in a fully-open state. The drive unit drives the connection member. |
