摘要： A housing is configured into a tubular form and receives at least a portion of an ejector functional unit, which includes a nozzle and a body. A housing side opening radially penetrates through an outer peripheral wall surface and an inner peripheral wall surface of the housing and communicates with the fluid suction opening of the body. The housing side opening is adapted to join with a suction opening side external device, through which the fluid is drawn into the fluid suction opening.

摘要： A mixed refrigerant including a plurality of component refrigerants circulates in a refrigeration cycle device. An expansion valve includes a power element. A filled fluid filled in the power element is one component refrigerant in the plurality of component refrigerants. A slope of a saturated vapor pressure curve of the filled fluid is larger than the slope of the saturated vapor pressure curve SV0 of the mixed refrigerant. Thereby, an opening degree of the expansion valve can be prevented from exceeding in a low-temperature region, and the opening degree corresponding to a load can be obtained in a high-temperature region.
