Operation of the ejector cycle is schematically described with reference to FIG.3. The refrigerant discharged from the compressor10is circulated to the radiator20. The refrigerant, which is cooled by the radiator20, is isentropically depressurized and is expanded by the nozzle arrangement41of the ...
Next, an operation of the present embodiment with the above-described structure will be described. When the compressor2is rotated by the drive force of the vehicle engine, the high temperature and high pressure refrigerant, which is outputted from the compressor2, enters the radiator3where the ...
The load is not limited to the motor3for the fuel pump. The load may be a direct-current motor, such as an electric fan for a radiator or a motor for a blower. The load may be a solenoid actuator or a solenoid valve, and may be a resistance such as a heater for an airconditione...
the refrigerant is not condensed and liquefied even if being cooled. In this case, the condenser12functions as a heat radiator that cools the high-pressure refrigerant. A refrigerant outflow side of the condenser12is connected to an inflow part141(to be described in detail later) of the eject...

A reference character 880 shows an upstream cooling-air passage formed among the condenser 850, the radiator 840, and the radiator fan 820 and extending in the longitudinal direction. The downstream outlet 872 of the suction duct 870 is for example directed toward the one side (left side or ...
by a pump66provided in the cooling liquid circulation path63. The cooling water, the radiator64, the radiator fan65and the pump66in this embodiment are shared with an engine cooling circuit mounted in a vehicle; however, alternatively they may be provided separately from the engine cooling ...
of the vehicle AC generator100, the parts of the cooling fin unit252that protrude outside the rear cover27will be cooled by a flow of cooling air from the radiator fan of the vehicle engine. Hence, the cooling performance during such low rotation speed operation can be substantially enhanced...
