Abstract
An ejector cycle device includes a compressor, a refrigerant radiator disposed to radiate heat of refrigerant discharged from the compressor, an ejector having a nozzle, a first evaporator for evaporating refrigerant from the ejector, a branch passage, which is branched from a refrigerant downstream side of the refrigerant radiator and is connected to a refrigerant suction port of the ejector, a throttle member disposed in the branch passage to decompress refrigerant flowing from the refrigerant radiator, a second evaporator disposed in the branch passage between the throttle member and the refrigerant suction port of the ejector, and a gas-liquid separator having an inlet connected to a downstream side of the first evaporator and an outlet from which gas refrigerant is introduced to a refrigerant suction side of the compressor. Thus, refrigerant amounts flowing to the first and second evaporators can be suitably controlled.
