Abstract
An ejector cycle device includes a compressor that draws and compresses refrigerant, a radiator that radiates heat of high-pressure refrigerant discharged from the compressor, an ejector, a branch passage branched from a refrigerant passage between the radiator and a nozzle portion of the ejector and coupled to a suction port of the ejector, a throttle unit that is arranged in the branch passage and decompresses refrigerant, and an evaporator that is arranged on a downstream side of refrigerant flow of the throttle unit in the branch passage and evaporates refrigerant. Accordingly, even when a suction performance of the ejector is lowered, refrigerant can flow through the evaporator.
