Abstract
An ejector includes a body member having a depressurizing space that depressurizes a refrigerant which flows out of a swirling space that swirls the refrigerant, a suction passage that draws the refrigerant from an external, and a pressurizing space that mixes a refrigerant jetted from the depressurizing space with a refrigerant drawn from the suction passage and pressurizes the mixed refrigerant, and a conical passage formation member arranged in the depressurizing space and in the pressurizing space. A nozzle passage is formed of a refrigerant passage between an inner peripheral surface of the depressurizing space and an outer peripheral surface of the passage formation member, and a diffuser passage is formed of a refrigerant passage between an inner peripheral surface of a portion that defines the pressurizing space and an outer peripheral surface of the passage formation member.
