Abstract
An ejector includes a body part having a depressurizing space in which a refrigerant flowing out of a swirling space is depressurized, a suction passage that draws a refrigerant from an external, and a pressurizing space in which the refrigerant from the depressurizing space is mixed with the refrigerant from the suction passage, a conical passage formation member that is arranged in the body part, and a driving device that displaces a nozzle body of the body part forming the depressurizing space. A nozzle passage is defined on an outer peripheral side of the passage formation member in the depressurizing space, a diffuser passage is formed on an outer peripheral side of the passage formation member in the pressurizing space, and an actuating bar that couples the driving device with the nozzle body is arranged without crossing the diffuser passage.
