PROBLEM TO BE SOLVED: To provide an ejector that can avoid a structure thereof from being larger and can achieve high nozzle efficiency regardless of load variation of a refrigeration cycle.SOLUTION: An ejector includes a body 200 in which are formed: a decompressing space 202 that decompresses a refrigerant flowing out from a rotating space 140 in which the refrigerant is rotated; a suction passage 120 that suctions a refrigerant from the outside; and a pressurizing space 205 that mixes an injected refrigerant which is a refrigerant injected from the decompressing space 202, and a suctioned refrigerant which is a refrigerant suctioned from the suction passage 120, and pressurizes the mixture. The ejector also includes a conical passage forming member 151 that is disposed inside the decompressing space 202 and the pressurizing space 205. A nozzle passage 110 is defined by a refrigerant passage formed between an inner circumferential surface of the decompressing space 202 and an outer circumferential surface of the passage forming member 151. A diffuser passage 130 is defined by a refrigerant passage formed between an inner circumferential surface of a part defining the pressurizing space 205 and the outer circumferential surface of the passage forming member 151. |
