PROBLEM TO BE SOLVED: To provide an ejector capable of exhibiting high nozzle efficiency and high pressure increasing performance irrespective of a fluctuation in a load of a refrigerant cycle without entailing a size increase.SOLUTION: An ejector 13 includes: a body 30 in which a decompression space for decompressing refrigerant drained from a turning space for turning the refrigerant, a vacuuming passage for vacuuming the refrigerant from an outside, and a pressure increasing space for mixing the injected refrigerant injected from the decompression space with the vacuumed refrigerant vacuumed by the vacuum passage are formed; a conical passage formation member 35 arranged within the body 30; and drive means 37 for deforming a nozzle body 32 that forms the decompression space among members constituting the body 30. A nozzle passage 13a is formed on an outer peripheral side of the passage formation member 35 in the decompression space, a diffuser passage 13c is formed on an outer peripheral side of the passage formation member 35 in the pressure increasing space, and an operation rod 38 coupling the drive means 37 to the nozzle body 32 is arranged without crossing the diffuser passage 13c. |
