PROBLEM TO BE SOLVED: To provide an ejector which can perform an operation adapted to a load of a refrigeration cycle while suppressing the enlargement of a physique.SOLUTION: A high-pressure refrigerant which flows in from a refrigerant flow-in port 211 is swirled in a body 200, and a swirl space 221 for introducing the swirling high-pressure refrigerant into a decompressing space 222 which decompresses and expands the high-pressure refrigerant is formed. Then, a shape of a passage forming member 240 which forms a nozzle passage 224 and a diffuser passage 232a is formed into such a shape that a cross section area is expanded as separating from the decompression space 222. Furthermore. a temperature sensing part 252 of drive means 250 which displaces the passage forming member 240 is accommodated in the body 200, and shapes of the temperature sensing part 252 and a diaphragm 251 are formed annular so as to surround at least an axial line X of the passage forming member 240. |
