摘要
A flow path of a nozzle included in an ejector includes a convergent taper portion in which the cross-sectional area of the flow path gradually decreases toward the downstream side, a cylindrical flow path extending from a downstream end of the convergent taper portion and being continuous for a predetermined length and in a cylindrical shape, and a divergent taper portion continuous with a downstream end of the cylindrical flow path and in which the cross-sectional area of the flow path gradually increases toward the downstream side. By providing the cylindrical flow path, a length of the divergent taper portion is reduced.
