Abstract:
An ejector includes a nozzle, a suction chamber, and a diffuser. An outlet flow path includes a narrowed flow path having a first tapered surface narrowed toward downstream, a parallel flow path having a constant sectional area, and a parallel flow path having a second tapered surface expanded toward downstream. The diffuser further includes an attachment configured to change the dimensions of the outlet flow path. The attachment changes the dimensions of the outlet flow path such that the ratio of the tapered angle of the first tapered surface to the tapered angle of the second tapered surface is higher as the sectional area, i.e., the inner diameter, of the parallel flow path is smaller.

Claim (Index 7):
A method for setting an outlet flow path of a diffuser including an outlet flow path having a narrowed flow path having a first tapered surface narrowed toward downstream, a parallel flow path connected to a downstream end of the narrowed flow path and having a constant sectional area, and an expanded flow path connected to a downstream end of the parallel flow path and having a second tapered surface expanded toward downstream and used for an ejector, comprising:\n a step of setting a sectional area of the parallel flow path; and a step of setting a dimension of the outlet flow path such that a ratio of a tapered angle of the first tapered surface to a tapered angle of the second tapered surface is higher as the sectional area of the parallel flow path is smaller.
