Abstract:
To suppress the situation where the production cost increases and to prevent the situation where turbulence occurs in the flow of a fluid.SOLUTION: An ejector includes: a nozzle 20 in which a drive flow is jetted from a tip opening 22; and a body part 10 which is arranged so as to surround the periphery of the nozzle 20, and in which a confluence part 13 is provided at a portion which is on the extension of the tip opening 22 of the nozzle 20. The ejector sucks a suction flow into the body part 10 through a suction inflow port 16a by jetting the drive flow from the tip opening 22 of the nozzle 20, and merges the drive flow and the suction flow at the confluence part 13. At a tip part of the nozzle 20, an outer peripheral tapered surface 23a in which an outer diameter reduces gradually toward the downstream is provided, and at the confluence part 13 of the body part 10, an inner peripheral tapered surface 13a in which an inner diameter reduces gradually toward the downstream is provided. The nozzle 20 is disposed at the body part 10 in a state where the tip part where the outer peripheral tapered surface 23a is formed is in contact with the confluence part 13.SELECTED DRAWING: Figure 1
