Title:

EJECTOR

Document Type and Number:

WIPO Patent Application WO/2015/111112

Kind Code:

A1

Abstract:

An ejector comprising: a rotation space (221) that causes a refrigerant to rotate; a pressure-reduction space (222) that reduces the pressure of the refrigerant that has flowed out from the rotation space; a suction passage (231) that draws in refrigerant from outside; a pressure-increase space (232) that mixes injected refrigerant injected from the pressure-reduction space and the drawn refrigerant drawn in from the suction passage and increases the pressure thereof; a ring-shaped nozzle passage (224) that reduces the pressure of the refrigerant that has flowed out from the rotation space and injects same; a ring-shaped diffuser passage (232a) that mixes the injected refrigerant and the drawn refrigerant and increases the pressure thereof; a passage-forming member (240) that forms a nozzle passage and a diffuser passage; and a vibration suppression section (257) that suppresses vibration of the passage-forming member. The vibration suppression section has: a first elastic member (257a) that applies a load in a direction in which the cross-sectional area becomes smaller in a cross-section orthogonal to the central axis direction of the nozzle passage and the diffuser passage, relative to the passage-forming member; and second elastic members (257b-257g) that apply a load in the opposite direction to the first elastic member.
