Title:
EJECTOR
Document Type and Number:
Japanese Patent JP2014142166
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ejector integral with gas-liquid separation means capable of appropriately discharging liquid-phase refrigerant into which refrigeration oil is mixed to an outside.SOLUTION: A diffuser passage 13c for mixing injected refrigerant injected from a nozzle passage 13a with attracted refrigerant attracted from an attraction passage 13b and increasing a pressure of refrigerant mixture by arranging a passage formation member 35, and a gas-liquid separation space 30f for separating gas and liquid of the refrigerant diffused from the diffuser passage 13c by an action of a centrifugal force are formed within a body 30. An inlet 34d of an oil return passage 34c opening in the gas-liquid separation space 30f is arranged at a position closer to an outer circumference than an axial center of the passage formation member 35. It is thereby possible to efficiently flow liquid-phase refrigerant into which refrigeration oil is mixed and that is locally present on an outer circumferential side of the gas-liquid separation space 30f to the oil return passage 34c by the action of the centrifugal force.
