Abstract
A body of an ejector includes a diffuser passage, in which an ejection refrigerant jetted from a nozzle passage and a suction refrigerant drawn from a suction passage are mixed together and pressurized by arranging a passage formation member, and a gas-liquid separation space, in which the refrigerant flowing out of the diffuser passage is separated into gas and liquid by the action of a centrifugal force. An inlet part of an oil return passage that is open in the gas-liquid separation space is arranged at a position closer to an outer peripheral side than to an axis center of the passage formation member.
