摘要：
In an ejector, a refrigerant passage of a nozzle for decompressing and expanding refrigerant includes a throat portion in which a refrigerant passage sectional area is most reduced, a first taper portion arranged downstream of the throat portion to gradually enlarge the refrigerant passage sectional area, a second taper portion arranged downstream of the first taper portion to gradually enlarge the refrigerant passage sectional area, and an end taper portion arranged in a range from an outlet side of the second taper portion to a refrigerant jet port to gradually enlarge the refrigerant passage sectional area. Furthermore, a second expanding angle at the outlet side of the second taper portion is larger than the first expanding angle at the outlet side of the first taper portion, and an end expanding angle at the outlet side of the end taper portion is smaller than the second expanding angle.
