Title:
Ejector
Document Type and Number:
Japanese Patent JP6003844
Kind Code:
B2
Abstract:
An approximately conical passage-forming member is disposed inside a body in which a swirling space for swirling a refrigerant is formed, and an ejector defines therein a nozzle passage that functions as a nozzle for depressurizing a refrigerant that has flowed out from the swirling space between an inner circumferential surface of the body and the passage-forming member, and a diffuser passage that pressurizes a mixed refrigerant obtained from a refrigerant sprayed from the nozzle passage and a refrigerant drawn from a suction-passage. A plurality of driving passages through which a refrigerant is introduced from a distribution space to the swirling space are formed in the body. In this case, the driving passages are formed in a manner such that a refrigerant flowing in from each driving passage into the swirling space flows along an outer circumference of the swirling space and flows in directions different from each other. Accordingly, nozzle efficiency is sufficiently improved.
