<p><P>PROBLEM TO BE SOLVED: To provide an ejector capable of sufficiently raising the pressure of an outflow fluid at a pressure raising section by sufficiently mixing an injected fluid and a sucked fluid at a mixing section. <P>SOLUTION: A rubber nozzle is applied as a nozzle 161, and a tip-tapered section 161d where a refrigerant passage area is gradually enlarged is disposed at an end at a refrigerant injection port 161a side. An expanding angleθ1 of the tip-tapered section 161d in a reference cross section including an axisϕof the nozzle 161 is an angleθ2 or smaller between first and second virtual lines L1, L2 connecting an injection port-side cross section P1 of the reference cross section and the refrigerant injection port 161a, and an outlet-side cross section P2 of the reference cross section and a refrigerant outlet 162e of the mixing section 162c. Thus the injected refrigerant and the sucked refrigerant can be properly mixed at the mixing section 162c, a flow velocity of the mixed refrigerant is increased, and thus the pressure of the outflow refrigerant can be sufficiently raised at a diffuser section 162d. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
