<P>PROBLEM TO BE SOLVED: To provide an ejector type decompression device achieving sufficient mixing of a liquid phase fluid including minute air bubbles and a gas phase fluid in a mixing part. <P>SOLUTION: In an ejector device 4, a narrowing passage 412 which is a first passage of a nozzle 410 is provided with: a first inflow port 411 which is opened on the inner peripheral wall face and to which a liquid phase refrigerant from a radiator 3 is made to flow in along the inner peripheral wall face; and a second inflow port 418 which is opened on the inner peripheral wall face located at an axial end on the upstream side and to which gas having lower pressure than that of the liquid phase refrigerant and made to flow in from the first inflow port 411, is made to axially flow in. A throat part 413 which is a second passage of the nozzle 410 is provided with a turning flow suppressing means (resistor 44) for applying resistance when a turning flow formed in the narrowing passage 412 by inflow of the liquid phase refrigerant along the inner peripheral wall face is made to flow through the throat part 413 to disturb the turning flow. <P>COPYRIGHT: (C)2010,JPO&INPIT |
