ABSTRACT:
An ejector decompression device for a refrigerant cycle includes a nozzle which decompresses refrigerant flowing out of a refrigerant radiator, and a pressure increasing portion which increases a pressure of refrigerant while refrigerant jetted from the nozzle and refrigerant drawn from an evaporator are mixed. In the ejector cycle, a coaxial degree of the nozzle with respect to the pressure increasing portion is in a range between 0-30% of an inlet diameter of the pressure increasing portion. Alternatively, the pressure increasing portion has a taper portion at least in a predetermined range from the inlet of the pressure increasing portion, and the taper portion is provided to increase a passage sectional area from the inlet of the pressure increasing portion. Accordingly, collision of high-speed refrigerant jetted from the nozzle to an inner wall surface of the pressure increasing portion can be restricted.
