<P>PROBLEM TO BE SOLVED: To suppress an increase in suction pressure loss of an ejector having ribs extending upwardly outward and housed inside a cylindrical member. <P>SOLUTION: When accommodated in an ejector tank 23 formed to be cylindrical and having an inflow hole 23f formed for causing a coolant to flow on a cylindrical sidewall face, the ejector 16 having the ribs 162e extending outward is disposed so that a first area A1 formed by connecting the axial center of a nozzle 161 with an opening edge of the inflow hole 23f overlaps a second area A2 formed by connecting the axial center of the nozzle 161 with an opening edge of a coolant suction port 162c when viewed from an axial direction of the nozzle 161 of the ejector 16. Thus, a coolant passage is formed, which leads the coolant flowing through the inflow hole 23f directly to at least one coolant suction port 162c without permitting it to pass through a gap between an inner peripheral side of the ejector tank 23c and an outer peripheral side at the leading edge of each of the ribs 162e on a body side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
