| description | This pump for refrigerating systems, in particular for aeronautical applications, comprises a pump body (2) accommodating an impeller (4,16) rotatable about a main axis (3); the impeller is substantially disk-shaped and has, on at least one of its faces, a plurality of radial blades (5) arranged along a circular crown which is concentric to the main axis. The radial blades are accommodated in an annular duct (6,15,17,18) which extends in the pump body concentrically to the main axis and is axially delimited, on one side, by the blade bearing face of the impeller; the annular duct has an intake port (7) and a delivery port (8) which are angularly spaced with respect to the main axis for the inflow and outflow of a fluid and is closed in an axial direction at least in the region not affected by the ports, so that when the impeller rotates the fluid advances along the annular duct from the intake port to the delivery port forming vortices about the circumference defined by the annular duct. |
