JET PUMP Russian patent published in 2002 - IPC

FIELD: medium transferring devices. SUBSTANCE: pump is designed for transferring one medium by means of other medium. Pump has transferring medium radial nozzle, transferred medium radial nozzles radial mixing chamber with through section decreasing in direction of movement of interacting media, and radial diffuser both radial centrifugal and radial centripetal direction of movement of interacting media. Flow passage of pump is limited by opposite side walls of first and second disk- like members installed coaxially inside pump housing with axial clearance relative to each other, and side walls of first and second injector disks installed coaxially between disk-like members with axial clearances relative to each other and relative to disk-like members. Opposite side walls of disk- like members are made with concave central part, convex peripheral part and are provided with central channels. These walls limit radial mixing chamber and radial diffuser. EFFECT: increased capacity. 5 cl, 2 dwg
