EJECTOR, Russian patent published in 1995 - IPC

FIELD: pumping liquids. SUBSTANCE: flow separator is made up as a hollow rotation body. The side of the separator is obtained by rotation of the generatrix about the ejector axis. The area of cross- section of the separator increases in the direction of diffuser of the conical-cylindric mixing chamber. The outer radius of the base, open for flowing liquid and facing the diffuser, is greater than the radius of the inlet cross-section of the active nozzle and lesser than the inner radius of the cylindric part of the mixing chamber. The projection of the face opposite to the separator base on the plane perpendicular to the ejector axis is arranged inside a circumference described by the radius of outlet cross-section of the nozzle. The separator is provided with supports rigidly secured to the separator and arranged symmetrically with respect to the ejector axis. The cross-section of each support is elongated over the axis. The front edge of each support is exposed to the flow and is sharp. The side of the separator is provided with openings through which the inner space of the separator is in communication with the outer space. EFFECT: improved design. 44 cl, 9 dwg
