EJECTOR Russian patent published in 1995 - IPC

FIELD: pumping fluids. SUBSTANCE: flow separator is made as a hollow rotation body. The side surface of the body is defined by rotation of the generatrix about the axis of the ejector. The area of the cross-section of the separator increases in the direction of the diffuser. The separator is provided with hollow members which are rigidly secured to the diffuser. The inner spaces of the members are in communication with the inner space of the separator and receiving chamber for the passive fluid. The symmetry plane of the members is coincident with the ejector axis. The front edge of the members exposed to the active fluid flow is streamlined. The area of the cross-section of the members increases in the direction of the diffuser. The faces of the members facing the side of the separator are open for flowing passive fluid. The separator is provided with supports rigidly secured to the separator and arranged symmetrically with respect to the axis in the spaces between the members. Openings are made in the side. The openings communicate the inner space of the separator with the ambient. EFFECT: enhanced efficiency. 50 cl, 9 dwg
