EJECTOR Russian patent published in 1995 - IPC

FIELD: pumping. SUBSTANCE: cross-sectional area of the flow separator increases in the direction of the diffuser. The outer radius of the base of the flow separator open for liquid flow and facing the diffuser is grater than the radius of the inlet cross-section of the nozzle and lesser than the inner radius of the cylindrical part of the mixing chamber. The projection of the end face, which is opposite to the base, on the plane perpendicular to the axis of the ejector is positioned inside the circumference defined by radius of inlet cross-section of the nozzle. The flow separator is provided with hollow supports rigidly secured to the separator, the inner space of the support being connected to the inner space of the separator and receiving chamber for passive fluid, and positioned symmetrically with respect to the axis. The plane of symmetry of the supports is in coincidence with the axis. The front edge, which faces toward the flow of the active fluid, is sharp at the part adjacent to the outer surface of the separator. The sides of each support is solid in the zone of the active fluid flow along the separator. Each part of the separator interposed between the adjacent supports are provided with openings which communicates inner space of the separator with outer space. EFFECT: improved design. 54 cl, 13 dwg
