EJECTOR Russian patent published in 1995 - IPC

FIELD: pump engineering. SUBSTANCE: flow splitter is mounted at the outlet section of the active nozzle. The splitter is constructed as a hollow rotation body, defined by rotation of the generatrix about the axis of the ejector, and has open faces for the fluid flow. The active nozzle is ring-shaped. The splitter is conical. The lesser base of the cone points in the direction of the outlet section of the nozzle. The grater base points to the direction of the diffuser. The outer radius of the lesser base of the splitter is less than the lesser radius of the outlet section of the nozzle. The outer radius of the grater base of the splitter is grater than the grater radius of the outlet section of the nozzle. Openings are uniformly arranged over the side surface of the splitter. The openings connect the mixing chamber with the internal space of the splitter. The generatrices of the opening walls point in the direction of the diffuser and are inclined to the longitudinal axis of the ejector at an acute angle. EFFECT: improved design. 40 cl, 13 dwg
