ABSTRACT:
A fluid jet ejector and ejection method wherein a plurality of high velocity jet streams of a primary fluid are discharged through a vacuum chamber into a convergent-divergent diffuser or nozzle to draw a secondary fluid into the chamber in such manner that the secondary fluid is entrained within flow spaces formed between the jet streams and is carried from the chamber through the diffuser means by the jet streams. A modular fluid jet ejector composed of multiple parts which may be economically manufactured and assembled, and a fluid jet ejector assembly consisting of multiple stacked fluid jet ejectors which may be coupled in parallel to provide a high jet pumping rate. Preferred embodiments of the fluid jet ejector include features for directing primary fluid to a flow space at nozzle exits to fill the space with primary fluid to eliminate or greatly reduce the presence of primary fluid therein, thus greatly increasing the efficiency of the ejector device, these features comprising a fluid passage about an exhaust tube for directing primary fluid flow to the flow space.
