摘要： A fluid injector assembly for drawing a first fluid into the flow of a second fluid. The injector assembly includes an eductor including an inlet having a plurality of openings, a first outlet port, and a first fluid passage extending between the inlet and the first outlet port. The openings are generally disposed tangentially to the first fluid passage. The inlet is adapted to be placed in fluid communication with the second fluid such that the second fluid flows through the first fluid passage from the inlet to the first outlet port. The fluid injector assembly also includes a throat having an inlet port, a second outlet port and a second fluid passage extending between the inlet port and the second outlet port. The inlet port of the throat is spaced apart from the first outlet port of the eductor forming a gap therebetween. The gap is adapted to be placed in fluid communication with the first fluid. As the second fluid flows through the first passage, the tangential openings of the eductor cause the second fluid to swirl as the second fluid flows through the first fluid passage and to form a vortex in the gap as the second fluid flows out of the first outlet port. The vortex of the second fluid creates a low pressure zone within the gap which draws the first fluid into the gap wherein the first fluid and the second fluid enter the inlet port of the throat and flow through the second fluid passage.
