Abstract: An improved injector (1) which mixes a secondary fluid into a carrier fluid stream has (a) a body (2) for directing the flow of the carrier fluid, this body having an internal wall (3) forming a flow passage therethrough, a central axis, an inlet (8), an outlet (15), and a port (12) for receiving the secondary fluid that is mixed with the carrier fluid, (b) a ramp-like restriction (4) portion which is located downstream of the body's inlet (8) and upstream of the secondary fluid port (12) and configured so as to decrease the effective cross-sectional area of the flow passage in the direction of the flow of the carrier fluid, (c) a ramp-like expansion (14) portion which is located downstream of the secondary fluid port (12) and upstream of the body's outlet (15) and configured so as to increase the effective cross-sectional area of the flow passage in the direction of the flow of the carrier fluid, (d) a throat (6) portion which is situated between the restriction (4) and expansion (14) portions, and (e) a cavity (16) in the throat (6) that extends from its internal wall and into the body, with the port (12) entering the flow passage at a location in the throat cavity (16), and wherein this cavity is configured so to promote within it a vortical flow of the secondary fluid.

Abstract translation: 将二次流体混合到载体流体流中的改进的喷射器（1）具有（a）用于引导载体流体流动的主体（2），该主体具有形成通过其的流动通道的内壁（3）， 中心轴，入口（8），出口（15）和用于接收与载体流体混合的次级流体的端口（12），（b）位于下游的斜坡形限制（4）部分 的主体入口（8）和第二流体端口（12）的上游，并被构造成在载体流体的流动方向上减小流动通道的有效横截面面积;（c） （14）部分，其位于第二流体端口（12）的下游并且在本体的出口（15）的上游，并且被配置为增加流动通道的流动方向上的有效横截面面积 载体流体，（d）位于限制物（4）和膨胀物（14）之间的喉部（6）部分， 部分，和（e）喉部（6）中的空腔（16），其从其内壁延伸并进入主体，端口（12）在喉腔（16）中的位置处进入流动通道，以及 其中该空腔配置成在其内促进次级流体的涡流。
