(under subclass 151) Apparatus in which in a single zone of entrainment of pumped fluid (i.e., single inflow of pumped fluid and single outflow of combined pumped and motive fluid) there is provided means to project a plurality of separate motive fluid streams or different sources of motive fluid are provided for delivery through the same motive fluid projecting means.
(1) Note. The separate motive fluid streams or sources may be used simultaneously or alternately.
SEE OR SEARCH THIS CLASS, SUBCLASS:
163, for successive introduction of motive fluid into the pumped fluid along the path of flow of the pumped fluid.
174, for successive entrainment of pumped fluid by a single motive fluid flow.
176, for plural motive fluid jets having separate combining tubes from the jets.
