DEFINITION

Classification: 417/186

(under subclass 182) Apparatus in which the motive fluid is directed into the entrainment area by a nozzle and valve means are provided which when actuated cause all or a portion of the motive fluid to be diverted from the nozzle.

(1) Note. The diversion of the motive fluid may be merely around the nozzle to reenter the pump downstream of the normal entrainment area or the diversion may be away from the pump as, for example, into the normal pumped fluid inlet line.

SEE OR SEARCH THIS CLASS, SUBCLASS:

185, for main line control downstream of the entrainment area which may cause an increase in motive fluid pressure so as to by-pass.
