DEFINITION

Classification: 417/77

(under subclass 76) Apparatus in which the motive fluid and the pumped fluid are of different states (i.e., liquid and gas) and after entrainment the two are separated and the motive fluid fed back to the entrainment area as recirculated motive fluid.

(1) Note. This definition excludes a jet pump which primes the other pump of air but then acts to pump liquid when the other pump is primed.
