DEFINITION
Classification: 37/322
With downstream directed jet nozzle:
(under subclass 321) Apparatus wherein a high-velocity fluid stream is forced under pressure out of an opening and is brought into contact with the dredged material to impart energy to the dredged material by the action of entrainment and frictional contact of the fluid.

137, Fluid Handling,
602+, for systems having multiple inlets and a single outlet with mixing, diffusing, or injecting means.
406, Conveyors: Fluid Current,
93+, for apparatus having means to introduce booster fluid into conveyor; subclasses 151+ for subject matter wherein the load is drawn into the conveyor by creating a vacuum at the inlet by forcing or withdrawing conveying fluid into or from the fluid flow path at a point subsequent to the inlet.
417, Pumps,
151+, for subject matter in which motive and pumped fluids are brought into intimate contact in an enclosed flow path, the motive fluid having a higher velocity than the pumped fluid and imparting energy to the pumped fluid by the action of entrainment and frictional contact.
