Abstract

Appts. for the reception of a liquid in the form of a flow trajectory consisting in plain view of a series of widenings and constrictions, so formed and situated that the liquid on flowing through the trajectory carries out a motion oscillating round the central longitudinal flow axis. Specif., the flow trajectory exhibits a fall drop over at least part of its length in the direction of flow. Used for moving of liquids, dispersion of a solid in a liquid, aeration of a liquid, introduction of tracer elements into a liquid etc.
