FIELD: machine building.
SUBSTANCE: hydraulic monitor contains two half-spheric collars, consisting of reeds, located in two layers in staggered order and forming tapered groove, accelerating working substance grooves, axial branch, on which there are located collars, and cavitator. Collars on branch are directed opposite to each other by inner surfaces, and its plates are connected so that tapered groove of one collar is proceeding of groove of other collar. Collars form one-piece symmetrical body of revolution, ehich back and front parts are stream forming and providing workability of device at direct and reverse trace in pipeline at changing of feeding direction of working agent. Invention works either at direct or at reverse trace. That provides extraction of jammed monitor from pipe, applying to it reverse trace. It is especially important at cleaning of pipelines - sag pipes, passing under river, mountain, lake etc.
EFFECT: extended capabilities.
