it is provided with a reception area 2, providing supply was through the mixing zone and separating fed stream located opposite and equal force of a pressure pipeline sections in which the fluid flows taper in opposite phases expiration and are routed through the Central apertures of the opposed spaced nozzles, with the possibility of providing on the output of the laminar fluid flows;

the pipe 2 is connected with the ends of the half rings curvilinear zones of pipelines, cut and offset from the common plane of contact with the possibility of laying a weld toroidal and opposite opposing sections of the mixing zone was and its division into two opposite directions;

circular and semicircular surface of the holes, connected to the appropriate stepped cylindrical sections of pipe 2 and, accordingly, the nozzles 5, joined by welding along a circumferential periphery of the joints, forming a rigid closed link areas of geometrically-complex pipeline liquids;

on the inner surfaces of the holes mating with the output ends of geometrically-complex piping, threaded areas, providing the possibility of equipping their conical-cylindrical nozzles with outlet section less than the internal diameter of geometrically-complex pipeline;

from pipe 2, after the separation zone was, the nozzle being constructed area of narrowing of the fluid, resulting in laminar opposed spaced threads in the cylindrical discharge outlet located opposite the nozzles.

Industrial usefulness of the new technical solutions tested on the sample 1 nozzle, which has eroded the soil and rocks mixed composition of calcium oxide (CaO), limestone, razoobrazny deposits and a variety of minerals under pressure of more than 2.5 MPa.

The novelty of technical solutions is seen at the moment for lack of better close analogues than the source /1/.

The new object is able to use clean water, along with contaminated liquid and pulp, which is valuable in terms of water reuse.

The economic feasibility of the proposed technical solution is the lack of special devices, balancing the direction of washout in manual and automated modes that creates increase the rate of penetration grooves in the first stage of separation of the species of the soil, when doing cutting breed, both outside and under water.
