The invention relates to a dosage technique and can be used for applying a sealing paste.

The purpose of the invention is to simplify the design,

FIG. 1 shows the proposed device, a general view; in fig. ., 2 -; node I in FIG. 1 (shut-off valve).

The device consists of a hollow tub; 1 with a nozzle 2 for connection; with a pressure pipe, nozzle: 3 with a conical seat 4, having; at the outlet, a cylindrical calibration hole: 5, mounted in it a check valve 6 ,, working a part of which has a conical surface; 7, which passes into calibration cytg; lindr 8 and diaphragm 9., made as a part of a torus, formed by: dissecting it with a plane passing perpendicular to the axis of the torus. In this case, the outer edge of it is fixed on the cor- iiryce 1, and internally on the stop valve 6.

The device works as follows.

The paste, which is under pressure in the hydraulic chamber a, flows out of the cylindrical calibration hole 5 of the nozzle 3 in the field of the flange of the rotating cover 10 when the shut-off valve 6 is raised.

The stroke of the check valve is usually 3-5 mm. When the shut-off valve 6 moves up from its lowest position by the value of S, the elastic diaphragm travels half the distance to S

yes, a shut-off valve equal to r, therefore, an increase in the volume of the hydraulic chamber, depending on the diaphragm stroke values, is equal to

The diaphragm travel is per cross section of the diaphragm, which is limited by diameters D and d.

Thus, a stable outflow of the paste is ensured due to the fact that during the course of the shut-off valve the volume of the hydraulic chamber changes and, therefore, the pressure in it changes.

After the end of the pasteing by external command, the lever system (not shown) lowers the check valve 6 by means of the spring 11, seals the calibration hole 3 of the nozzle 3 tightly with its supporting conical surface 7, which is tightly, without gaps, mounted in the conical seat 4 of the nozzle Z. the check cylinder 8 of the shut-off valve enters the cylindrical calibration hole 5 of the nozzle 3 along the entire length of the hole 5 and completely cleans the calibration hole of the nozzle from residues
