    Placed in the pipes (1, 5, 31, 32) for withdrawing a fluid under pressure, the device automatically modifies the passage cross-sections of these pipes prompted by the drop in pressure by increasing them in proportion to this drop by the displacement of a piston (40) having cones (10, 12) which slide in the pipes (31, 32) due to the expansion of a spring (42) in the upstream direction. Because of this, the thrust resulting from the multiplication of the passage cross-sections and the expulsion pressure remains constant, thus ensuring a constant flow rate which results in a spraying with constant droplet size if the fluid is expelled through the nozzle of an atomizer (28). <IMAGE>

    The regulator includes a housing 1 with an inlet 2 and an outlet 3 channels, a differential piston 4 with a spring 5, having a smaller stage 6 with a shaped section 7 forming a throttling body 8 with the cylindrical part of the exhaust channel, and a large level 9 with a shaped section 10 forming the cylindrical surface of the housing 1 is an additional throttling body 11. The housing 1 of the flow regulator is connected to the pressure vessel. The execution on the piston 4 of the flow regulator of two conical throttling bodies provides two levels of regulation and increases the strength of maintaining the flow, 2 sludge.

    The invention relates to automation, in particular, to flow regulators used in gas-supplying vessels, which allow maintaining the consumption of a product forced from this vessel per unit of time at a constant level, during the whole period of time. emptying the internal pressure vessel.
    The aim of the invention is to improve the accuracy of the regulator.
    Fig. 1 shows a flow controller, a section; FIG. 2 shows the installation of a regulator on a gas-pressure vessel.
    The flow regulator contains a housing J with inlet 2 and outlet 3 channels, a differential piston 4 with a spring 5, having a smaller stage 6 with a profiled, .ch-k - gsok 7, forming a cylindrical tea; : s exhaust channel 3 throttled. body 8, and a large stage 9 with a profiled section-cone 10 Forming an additional throttling body 11 with the cylindrical surface of the housing 1, the piston 4 is pushed into place by the spring 5 towards the inlet channel 2 outlet channel 3. FIG. 2 shows the installation of the flow regulator housing 1 on the pressure vessel 12.
    The flow regulator operates as follows.
    In the absence of pressure in the inlet channel of the regulator, the piston-4 is in its lowest position under the action of the spring 5, while the regulator is closed.

    When the inlet channel is connected to a pressure source, for example, to a gas-pressure vessel, the working medium, compressing the spring 5, moves the piston 4 to the side of the folding carriage 3. Geometry of the profiled sections / cones) 7 and JO is chosen so that as a result of the expenditure of the working environment, the cross sections of the throttling organs Yi 1 1. under. nodding constant flow with helped fuzhin 5.
    I: - the maximum inlet pressure i 1 of the torus piston 4, compressing the spring 5, is in the extreme upper position. As the pressure decreases, N5. The consequence of the flow of the medium, the spring opens and moves the piston 4 down, increasing the throughput of the f f in proportion to the reduction to ensure a constant flow.
    The geometries of the cones 7 and 10 are calculated based on the initial pressure and the pressure drop as a percentage, depending on the pietric increase in the volume of the vessel due to the removal of the medium from it.
    The implementation on the piston of the regulator of two conical throttling bodies provides two levels of regulation and increases the accuracy of maintaining the flow.
