    The invention relates to aerosol packaging and can be used to regulate the head. The aim of the invention is to provide a constant consumption of the substance sprayed by aerosol packaging. By pressing the pusher 9, the substance from the aerosol package is released under the action of pressure. The piston 5 moves forward not only under the action of a substance, but also due to the effective suction created at the inlet of the channel 23 as a result of the expansion of the substance under pressure and due to its vortexing. Spring 20 compression is calibrated depending on the pressure of the substance. At the beginning of the adjustment, it is very weak in order to overcome these two forces, and therefore the piston 5 remains in place. As soon as a part of the substance comes out of the package, the outward pressure decreases, the compression spring 20 pushes the piston 5 into an adjustable position corresponding to the residual pressure value. Therefore, to obtain from the very beginning a continuous movement of the piston 5, it is necessary to use a differential spring 20 of compression. 14 з.п, ф-лы. O) 5 4 4ib ss with 4i CH

    Section 6 of the differential piston 5 may be at least 90% of the cross section of section 2 of a larger diameter of the output channel.
    The length of section 6 of a larger diameter of the differential piston 5 may be at least equal to or 25% longer than the length of section 2 of a larger diameter of the output channel.
    The volume of the differential piston 5, located in the chamber
    13 may not exceed 16% of its volume.
    The cross section of the annular groove 15 can be 50% of the total sections of the channels
    14. In case 1, a compression spring 20 can be installed, the length of which is at least equal to the length of the section
    3 of the average diameter of the output channel j in this case, it can be mounted in such a way that it abuts against the section 6 of the differential piston 5 having a larger diameter. The outlet channel may have a bend, and in the front part of the differential piston, which is located first in the direction of fluid flow, a chamber 21 is formed, the compression spring 20 can be made with a variable section, and in the section 6 of the differential piston 5, which has the largest diameter, there are slots 22, parallel to its axis.
    A channel 23 is also formed in the housing 1. In another embodiment, there are a valve 24 comprising a housing 25 and a seat 26, a spring 27, an output channel 28, a jet 29 located at the outlet, a core 30 mounted between them with protrusions 31, a cylinder 32. In another In the variant of the regulator (Fig. 3), the core 30 can be made integral with the jet 29, with all the elements being inserted into the assembly cylinder 33. Channels 34-37 can be made in housing 1. These channels together form an output channel, the differential piston 5 consists of three parts, each of which is a throttling adjustment of small diameter 38, average diameter 39 and larger diameter 40. In addition, the piston 5 has a bearing surface 41 for compression 20. and cuts 42 and 43 „
    The force of the spring 20 is compressed so that it is complete
    The pressure is compressed when the pressure of the substance is 5 bar, allowing the piston 5 to press against the core 30, which in this case serves as a limiter of the piston code 5, the core 30 is inserted into the orifice 29 so that it forms a gap with the 44 of the orifice 29.
    The regulator works as follows.
    When the push rod 9 is pressed, the substance from the aerosol package is released under the action of the highest pressure, while the differential piston 5 moves forward not only under the action of the substance, but also due to the suction effect created at the inlet of the channel 23 as a result of expansion of the substance under pressure due to the turbulence of the substance. Compression spring 20 is calibrated depending on the pressure of the substance without taking into account the suction force. At the beginning of the adjustment, it is very weak in order to overcome these two additional forces and the differential piston 5 remains in place. As soon as a part of the substance leaves the package, the discharge pressure decreases, the compression spring 20 pushes the differential piston 5 into an adjustment position corresponding to the residual pressure value. Thus, to obtain from the very beginning a continuous movement of the differential piston 5, it is necessary to use a differential compression spring 20, which initially develops a greater force than the rest of the expansion section
    In another embodiment of the pressure regulator, the pusher 9 through the rod 10 and the gasket 18 presses the valve 24, which includes the housing 25 and the seat 26, and, compressing the spring 27, opens it. On one side, the substance enters the chamber 21 of the differential piston 5, and on the other side flows along the differential piston 5 into the output channel 28. Under the pressure of the substance, the differential piston 5 moves in the direction of the orifice 29 and compresses the compression spring 20. The end face of the differential piston 5 rests firmly on the center of the core 30, the piston 5 is located inside the chamber 13, reducing its volume. Since the protrusions

    The 31 cores 30 and the end face of the nozzle 29 are in close contact with the cylinder 32, BenjecTBO under pressure can approach the nozzle 29 only through the channels 14. Since these channels are perpendicular to the channel 28, a vortex is formed at the exit of the channels 14. Due to the fact that the channels 14 are tangential to the chamber 13, the flow of matter, although turbulent, has a rotational direction of movement, and the annular groove 15 turns this turbulent flow into a laminar flow that goes to the nozzle 29 through the channels 16. Inhibition of the flow of matter is part of the flow control per unit of time, since the compression spring 29 can be decompressed and open the cross section for the passage of the substance at the level of all the parts of the piston 5.
    In order for the substance to be released under the full available pressure, the rod 10 of the pusher 9 has a section
    17 of a larger diameter, with which it rests against the gasket 18, and the horizontal channel 12 is immediately under this section 17.
    Since the horizontal channel 12 has a rectangular cross section when moving the pusher 9 down, this channel remains closed by a gasket.
    18 longer time than the channel of circular cross section.
