    The speed signal sensor is made in the form of a pressure signal generating unit 7 forming the signals proportional to the speed. The pressure signal generating unit 7 (Fig. 1) is made in the form of an additional self-closed circuit for the circulation of fluid consisting of a running wheel 8, not driven by a sprayer and a pump 9 o

The handheld load sensor 25 has a loaded upper. with a disk 24, a cup spring 28, on which a compression spring 29 is supported. Its prestressing can be carried out using a handwheel 30 with a threaded axis 31 and an axially displacing disk 32o. To unload the compression spring 29, the spring 28 can be discharged from the upper disk 24, for example, due to the fact that the eccentric valve 13 pin 33 by lowering the handle 34 downward.

    The piston 14 is equipped with a side V-shaped recess 35. In the hole 36 of this recess 35 of the housing 13 includes a control unit 37, which controls the pressure regulator 2.
    The control unit 37 has a housing 38 in which there is a two-piece ball valve, made in the form of a ball 39, upper AO and lower 41 conical valve seats. A cavity 42 is formed under the lower valve seat 41. A vertical control rod 43 rests on the ball 39 centrally. In this case, the upper valve seat 40 is formed on the lower end side of the hollow screw 44, and the external thread of the hollow screw 44 fits tightly to the threaded hole of the housing 38. By unscrewing or screwing in, the relative position of the upper valve seat 40 can be adjusted. The hollow screw 44 is fixed in position by the nut 45.
    The hollow screw 44 has a central hole 46, the diameter of which is chosen in such a way that an annular gap 47 is formed around the outer shell of the control rod 43, which is connected to the zone of the upper seat 40 of the valve.
    An inlet 48 for a control medium enters cavity 42, which in this case is connected via a pipe 49 to a compressed air source. And the outlet 50 of the control unit 37 is connected to the controller via a pipe 51. the pressure of the spray circuit.
    The upper free end of the control rod 43 interacts with the upper horizontal surface of the V-shaped recess 35 of the piston 14. Accordingly, when the piston 14 moves downwards, the control rod 43 shifts the ball 39 down and presses it to the lower seat 41 of the valve. Thus, the ball 39 closes the channel of the incoming compressed air. And the pressure prevailing before in the pipe 51 can then be vented through the annular gap 47, since the upper valve seat 40 is open.
    Sprayer works as follows.

    The pressure signal generating unit 7 is transmitted via control line 12 to control unit 6, which affects the pressure regulator 2 of the spray liquid supply circuit.
    As a result, the liquid will be sprayed in proportion to the speed of movement of the aggregate and, consequently, to the area of the surface to be treated.
    If the operating pressure is less than the initially specified pressure value, then in the pressure signal pipe 17, and therefore, in the lower chamber 16 of the control unit 6, the pressure will decrease. This will cause the pressure, initially set on the load hand-held sensor 25, as well as the pressure acting through the control pipeline 12 on the load adder 21, displaces the piston 14 downwards. The adjustment is carried out by means of the adjustment block 37 - in the manner described, i.e. the ball 39 locks the lower valve seat 41 and through the outlet 50 and the annular gap 47, which is under pressure in the pipe 51, the air is released.
    Since, in this case, the pressure regulator 2 of the spray liquid supply circuit receives a lower pressure through the control pipe 51, the pressure in the pressure pipe 4 is raised by the pressure regulator 2. In this case, the pressure regulator 2 is a negative control valve, which, in a known manner, by using a correspondingly lower control pressure always provides greater pressure of the spray liquid.
    If the operating pressure is higher than the initially prescribed pressure value, then the piston 14 moves upward, while the control rod 43 causes the ball 39 to rise upwards. At the same time, the ball 39 is pressed against the valve upper seat 40 due to compressed air entering the inlet 46, as a result of which the compressed air makes way through the inlet 50. As the regulating pressure in the pipe 51 increases, the pressure regulator 2 controls the fluid supply circuit for spraying and lowers fluid pressure,
    As a pressure regulator 2, if necessary, a positive control regulating valve can also be used, or the present valve can be installed in a housing with a 180 ° rotation.
    Figs 4 and 5 show an example of sprayer release for spraying a liquid under constant pressure.
    The design in accordance with, 4 differs from the solution in accordance with FIG. 1 in that the actual basic solution is stored here in the sprayer tank 3 or, if supplied in liquid form, the chemical reagent itself. The constant operating pressure that is required for spray heads (not shown) of frame 5 with spray tips is provided by an additional special circuit for circulating Cyst water, which consists of a reservoir 52, a pump 53 and a pressure regulator 54.
    Setting the working pressure in frame 5 with spray tips. This is carried out in contour type for the circulation of pure water and is essentially independent of the speed of movement of the sprayer. To the pressure pipe 55 of the circuit for the circulation of clear water is connected a pressure pipe 4 supplying the main solution, in which an additional throttling device 56 is installed, which creates a pressure drop.
    Thus, the circulation circuit of the Main solution provides the donation to the fluid circuit, which is under elevated pressure. The corresponding pressure of this fluid circuit through another diaphragm 57 separating the medium transmits the pressure signal pipe 58 to the control unit 6 designed as a pressure copier.
    FIG. 5 that the control unit 6 used in this case is different from the design in accordance with FIG. 2 in that here an inter-control load adder 21 and a cup spring 28 install another load adder 59 through an elastic membrane 60. From the design point of view of the load adder 59, it corresponds to the load adder 21. Its lower disk 61 is mounted in chamber 62 with the possibility of moving in the axial direction, into which the pressure signal pipe 58 comes out.
    When operating the sprayer in accordance with FIG. 4 and 5 on the controlled side of the control unit 6 acts on the one hand, the pressure is proportional to the velocity, and on the other hand, the pressure of the circuit for circulating pure water through the pressure signal pipeline 58. This ensures that the dosage of the chemical reagent does not depend on the corresponding pressure of the circuit for the circulation of pure water.
    The spray pressure on frame 5 with spray tips will always be constant. This contributes to the formation of always constant quality in the spray heads.
    The mechanical pressure signal generating unit 7 described in the exemplary embodiments is suitable for generating a quadratic (parabolic) function.
    The device in the off position can be adjusted using the handwheel 30 to the desired pressure (for example, based on tables or measured data).
    This pressure value for the prescribed advance rate is set when the frame 5 is turned off with the spray tips, with the help of the metering device 10. The device is thus brought to the ready state for spraying. Mentioned tuning can be carried out even on the way, following, without causing a loss of chemical reagent.
