    A control device associated with a pneumatically-driven demand pump comprising a valve system which shuts off the gas which drives the pneumatic pump in response to a pressure-sensitive diaphragm which detects variations in pressure in the fluid output from the pump. The pressure-sensitive diaphragm serves the dual function of suppressing surges of liquid flow from the pump and stopping the pump when the liquid pressure drops below a predetermined minimum by closing a valve to shut off the gas.

    The invention relates to a dosing technique and can be used to dispense beverages with their subsequent mixing. The purpose of the invention is to increase reliability in operation, which is achieved by including a mechanism for controlling fluctuations in a syrup connected to a pump drive.
    Figure 1 shows the proposed system, the overall look; Fig. 2 is a variation of the device for regulating the supply of syrup.
    The proposed system consists of dispensing valves 1 connected to them via pipeline 2 for pneumopump syrup 3, which can be of the diaphragm type and contains shaft 4 and diaphragms 5 located at its ends dividing chambers 6 into two cavities into which
    alternately, through a reversing valve 7, air is supplied through pipelines 8, devices 9 for regulating the supply of syrup, including a mechanism for controlling syrup fluctuations mounted on pipe 2 for syrup, which represents an elastic element 10 connected to it and located on the air supply pipe 8, a valve 11 for regulating the air supply, and a spring 12, wherein the elastic element 10 can be made in the form of a membrane 13 and connected to the valve 11 by means of a piston 14 displaced p chnym drive (15 and source 16 may comprise a plurality of syrup reservoirs 17 groups.
    The system works as follows.
    The syrup is supplied to the chambers 6 of the pneumatic pump 3 via the inlet check valves 18 from the source 16 of the syrup. The air for driving the pneumatic pump 3 is alternately supplied to the inner sides of the diaphragms 5 by means of the reversing valve 7 through the pipes 8. As the pneumatic pump 3 reciprocates, the syrup from the chambers 6 is alternated through the orifice valves 19 and through the control mechanism the syrup fluctuates as the pressure changes to the dispensing valves 1; If the pressure of the syrup in line 20 drops below a certain level,

    The other element 10 closes the valve 11 to regulate the air supply, the air supply compartment to the pneumatic pump 3 and stop it. The elastic element 10 also calms the flow of syrup from the line 20 to the dispensing valves 1.
    The mechanism for controlling fluctuations of the syrup with a change in pressure works as follows. The syrup through the inlet 21 enters the line 20 and then through the outlet 22 to the dispensing taps 1 for mixing. . . The air that drives the pneumatic pump 3 passes into the control device 9 through the inlet 23 and is directed through the chamber 24 and the valve 11 to regulate the air supply to the outlet 25 of the second line 26. The air passes to the pneumatic pump 3 through the reversing valve 7 for In order to act on the diaphragms 5, which feed the syrup through the line 20. By means of a manual actuator 15, the piston 14 is lowered, which allows air to flow from the pneumopump 3 until the syrup pressure at the outlet is 100 It is sufficient using this shortcut to keep open uplot- tional valve member 27. The elastic element 10, when it is made in the form of a membrane 13 fixed on the piston rod, is sensitive to pressure changes inside the line 20, moves the sealing element 27. At the same time, the membrane 13, the piston 14 and the sealing element 27 are continuously shifted upwards by means of a spring 12 If the pressure inside the line 20 falls below a certain level, the spring 12 presses the sealing element 27 to the seat, section of the air flow from the inlet of the line. Thus, when the syrup flow stops, the pressure in line 20 collapses, sealing element 27 closes, and air does not flow to pneumonias 3. Depending on the cause of the pressure drop, the syrup can again flow into the suction line of pneumonias 3. To do this, manually seal 15 element 27. If the pressure of the syrup at the outlet of the pneumatic pump 3 is high enough to hold the sealing element 27 open 1m, the manual actuator 15 is released.
