<p>Deliver system for liquids.. M--. Such as beer or other gassy drinks, in which a pre-determined quantity can be delivered by the operation of a push button; the latter is connected in an electric circuit to a dosing pump in the feed pipe for the liquid. Several delivery taps and control switches are provided in the supply pipe from the pump; the electric circuit includes a switch at each delivery point arranged so that whichever switch is actuated the others are completely isolated from the circuit unitl the delivery started by the switch is completed. The dosing pump is of the diaphragm type operated pheumatically and the switch at each delivery point is connected to a circuit which includes a solenoid valve in the pipe introducing compressed air into the pump and to an electric valve actuated by the discharge of liquid into the feed pipe. The system reduces installation costs in clubs, bars, cafes or other places in which the delivery points are not used all the time at their maximum capacity; it also assures that each pump will be used in a more regular and frequent manner and this is advantageous from the technical point of view.</p> |
