The present invention concerns an air pressure actuated valve for a beverage dispenser. The dispenser includes a plurality of beverage dispensing valves mounted thereto along a front end thereof. Each valve includes an air switch that is pneumatically operable to turn its associated valve on and off. An equal plurality of air actuators are secured to an elongate panel hingedly secured to the dispenser front surface. Each air actuator includes a pressurized chamber and a pliable front surface. Flexible tubes extend between the air switches and the air actuators for communicating pneumatic pressure there between. The air actuators include a graphics layer secured to the front surfaces thereof. In operation, an air actuator is depressed manually whereby pneumatic pressure created thereby in the pressurized chamber is communicated by the tube thereof to its particular air switch. The air switch then serves to operate a solenoid of the valve with which it is associated, resulting in dispensing of the beverage. Release of pressure on the actuator front surface breaks the electrical connection stopping dispensing.

Cette invention concerne un robinet doseur à commande pneumatique pour distributrice de boisson. La distributrice comporte une pluralité de robinets doseurs montés en façade. Chaque robinet comprend un commutateur pneumatique qui commande sa fermeture et son ouverture. Un nombre égal de boutons de commande pneumatique est monté sur un panneau allongé qui est articulé en façade de la distributrice. Chaque bouton comprend une chambre sous pression et une face avant souple. Les commutateurs pneumatiques sont raccordés aux boutons de commande pneumatique par des tubes flexibles. Les boutons de commande pneumatique portent sur leur face avant souple une inscription ou un pictogramme. En enfonçant la face souple d'un bouton de commande, l'opérateur crée à l'intérieur de la chambre sous pression de celui-ci une surpression qui est transmise au commutateur pneumatique correspondant. Ce commutateur actionne le mécanisme électromagnétique du robinet doseur correspondant pour déclencher la distribution d'une boisson. Lorsque l'opérateur cesse d'appuyer sur le bouton de commande pneumatique, il ouvre le circuit d'alimentation du mécanisme électromagnétique et commande la fermeture du robinet.
