A pump control apparatus includes a pump (13) coupled at an inlet to a water source (14) and at an outlet to a first dispensing valve (18) and a carbonator (15) via a check valve (16). A power source (12) is coupled to the pump (13), and a controller (11) regulates the delivery of power from the power source (12) to the pump (13). Responsive to a fill signal received from the carbonator (15), the controller (11) activates the power source (12) to deliver power to the pump (13) at a first predetermined level. Alternatively, the controller (11) activates the power source (12) to deliver power to the pump (13) at a second predetermined power level in response to a dispense signal received from the dispensing valve (18).

On décrit un appareil de commande de pompe qui inclut une pompe (13) couplée, au niveau d'un orifice d'entrée, à un poste d'eau (14) et, au niveau d'un orifice de sortie, à une soupape de distribution (18) et un carbonateur (15), par l'intermédiaire d'un clapet de non-retour (16). Une source d'énergie (12) est reliée à la pompe (13) et un servo-régulateur (11) régule la distribution d'énergie de la source d'énergie (12) à la pompe (13). En réaction à un signal de remplissage reçu du carbonateur (15), le servo-régulateur (11) active la source d'énergie (12) pour distribuer de l'énergie à la pompe (13) à un premier niveau de puissance préétabli. Dans une autre forme d'exécution, le servo-régulateur (11) active la source d'énergie (12) pour distribuer de l'énergie à la pompe (13) à un deuxième niveau de puissance préétabli, en réponse à signal de distribution reçu de la soupape de distribution (18).
