Abstract

Le dispositif est situé au carrefour de quatre voies desservant les zones d'aspiration 2, de refoulement 3 et les deux volutes 4 et 4". Il comporte deux clapets 8, 9 montés libres sur un axe 20, solidaire d'un tournant 10 et d'un bouton de commande extérieur au corps de pompe. Les clapets dont la position dépend de la pression appliquée à l'encontre d'un ressort 23 assurent l'alternance du flux venant de la volute active, en transit vers le refoulement. La position du tournant contrôle la liaison aspiration-refoulement et fait fonction de variateur de débit par réglage commun sur les deux pompes. Applicable aux pompes jumelées, spécialement aux pompes d'accélération pour chauffage central.The device is located at the crossroads of four channels serving the suction 2, delivery 3 and two volutes 4 and 4 "zones. It comprises two valves 8, 9 mounted freely on an axis 20, integral with a turn 10 and a control button external to the pump body The valves, the position of which depends on the pressure applied against a spring 23, alternate the flow coming from the active volute, in transit towards the discharge. Rotary position controls the suction-discharge connection and acts as a flow variator by common adjustment on the two pumps Applicable to twin pumps, especially to central heating acceleration pumps.
