Abstract (en)
The control circuit (C) switch is operated by the displacement of a diaphragm (8) subjected to the opposing forces of a spring (11) and of the pressure of the liquid in the delivery pipe (4) of the pump (2). The diaphragm is fitted so as to be displaced beyond the position which corresponds to closing of the circuit (C). Water supply installation. <IMAGE>
Abstract (fr)
L'interrupteur du circuit de commande (C) est manoeuvré par le déplacement d'une membrane (8) soumise aux forces antagonistes d'un ressort (11) et de la pression du liquide dans le conduit de refoulement (4) de la pompe (2). La membrane est montée de manière à se déplacer au-delà de la position qui correspond à la fermeture du circuit (C). Installation d'alimentation en eau.
