Bei fallender Entnahme geht die Wirkungsweise in umgekehrter Folge vor sich. Das Ventil A schliesst sich infolge seiner stärkeren Belastung zuerst und das Wasser geht nur noch durch die Abzweigleitung i zum Hauptmesser. Tritt bei noch weiter sinkender Entnahme der Druckausgleich unter dem Kolbon k ein, so sinkt derselbe infolge seines Eigengewichtes auf seinen Sitz herab und gibt den Zugang o zum Nobenmesser frei. Zu gleicher Zeit findet, da das den Nebenmosser passierende Wasser nicht mehr auf das Ventil B wirken kann, hier ein Druckausgleich statt und sinkt dasselbe, den Hauptmesser abschliessend, in seine Ruhestellung.
Zur Regelung dos Wasserquantums, bei welchem die Umschaltung von dem kleinen auf den grossen Messer und umgekehrt erfolgen soll, dient die Drosselscheibe p mit den Löchern l. Entsprechend der Drosselung der korrespondierenden Löcher 1, welche sich in der Drosselscheibe und im oberen Flansche des Kolbens k befindet, tritt der Überdruck unter dem Kolben k bei einem grösseren oder geringeren Wasserquantum ein und hiedurch auch die Umschaltung von dem kleinen auf den grossen Messer und umgekehrt.

With decreasing withdrawal, the mode of action proceeds in reverse order. Valve A closes first due to its heavier load and the water only goes through branch line i to the main knife. If the pressure equalization occurs under the piston k as the withdrawal continues to fall, the latter sinks down on its seat as a result of its own weight and enables access o to the Nobenmesser. At the same time, since the water passing the secondary mosquito can no longer act on valve B, pressure equalization takes place here and the same sinks, closing the main knife, into its rest position.
The throttle disk p with the holes l is used to regulate the water quantity, in which the switchover from the small to the large knife and vice versa is to take place. Corresponding to the throttling of the corresponding holes 1, which are located in the throttle plate and in the upper flange of the piston k, the overpressure under the piston k occurs when the water quantity is larger or smaller, and thereby also the switchover from the small to the large knife and vice versa .
