Description

zu gleichen Teilen gemischt aus. Der Kontakt 18 ist den Magnetventilen 8 und 12 zugeordnet und bewirkt also eine Mischung von Warm- und Kaltwasser etwa im Verhältnis 2:1. Der Kontakt 20 ist ein Ausschalter, der nach jeder Betätigung eines anderen Kontaktes den Ausgangszustand mit geschlossenen Magnetventilen wieder herstellt Der Kontakt 20 kann fortfallen, wenn die Kontakte 16 bis 19 in bekannter Weise mit einer beim erneuten Drücken lösbaren Einschaltsperre versehen sind.mixed in equal parts. The contact 18 is assigned to the solenoid valves 8 and 12 and operates So a mixture of hot and cold water in a ratio of around 2: 1. Contact 20 is an off switch, which, after each actuation of another contact, the initial state with closed solenoid valves The contact 20 can be omitted if the contacts 16 to 19 are in a known position Way are provided with a switch-on lock that can be released when the button is pressed again.

Man könnte zusätzlich einen Kontakt vorsehen, der nur dem Magnetventil 12 zugeordnet ist, um die halbe Kaltwassermenge entnehmen zu können. Schließlich könnte man auch vom Rohrstutzen 3 für Warmwasser eine ein Magnetventil und eine Drossel enthaltende Umgehungsleitung zur Mischkammer ab-You could also provide a contact that is only assigned to the solenoid valve 12 to the to be able to take half the amount of cold water. Finally, you could also from the pipe socket 3 for Hot water a bypass line containing a solenoid valve and a throttle to the mixing chamber

Dann könnte man durch Anordnung weiterer Kontakte auch Schaltungen für eine Mischung von Warm- und Kaltwasser im Verhältnis 1:2, eine Wannwasserentnahme halber Menge und ein Mischungsverhältnis 1:1 mit reduzierter Menge durch-branches. Then one could also create circuits for a mixture by arranging further contacts of hot and cold water in a ratio of 1: 2, half the amount of water being withdrawn from the bath and a mixing ratio 1: 1 with a reduced quantity
