Abstract

Die Erfindung betrifft ein Zumischsystem für Feuerlöschanlagen zur Erzeugung eines Löschmittel-Löschmitteladditiv-Gemischs (Premix) durch Zumischen eines Löschmitteladditivs, insbesondere eines Schaummittels, zu einem Löschmittel, insbesondere Wasser, mit einem von dem Löschmittelstrom antreibbaren Motor (1), einer von dem Motor (1) antreibbaren Zumischpumpe (20), einer Zumischleitung und einer Löschmitteladditivleitung. Um bei einem solchen Zumischsystem die Betriebssicherheit zu erhöhen, werden verschiedene Maßnahmen vorgeschlagen: So kann die Außenwand des Arbeitsraumes (10) des als Rotationsmotor ausgestalteten Motors (1) die Form einer logarithmischen Spirale aufweisen. Außerdem kann die Wand des Drainagegehäuses (5) des als Rotationsmotor ausgestalteten Motors (1) einen Durchgangsschlitz (12, 13) zum Einlass und/oder Auslass des Löschmittels aufweisen. Weiterhin kann der Eingang (22) der Zumischpumpe (20) derart angeordnet sein, dass das Löschmitteladditiv im Wesentlichen parallel zur Bewegungsrichtung (27, 28, 29) der Kolben (24, 25, 26) der Zumischpumpe (20) in diese strömen kann. Schließlich kann die Zumischpumpe (20) ein integriertes Entlastungsventil (30) aufweisen.
