Bei Erhöhung des Kühlwasserdruckes (P2) auf etwa 11 bar wird die untere Düse (5) entgegen dem Dampfdruck (D) geöffnet und Kühlwasser spritzt aus.When the cooling water pressure (P2) is increased to approximately 11 bar, the lower nozzle (5) opened against the steam pressure (D) and Cooling water splashes out.
A2 > A1 und die wirksame Druckfläche des Kühlwassers ist AR. Zum Öffnen der Düse(n) (5) muß P2 >> P1 sein. A2> A1 and the effective pressure area of the cooling water is AR. To open the nozzle (s) (5), P2 >> P1 must be.
