   Die Anwendung des Kniehebelmechanismus t, h, h hat den Vorteil, dass die wirksame Komponente des auf die Klappen p, p wirkenden Kolbendruckes mit der Zunahme des beim Schliessen der Klappen auftretenden Wasserdruckes ungefähr proportional wächst, so dass der Querschnitt des Druckzylinders o bei gegebenem Druck ökonomisch dimensioniert werden kann. Der Kniehebelmechanismus bildet auch eine selbsttätige Sperre gegen die öffnende Wirkung des Wasserdruckes, da die beiden Kniehebelarme t, h in geschlossener Stellung der Klappen p, p sich in eine senkrecht zur Längsschiffsebene liegende Gerade einstellen, und die auf beide Klappen öffnend wirkenden Druckkomponenten sich daher gegenseitig aufheben. 



   Der   Kniehebelmechanismus kann auch   nach der in Fig. 4 gezeigten Konstruktion aus-   geführt   werden, bei der die Anlenkungspunkte   2,   2 der   Kniehebelarme   3, 3 nicht zusammenfallen, sondern seitlich von der Druckstange t, und zwar derart angeordnet sind, dass die Arme   3,.     3   sich kreuzen. 



   Durch diese Wahl der   Antekungspunkte   wird bewirkt, dass die Arme 3, 3 schon bei Beginn der Schliessbewegung einen grösseren Winkel gegen die Klappen p, p einschliessen, und die Kraft-   richtung   in dieser   Bewegungsphase   eine günstigere ist, als bei der erstbesehriebenen Anordnung.

   The use of the toggle mechanism t, h, h has the advantage that the effective component of the piston pressure acting on the flaps p, p increases approximately proportionally with the increase in the water pressure occurring when the flaps are closed, so that the cross-section of the pressure cylinder o at a given pressure can be economically dimensioned. The toggle mechanism also forms an automatic lock against the opening effect of the water pressure, since the two toggle arms t, h in the closed position of the flaps p, p align themselves in a straight line perpendicular to the fore and aft plane, and the pressure components that open on both flaps are therefore mutually exclusive cancel.



   The toggle lever mechanism can also be designed according to the construction shown in FIG. 4, in which the articulation points 2, 2 of the toggle lever arms 3, 3 do not coincide, but are arranged to the side of the push rod t in such a way that the arms 3, . 3 cross each other.



   The effect of this choice of the anchoring points is that the arms 3, 3 enclose a larger angle against the flaps p, p at the beginning of the closing movement, and the direction of force in this movement phase is more favorable than in the case of the first-level arrangement.
