Description

Bei vielen Schiffen ist es erwünscht, denFor many ships it is desirable to have the

abfließenden Schraubenstrahl mehr oder weniger nach oben abzulenken, z. B. zum Zwecke des Schönens von Kanalsohlen undto deflect the outflowing screw beam more or less upwards, e.g. B. to Purposes of beautifying sewer bottoms and

S Böschungen.S embankments.

Es ist bekannt, zu diesem Zwecke zusätzliche Platten vor oder hinter der Schraube anzuordnen. Diese haben jedoch den Nachteil, daß meist der Wirkungsgrad der Schraube hierdurch beeinträchtigt wird und 'daß sich im Fahrwasser schwimmende Fremdkörper, wie Zweige, Baumwurzeln u. dgl., an diesen Platten festsetzen können. ,It is known to have additional plates in front of or behind the screw for this purpose to arrange. However, these have the disadvantage that mostly the efficiency of the screw is thereby impaired and 'that in the fairway floating foreign bodies, such as Branches, tree roots and the like, can attach to these plates. ,

Die Erfindung besteht darin, durch eine genügend breite, sanft nach oben gewölbte Fläche hinter der Schraube den Schrauibenstrahl nach oben abzulenken. Hierbei wird die Eigenschaft der Flüssigkeitsstrahlen ausgenutzt, sich weitgehenden Führungsflächen anzuschmiegen.The invention consists in a sufficiently wide, gently curved upwards The surface behind the screw deflect upwards. The property of liquid jets is used here, to hug extensive guide surfaces.

Die Abb. 1 und 2 zeigen eine derartige AüsfÜhxuingsform für ein düsenloses Fahrzeug. Die Abb. 3 und 4 zeigen die erfindungsmäßige Einrichtung bei einem Schiraubenfahrzeug mit Düse.Figs. 1 and 2 show such an AüsfÜhxuingsform for a jet-less vehicle. Figs. 3 and 4 show the device according to the invention in a ski pumping vehicle with nozzle.
