Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf die bekannten Vorrichtungen zum Vermindern der Reibung zwischen Schiff und Wasser durch Bildung eines das Schiff umgebenden Luftkissens. Bei Stillstand des Gebläses dringt bei den bekannten Einrichtungen das Außenwasser in die Luftleitungen ein und letztere werden durch die im Wasser befindlichen Unreinlichkeiten aller Art verschmutzt und gegebenenfalls verstopft. Zweck der Erfindung ist, dieses Verstopfen zu verhüten.The invention relates to known devices for reducing friction between ship and water through the formation of an air cushion surrounding the ship. When the fan stops, the outside water penetrates in the known devices the air ducts and the latter are caused by the impurities in the water of all kinds soiled and possibly clogged. The purpose of the invention is to prevent this clogging.

Die Erfindung besteht darin, daß die außenbords liegenden Austrittsöffnungen für die Luft durch wasserdicht schließende, bewegliehe oder biegsame Klappen von außen abgedeckt werden.The invention consists in that the outboard outlet openings for the Air covered from the outside by watertight, movable or flexible flaps will.

Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. An embodiment of the invention is shown in the drawing.

Fig. ι veranschaulicht einen Teil der Schiffshaut mit der schematischen Anordnung des Luftverteilungssystems, und Fig. 2 in größerem Maßstabe einen Schnitt durch eine abgedeckte Luftaustrittsöffnung.Fig. Ι illustrates part of the ship's skin with the schematic arrangement of the air distribution system, and FIG. 2 shows, on a larger scale, a section through a covered air outlet opening.

Die Luftkompressoren 1 befördern in der bekannten Weise die Luft in die Verteiler 2, aus denen sie durch die Öffnungen 3 austritt. Die Öffnungen 3 sind von außen durch wasserdicht schließende, beweglich gelagerte oder biegsame Klappen 4 (Fig. 2) abgedeckt, die die Öffnungen 3 gegen den Eintritt des Wassers abschließen, dagegen beim Arbeiten der Gebläse unter der Einwirkung des Druckes der Luft sich öffnen und der Luft den Austritt gestatten. Beim Stillstand der Gebläse legen sich die Klappen dicht auf und verhindern so nicht nur den Eintritt von Seewasser und Verunreinigungen in die Leitungen, sondern machen es auch den im Wasser befindlichen Lebewesen aller Art unmöglich, in die Leitungen zu gelangen.The air compressors 1 convey the air into the distributor 2 in the known manner, from which it emerges through the openings 3. The openings 3 are through from the outside watertight, movably mounted or flexible flaps 4 (Fig. 2) covered, which close the openings 3 against the entry of water, however, when working the fan will open under the action of the pressure of the air and the air will exit allow. When the fan comes to a standstill, the flaps close tightly and prevent them so not only the entry of sea water and impurities into the pipes, but also the im Living organisms of all kinds in water are impossible to get into the pipes.
