Description

Schallsender für Gas oder flüssige Antriebsmittel Die vorliegende Erfindung bezieht sich auf Einrichtungen zur Abgabe von akustischen Signalen in gasförmigen oder flüssigen Medien, bei welchen einer schwingenden Membran zur Erzeugung der benötigten Druckschwankungen durch Volumenänderung das flüssige oder gasförmige Antriebsmittel durch eine Düse zugeführt wird, wobei die Einschaltung ,eines elastischen, weichen Zwischengliedes aus Gummi, Leder o. dgl. vorgesehen wird, das im wesentlichen unter dem Einfluß der schwingenden Membran beansprucht wird.Sound transmitter for gas or liquid propulsion means The present The invention relates to devices for emitting acoustic signals in gaseous or liquid media in which a vibrating membrane is used to generate the required pressure fluctuations due to changes in volume be liquid or gaseous Drive means is fed through a nozzle, wherein the engagement, an elastic, soft intermediate member made of rubber, leather o. The like. Is provided, which is essentially is stressed under the influence of the vibrating membrane.

Dieses elastische Zwischenglied wird an der Austrittsstelle des Betriebsmittels angeordnet, so daß dadurch ein hartes Aufschlagen der schwingenden metallenen Membran auf die Metallteile der Mündung vermieden wird. Ein weiterer Vorteil besteht darin, daß ein dichter Düsenabschlußerreicht wird.This elastic intermediate member is at the outlet point of the operating medium arranged, so that thereby a hard impact of the vibrating metal membrane on the metal parts of the muzzle is avoided. Another advantage is that a tight nozzle seal is achieved.

In den beiliegenden Abb. i bis d. sind einige Ausführungsbeispiele dargestellt. a bedeutet in allen Zeichnungen eine Membran, b die Zuleitung und c das elastische, weiche Zwischenglied. Bei der Ausführung nach Abb. i und 2 ist darauf zu achten, daß der auf die Fläche des elastischen Zwischengliedes c wirkende Flächendruck kleiner ist als derjenige, der auf den an der Membran befestigten Düsenteil d wirkt.In the accompanying fig. I to d. are some exemplary embodiments shown. In all drawings, a means a membrane, b the supply line and c the elastic, soft pontic. In the execution according to fig. I and 2 it is important to ensure that the surface pressure acting on the surface of the elastic intermediate member c is smaller than that which acts on the nozzle part d attached to the membrane.
