Description

  

   <Desc/Clms Page number 1> 
 



  Membransender. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Das Rohr 6 kann mit Vorteil durch eine schmale Verstärkungsrippe   8   gestützt werden, die von dem Rohr bis zu der dem Stutzen diametral entgegengesetzten Seite des Gehäuses 3 reicht. Um den Ring 2 festzuhalten, damit er sich nicht bei den Vibrationen löst, kann er mit einer Aussparung o. dgl. versehen werden, in welche das freie Ende einer am Gehäuse 3 mittels Schrauben 9 o. dgl. befestigten Feder 10 eingreift, so dass die Drehung des Ringes 2 verhindert wird. 



   In Fig. I bezeichnet 11 ein in der Wand des Ausströmungsraumes vorgesehenes Loch, welches zur Ableitung des Kondenswassers dient, z. B. wenn Dampf als Treibmittel verwendet wird. 



   Ausserhalb der Membran kann ein nicht dargestellter Deckel angebracht werden, um die Membran zu   schützen.   Dieser Deckel ist zweckmässigerweise mit Aussparungen oder Perforierungen versehen, um die Schallwellen wirksam durchzulassen.

 <Desc / Clms Page number 2>

 



   The pipe 6 can advantageously be supported by a narrow reinforcing rib 8 which extends from the pipe to the side of the housing 3 diametrically opposite the socket. In order to hold the ring 2 so that it does not come loose during the vibrations, it can be provided with a recess or the like, into which the free end of a spring 10 attached to the housing 3 by means of screws 9 or the like engages so that the rotation of the ring 2 is prevented.



   In FIG. B. when steam is used as a propellant.



   A cover (not shown) can be attached outside the membrane to protect the membrane. This cover is expediently provided with recesses or perforations in order to allow the sound waves to pass through effectively.

Claims (1)

PATENT-ANSPRUCH : Membransender mit einer gegen die Austrittöffnung des Treibmittel-Zuführungsrohres anliegenden Membran und einem senkrecht zur Membran im Gehäuse angeordneten als Auslassrohr dienenden Schalltrichter, dadurch gekennzeichnet, dass das Zuführungsrohr durch die Wandung des Gehäuses zwischen der Membran und dem Schalltrichter hindurchgeht und derart schräg gegen die Membran gerichtet ist, dass sein in das Gehäuse hineinragendes Ende unmittelbar in der Mitte der Membran mündet. PATENT CLAIM: Membrane transmitter with a diaphragm resting against the outlet opening of the propellant supply pipe and a horn which is arranged perpendicular to the diaphragm in the housing and serves as an outlet pipe, characterized in that the supply pipe passes through the wall of the housing between the diaphragm and the horn and is thus directed obliquely against the diaphragm is that its end protruding into the housing opens directly in the middle of the membrane.
