  Anordnung bei Luftvorhangtüren in Bergtunnels od. dgl. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

    -den Luftvorhang mitgerissene Luft   eine unkontrollierbare Luftströmung im Tunnelinneren hinter der Luftvorhangtüre hervorruft, ist, wie aus Fig. l hervorgeht, ein vertikaler, sich teilweise über den lichten Tunnelquerschnitt erstreckendes Stauschild 8 etwas hinter dem an der gegenüberliegenden Seite gelegenen Gebläsegehäuse 3 angebracht. 



   Dieser Schild fängt den zum Tunnelinneren gerichteten, mitgerissenen Luftstrom auf, der dadurch als Ansaugluft für die in dem daneben liegenden Gehäuse 3 untergebrachten Gebläse dient und dort in den Zeichnungen mit einem zusätzlichen Pfeil angedeutet ist. Es hat sich hiebei als zweckmässig erwiesen, die Breite des Stauschildes etwas grösser zu gestalten als den Abstand zwischen dieser Seite des Tunnels und der Schnittlinie der Luftvorhänge. 



   PATENTANSPRÜCHE : 
1. Anordnung bei Luftvorhangtüren in Bergtunnels od. dgl., bei welchen voneinander gegenüberliegenden Seitenwänden des Tunnels zwei gegeneinander und zur Tunnelmündung hin gerichtete Luftvorhänge einander treffen, wobei die Schnittlinie der Luftvorhänge der einen Tunnelwand näher liegt und der eine Luftvorhang einen kleineren Winkel mit der Tunnellängsachse einschliesst als der andere, dadurch   gekennzeichnet, dass ein sich teilweise überdenlichtenTunnelquerschnitt erstrecken-   der Stauschild (8) tunneleinwärts hinter dem den kleineren Winkel mit der Tunnellängsachse einschlie- ssenden Luftvorhang angebracht ist, und dass wenigstens eine Ansaugöffnung (5) der diesen Luftvorhang   erzeugenden Gebläseanordnung   (3) in den zwischen diesem Vorhang und dem Stauschild (8) befindlichen Tunnelbereich mündet.

  Arrangement for air curtain doors in mountain tunnels or the like.
 EMI1.1
 

 <Desc / Clms Page number 2>

    -the air curtain entrained air causes an uncontrollable flow of air inside the tunnel behind the air curtain door, as can be seen from Fig. 1, a vertical, partially extending over the tunnel cross-section extending damming plate 8 is attached a little behind the fan housing 3 located on the opposite side.



   This shield catches the entrained air flow directed towards the inside of the tunnel, which thereby serves as intake air for the blower housed in the adjacent housing 3 and is indicated there in the drawings with an additional arrow. It has been found to be expedient to make the width of the congestion shield somewhat larger than the distance between this side of the tunnel and the line of intersection of the air curtains.



   PATENT CLAIMS:
1. Arrangement for air curtain doors in mountain tunnels or the like, in which opposite side walls of the tunnel two air curtains directed towards each other and towards the tunnel mouth meet, the intersection of the air curtains of one tunnel wall being closer and one air curtain at a smaller angle with the tunnel longitudinal axis includes than the other, characterized in that a partially over the clear tunnel cross section extending congestion shield (8) is attached in the tunnel behind the air curtain enclosing the smaller angle with the longitudinal axis of the tunnel, and that at least one suction opening (5) of the fan arrangement (5) generating this air curtain 3) opens into the tunnel area located between this curtain and the congestion shield (8).
