Description
Frischlufterhitzer für Kraftfahrzeuge Gegenstand des Anspruchs 3 des Hauptpatents ist ein Frischlufterhitzer für Kraftfahrzeuge mit einem zwischen dem Frischluftraum und dem abgasführenden Rohr vorgesehenen Sicherheitsraum, wobei Abgase, die bei Undichtwerden der Zwischenwandung in den Sicherheitsraum treten, durch Öffnungen im Mantel des Sicherheitsraumes ins Freie gelangen können.Fresh air heater for motor vehicles is the subject of claim 3 of the Main patent is a fresh air heater for motor vehicles with an between Fresh air room and the safety room provided for the exhaust gas pipe, whereby exhaust gases, which enter the security room if the partition wall leaks through openings can get outside in the jacket of the security room.
Die Erfindung stellt eine Verbesserung dieser Einrichtung dar, und sie besteht darin, daß der Sicherheitsraum, durch eine Leitung an die Ansaugleitung des Motors, und zwar vor dem Luftfilter und Vergaser, angeschlossen ist. Infolge des entstehenden Unterdrucks im. Sicherheitsraum werden etwa durchtretende Abgase stets nach dem Zylinder abgeleitet, und es wird somit ein übergang derselben in den zu beheizenden Raum automatisch verhindert.The invention is an improvement on this device, and it consists in that the safety room, through a pipe to the suction pipe of the engine, in front of the air filter and carburetor. As a result of the resulting negative pressure in. Exhaust gases that pass through are included in the security room always derived after the cylinder, and there is thus a transition of the same into automatically prevents the room to be heated.
In weiterer vorteilhafter Ausgestaltung der Erfindung wird in die Leitung zwischen Sicherheitsraum, und Luftfilter ein Alarmgerät einbeschaltet, welches einen etwaigen Durchtritt von Abgasen automatisch anzeigt.In a further advantageous embodiment of the invention, in the Line between the security room and the air filter switched on an alarm device, which automatically indicates a possible passage of exhaust gases.
In der beiliegenden Zeichnung ist ein Schema der Einrichtung nach der Erfindung wiedergegeben.In the accompanying drawing is a scheme of the device according to reproduced the invention.
An den Sicherheitsraum i des Frischlufterhitzers io ist eine Leitung 2 angeschlossen, die in die Ansaugleitung 3 vor denn Luftfilter 5 und Vergaser 6 mündet. Das Luftfilter 5 ist mit dem Ansauggeräuschdämpfer q. zusammengebaut. An den Motor 8 ist die Einrichtung durch den Ansaugstutzen 7 angeschlossen. In die Leitung 2 zwischen dem Sicherheitsraum i und der Ansaugleitung 3 ist ein Alarmgerät 9 eingeschaltet.There is a line to the safety room i of the fresh air heater io 2 connected to the intake pipe 3 in front of the air filter 5 and carburetor 6 flows out. The air filter 5 is connected to the intake silencer q. assembled. At the motor 8 is connected to the device through the intake manifold 7. In the Line 2 between the security room i and the suction line 3 is an alarm device 9 switched on.
Wenn ein Undichtwerden. der Wandung des Sicherheitsraumes i eintreten sollte, werden die dabei etwa durchtretenden Abgase durch die Ansaugtätigkeit des Motors mittels der Leitung 2 über das Luftfilter und den Ansauggeräuschdämpfer ¢ und 5 sowie durch den Vergaser 6 und den Ansaugstutzen 7 wieder nach dem Motor 8 abgesaugt. Auf diese Weise wird ein Durchtreten von Abgasen in den zu beheizenden Frischluftraum mit absoluter Sicherheit verhindert. Die Betätigung des Alarmgerätes q zeigt gegebenenfalls automatisch an, daß die Wandung des. Sicherheitsraumes undicht geworden ist, so daß nun die Reparatur der Wandung unmittelbar veranlaßt werden kann.When a leak. enter the wall of the security room i should, the exhaust gases that may pass through are caused by the suction of the Motor by means of line 2 via the air filter and the intake silencer ¢ and 5 as well as through the carburetor 6 and the intake manifold 7 back to the engine 8 sucked off. In this way, a passage of exhaust gases into the to be heated Fresh air space prevented with absolute certainty. The actuation of the alarm device If necessary, q automatically indicates that the wall of the security room is leaking has become, so that the repair of the wall can now be initiated immediately can.
