  Bergmannslampe mit einer   Anzeigevorrichtung für Grubengase.   



   Die Erfindung bezieht sich auf eine Bergmannslampe mit einer Anzeigevorrichtung für Grubengase, bei welcher in einer durch eine poröse Platte abgedeckten Kammer infolge der Veränderungen in der Atmosphäre   Über-und Unterdruckwirkungen   hervorgerufen und durch eine   Druckmessvorrichtung   kenntlich gemacht werden. 



   Um in möglichst kurzer Zeit mit Hilfe der gleichen Vorrichtung an verschiedenen Stellen des Bergwerkes z. B. Messungen vornehmen zu können, ist gemäss der Erfindung die Diffusionskammer mit einem von aussen steuerbaren   Durchlagorgan   versehen, so dass durch   augenblicksweise Öffnung   dieses Organes ein Über- oder Unterdruck in der Diffusions-   ranimer   beseitigt werden kann, wodurch die Vorrichtung augenblicklich wieder zur Ausführung einer neuen Messung instand gesetzt wird. 



   Die Zeichnung veranschaulicht ein   Ausführungsbeispiel   der Erfindung.

   Gomäss der Erfindung ist nun der   DiSusionsraum   mit   einer Durchjtassvorrichtung   5 versehen, die durch eine Steuereinrichtung 6 von aussen geöffnet werden kann. 



   Die Wirkungsweise der Einrichtung ist folgende : Sobald infolge Eintretens von Gasen durch die poröse Platte 2 in die Diffusionskammer 1 in dieser eine Druckveränderung hervorgerufen worden ist, kann diese Druckveränderung augenblicklich dadurch beseitigt werden, dass das Ventil 5 durch die Steuervorrichtung 6 in Tätigkeit gesetzt wird.

  Miner's lamp with a display device for mine gases.



   The invention relates to a miner's lamp with a display device for mine gases, in which overpressure and underpressure effects are caused in a chamber covered by a porous plate as a result of changes in the atmosphere and are indicated by a pressure measuring device.



   To in the shortest possible time using the same device at different points in the mine z. B. to make measurements, according to the invention, the diffusion chamber is provided with an externally controllable passage organ, so that an overpressure or underpressure in the diffusion can be eliminated by momentarily opening this organ, whereby the device can immediately be used to perform a new measurement is repaired.



   The drawing illustrates an embodiment of the invention.



   1 is the diffusion chamber covered by the porous plate, 2 whose pressure
 EMI1.1
 



   According to the invention, the diffusion space is now provided with a passage device 5 which can be opened from the outside by a control device 6.



   The mode of operation of the device is as follows: As soon as a pressure change has been caused in the diffusion chamber 1 as a result of the entry of gases through the porous plate 2, this pressure change can be immediately eliminated by the valve 5 being activated by the control device 6.
