Description
Gasspürgerät Die Erfindung betrilit ein aus einer Pumpe und einem elektrisch beleuchteten Spürröhrchen bestehendes Gasspürgerät. Bei einem bekannten Gerät dieser Art ist die Beleuchtungseinrichtung außen am Gerät an-ebracht und daher bei der unvermeidlich rauhen Handliabun- leicht der BeschädÜqin- ausgesetzt.Gas detector The invention concerns a pump and a pump electrically illuminated detection tube existing gas detector. With a well-known Device of this type, the lighting device is attached to the outside of the device and therefore With the unavoidable rough handliab, easily exposed to damage.
Bekamit sind ferner Gasspürgeräte, bei denen durch ein Fenster der Behälterwandung der Farbumschla,- eines Reagenzpapieres beobachtet werden kann. Der Behälter mul,3 auf eine Pumpe aufgesetzt werden, eine Beleuchtung ist nicht- vorgesehen ', so daß im Dunkeln die Nachprüfung, ob ein Farbumschlag erfolgt ist, nicht mö-lich ist. Ferner sind auch Geräte zur Luftuntersuchung beka,mit, die ohne eine Luftfördervorrichtungarbeiten, aber eine Beleuchtungseinrichtung besitzen. Diese Geräte sind sehr umständlich in ihrem Aufbau und daher für die üblichen Gasspürzwecke ungeeignet.There are also gas detection devices with which the The container wall of the color change - of a reagent paper can be observed. The container must 3 be placed on a pump, lighting is not provided 'so that the check in the dark whether a color change has taken place, is not possible. Furthermore, devices for air testing are also available, with and without operate an air conveyor but have lighting equipment. These devices are very cumbersome in their construction and therefore for the usual gas-fueling purposes not suitable.
Die Nachteile aller dieser Geräte werden gemäß der Erfindung dadurch beseitigt, daß die Pumpe ein die Beobachtun 'g des in sie eingesetzten Spürröhrchens gestattendes Fenster besitzt und daß die Beleuchtungseinrichtun innerhalb der Pumpe angeordnet ist.The disadvantages of all these devices are eliminated according to the invention in that the pump on the Beobachtun 'g of the tracer tube inserted therein gestattendes window, and in that the Beleuchtungseinrichtun is disposed within the pump.
Die Anordnung kann dabei so getroffen C c werden ' daß die Batterie mit der Lampe und dem Schalter in einem ahnehinbaren Verlängerungsteil des Pum enzylinders unterp gebracht ist. Eine "edrän"tere Bauart be- steht darin, daß die Batterie in einer Höhlung der Kolb,enstaii-c oder des Hand-riffes derselben und die Glühbirne in einer Ansnehmung der vorderen Stirnwand des Kolbens eingesetzt ist. In der Zeichnun- ist ein Ausführun--sbeispiel der Erfindung im Längsschnitt dar-,-estellt.The arrangement can be made so C c ' that the battery with the lamp and the switch is placed in a predictable extension part of the Pum enzylinders unterp. A "edrän" direct type con- sists in the fact that the battery thereof, and the light bulb is used in a Ansnehmung the front end wall of the piston in a cavity of the piston, enstaii-c or hand reef. In the drawing, an exemplary embodiment of the invention is shown in longitudinal section.
Es ist i der Zylinder der Spürpumpr mit dem Pumpenkolben 2 und der Kolbenstange 3. In eine seitliche Fassung4 des Pumpenzylinders. i ist das Spürröhrchen 5 eingesetzt. Der der Fassung4 des Zylinders i gegenüberliegende Teil desselben ist als durchsichtiges Fenster 6 ausgebildet. An dem Pumpenzylinder i ist, beispielsweise mittels eines Schraul)stopfeiis-" ein Verlängerungsteil 8 befestigt, der die Batterie 9 und den Schalter io aufnimmt, während die Lampe ii <in der dem Spürröhrchen zugewendeten Seite des Schraubstopfens7 befestigt ist.It is the cylinder of the tracer pump with the pump piston 2 and the piston rod 3. In a lateral socket4 of the pump cylinder. i the detection tube 5 is inserted. The part of the same opposite the socket 4 of the cylinder i is designed as a transparent window 6 . An extension part 8 is attached to the pump cylinder i, for example by means of a screw plug, which accommodates the battery 9 and the switch io, while the lamp ii is attached to the side of the screw plug 7 facing the sensing tube.
