  Stopfbüchsenpackung für Gas- oder Luftverdichtungspumpen.

 poraturen besonders schwierig. Die bisher verwendeten Packungen bestehen gewöhnlich aus aufgeschnittenen   zylindrischen oder keilförmigen Ringen.   Diese werden nun bei einer Erwärmung der Stopfbüchse einseitig fest gegen die Kolbenstange gepresst und bilden, da sie sich nicht der sich ausdehnenden Kolbenstange anpassen, Fugen für den Durchtritt des abzudichtenden Mittels. Ausserdem rufen sie dabei eine Beschädigung der Kolbenstange hervor, wobei die Abdichtung noch verschlechtert wird. 



   Es sind ferner Stopfbüchsen bekannt geworden, bei welchen unaufgeschnittene Dichtungsringe mit aufgeschnittenen abwechselten. Allein auch bei diesen bestehen die oben er- örterten   Obelst11ndo. Dio   vorliegende Erfindung besteht nun in der ausschliesslichen Verwendung von geschlossenen nicht aufgeschnittenen zylindrischen Dichtungsringen, welche sich abwechselnd an die Kolbenstange und an den Stopfbüchsenhals dicht anlegen. 



   In der Zeichnung ist die neue Stopfbüchse in einem Ausführungsbeispiel dargestellt. c und e sind die beiden Ringgruppen, die Ringe o bestehen aus Gusseisen, und die Ringe e aus Weissmetall und sind mit Rilleneindrehungen versehen. Die Ringe o und   o   folgen aufeinander abwechselnd, sie haben verschiedenen Durchmesser, so dass die Weich-   metallrings e   an der Kolbenstange a abdichten, vom Stopfbüchsenhals b dagegen abstehen. Die Ringe o dichten an dem Stopfbüchsenhals b ab und stehen im Abstand von der Kolbenstange a. Diese beiden Gruppen werden durch zwei Schlussringe d und f zusammengehalten, welche sowohl an der Stange a, als auch am Stopfbüchsenhals b abdichten. 



   Infolge dieser besonderen Anordnung der Ringe ist die Packung frei beweglich und hat keinerlei Neigung sich bei   Temperaturl, nderungen   an die Stange anzupressen. Die geringe,   durch   die   Erwärmung   verursachte Längsausdehnung wird durch die Weichpackungsringe   h   ausgeglichen.

  Stuffing box packing for gas or air compression pumps.
 EMI1.1
 poratures particularly difficult. The packs used to date usually consist of cut cylindrical or wedge-shaped rings. When the stuffing box is heated, these are now pressed firmly against the piston rod on one side and, since they do not adapt to the expanding piston rod, form joints for the agent to be sealed to pass through. In addition, they cause damage to the piston rod, which makes the seal even worse.



   Stuffing boxes have also become known in which sealing rings that have not been cut open alternate with cut ones. But with these, too, the obelistions discussed above exist. The present invention now consists in the exclusive use of closed, not cut open cylindrical sealing rings, which alternately fit tightly against the piston rod and the stuffing box neck.



   In the drawing, the new stuffing box is shown in one embodiment. c and e are the two groups of rings, rings o are made of cast iron, and rings e are made of white metal and are provided with grooves. The rings o and o follow one another alternately, they have different diameters, so that the soft metal rings e seal against the piston rod a, but protrude from the stuffing box neck b. The rings o seal against the stuffing box neck b and are at a distance from the piston rod a. These two groups are held together by two locking rings d and f, which seal both the rod a and the gland neck b.



   As a result of this special arrangement of the rings, the packing can move freely and has no tendency to press against the rod when the temperature changes. The small longitudinal expansion caused by the heating is compensated for by the soft packing rings h.
