Bei jenen Metallstopfbüchsenpackungen, bei denen, wie aus Fig. ι ersichtlich, geschlitzte Ringe α α verwendet werden, die an ihrer äußeren Mantelfläche kegelig geformt sind und von einem trichterförmigen Einsatze b umfaßt werden, auf dessen freie untere Ringfläche ot der Dampf im Sinne des Pfeiles / nach aufwärts schiebend wirkt, erfolgt das Anziehen der kegeligen Ringe a q dadurch,In those metal gland packs in which, as can be seen from Fig. Ι, slotted rings α α are used, which are conical on their outer surface and are surrounded by a funnel-shaped insert b , on the free lower ring surface ot the steam in the direction of the arrow / pushes upwards, the tapered rings aq are tightened by
ίο daß der Druck der Brille f durch passende Vorsatzstücke c auf die Ringe α übertragen wird. . ■ίο that the pressure of the glasses f is transferred to the rings α through suitable attachments c. . ■
Beim Betriebe tritt aber zu dem- durch die Brille f übertragenen Drucke noch jener hinzu, welcher, wie eingangs erwähnt, dadurch entsteht, daß der Trichter b durch den auf seine untere Stirnfläche mim Sinne des Pfeiles / wirkenden Dampfdruck auswärts gedrückt wird; die geschlitzten kegeligenIn operation, however, in addition to the pressure transmitted through the glasses f , there is also that which, as mentioned above, arises from the fact that the funnel b is pressed outwards by the steam pressure acting on its lower end face in the direction of the arrow /; the slotted conical
ao Ringe α α werden hierdurch noch stärker zusammengedrückt. ao rings α α are thereby compressed even more.
Dieses durch den Dampfdruck bewirkte Zusammendrücken der Ringe ist zwar bis zu einem gewissen geringen Grade willkommen, weil hierdurch die durch die Erhitzung der Ringe ä bewirkte Ausdehnung derselben aufgehoben wird, im übrigen wirkt es aber störend, weil die Ringe α an die Kolbenstange mehr, als zur Abdichtung nötig wäre, angedrückt werden, wodurch das Auftreten unnötiger Reibungsarbeit und allzu große Abnutzung der Ringe α und der Stange ν verursacht wird.This caused by the vapor pressure compressing the rings is indeed to welcome to a certain small degree, because in this way the like due to the heating of the rings caused expansion of the same is lifted, but otherwise it has a disturbing effect, because the rings α to the piston rod more than for sealing would be necessary to be pressed, whereby the occurrence of unnecessary frictional work and excessive wear of the rings α and the rod ν is caused.
Um nun dieses durch das Auswärtstreiben des Trichtereinsatzes b erfolgende Zusammenziehen der kegeligen Ringe α α einerseits nicht gänzlich unmöglich zu machen, andererseits aber nicht über ein gewisses Maß anwachsen zu lassen, wird, wie aus Fig. 2 ersichtlich, nach der Erfindung das auf die geschlitzten Ringe α α wirkende Vorsatzstück w an seiner' äußeren Mantelfläche bei % derart kegelig geformt, daß es sich gegen die kegelige Innenfläche des Einsatzstückes b legt und gegen dieses in der Weise wirkt, daß dessen Aufwärtsbewegung nur in dem Maße erfolgen kann, als das Vorsatzstück n> in den Trichter b einzudringen vermag.In order to not make this contraction of the conical rings α α entirely impossible due to the outward driving of the funnel insert b on the one hand, but on the other hand not to allow it to grow beyond a certain extent, according to the invention, the slotted one is, as can be seen from FIG Rings α α acting attachment w on its' outer surface at % shaped conical in such a way that it lies against the conical inner surface of the insert b and acts against this in such a way that its upward movement can only take place to the extent that the attachment n > is able to penetrate into the funnel b.
Um dem Auswärtsgleiten des Trichters b jedoch nicht allzu großen Widerstand entgegenzusetzen, wird an der Stirnfläche des Vorsatzstückes w in an sich bekannter Weise eine Rinne d ausgenommen, so daß die kegelig gestaltete Außenwand ^ etwas nachgeben kann.In order not to oppose too much resistance to the outward sliding of the funnel b, however, a groove d is cut out on the end face of the attachment w in a manner known per se, so that the conical outer wall ^ can yield somewhat.
