Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf eine Kolbenoder Stopfbüchsendichtung zum Gebrauch bei Dampf, Wasser, Luft oder einem anderen Triebmittel, bei welcher in einem freien Druckräume durch das Triebmittel auf seitliche Lippen Druck ausgeübt wird, um diese dicht an die Flächen anzudrücken, gegen welche die Dichtung angewendet werden soll.The invention relates to a piston or gland seal for use at Steam, water, air or another propellant in which in a free pressure space pressure is exerted by the propellant on the lateral lips in order to press them tightly against the surfaces against which the Seal should be applied.
Die Erfindung hat die Schaffung eines Mittels zum Zweck, um das übermäßige Zusammenpressen während des Gebrauches zu verhindern und so die Beseitigung der Wirkung des erwähnten Druckraumes zu vermeiden.The invention seeks to provide a means of relieving excessive compression to prevent during use and thus to avoid the elimination of the effect of the aforementioned pressure chamber.
Gemäß der Erfindung ist daher in oder zwisehen den Dichtungslippen eine vorstehende Rippe von starrer Beschaffenheit vorgesehen, die mit der nächsten Packungslage in Berührung kommen soll, um so das Aufschließen der Lippengruppen oder das Zusammendrücken der Druckräume zwischen der Rippe und den Lippen zu verhindern.According to the invention, there is a protruding one in or between the sealing lips Rib of a rigid nature is provided, which is in contact with the next layer of packaging should come, so the unlocking of the lip groups or the compression of the pressure spaces between the rib and the To prevent lips.
Gemäß der Erfindung kann die Rippe aus einem Stück mit den Dichtungslippen bestehen, oder sie kann einen besonderen Mittelteil zwisehen letzteren bilden. Der Dichtungskörper besteht in letzterem Falle aus drei Teilen, aus dem Mittelteil und den beiden seitlichen, durch Metallstifte gehaltenen Lippenteilen.According to the invention, the rib can be made in one piece with the sealing lips, or it can form a special middle section between the latter. The seal body in the latter case consists of three parts, the middle part and the two lateral parts Metal pins held lip parts.
Die Rippe kann an der Ober- und Unterseite der Dichtung vorstehen.The rib can protrude from the top and bottom of the seal.
Die Erfindung ist auf der Zeichnung beispielsweise veranschaulicht.The invention is illustrated in the drawing, for example.
Fig. ι zeigt eine Dichtung, bei der die Rippe nur auf einer Seite vorsteht und mit den Dichtungslippen ein Stück bildet,Fig. Ι shows a seal in which the rib protrudes only on one side and with the Forming one piece of sealing lips,
Fig. 2 eine Dichtung, bei der die Rippe getrennt hergestellt ist und oben und unten über die Dichtungslippen hervorragt.Fig. 2 shows a seal in which the rib is made separately and above and below protrudes over the sealing lips.
Zur Herstellung einer Dichtung a (Fig. 1) werden Stofflagen in Faltungen aufgerollt und durch Gummi verklebt, so daß dabei die Lippen b und die Rippe c gebildet werden. Der die Rippe bildende Teil kann auch allein hergestellt, auf die erforderliche Härte auf passende Weise gebracht, und die Dichtungsteile können sodann daran angeklebt werden. Bei der Abänderung nach Fig. 2 ist der Rippenteil besonders hergestellt und gehärtet. Er besitzt rechteckigen Querschnitt. Die Rippe c ragt oben und unten über die Dichtung hervor. Die Lippenteile δ können durch Stifte iZ oder in anderer Weise mit dem Rippenteil verbunden werden.To produce a seal a (Fig. 1), layers of fabric are rolled up in folds and glued by rubber, so that the lips b and the rib c are formed. The part forming the rib can also be made alone, suitably made to the required hardness, and the sealing parts can then be glued to it. In the modification of Fig. 2, the rib part is specially made and hardened. It has a rectangular cross-section. The rib c protrudes above and below the seal. The lip parts δ can be connected to the rib part by pins iZ or in some other way.
Die Dichtung kann aus beliebigem Stoffe hergestellt sein.The seal can be made of any material.
