Description

Hahn mit Ölkammer Die Erfindung bezieht sich auf einen Hahn mit Ölkammer und in dieser geführtem; unter dem Druck der Leitungsmittel stehendem Kolben zur Zuführung des Schmiermittels zu den Reibflächen des Kükens.Cock with an oil chamber The invention relates to a cock with an oil chamber and in this run; under the pressure of the conduit means to the piston Supply of the lubricant to the friction surfaces of the plug.

Das Neue besteht darin, daß die Ölkammer im Hahnküken selbst, und zwar am weiten Ende desselben angeordnet ist und daß diese Kammer durch eine Bohrung mit dem Durchlaß des Kükens in Verbindung steht.The new thing is that the oil chamber in the cock plug itself, and although it is arranged at the wide end of the same and that this chamber through a bore communicates with the passage of the chick.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigen Abb. i einen senkrechten Mittelschnitt durch den Hahn, Abb. 2 das Küken dazu im Schnitt nach der Linie A-B der Abb. 3, Abb. 3 die Unteransicht des Kükens.In the drawing, the invention is shown in an exemplary embodiment, Fig. 1 shows a vertical middle section through the tap, Fig. 2 the Chick for this in section along the line A-B of Fig. 3, Fig. 3, the bottom view of the Chick.

Das Küken a sitzt in einem mit Deckel b verschließbaren Gehäuse c und wird unmittelbar durch eine um das abgesetzte weite Kükenende liegende Druckfeder d auf die Dichtungsflächen niedergehalten. Am weiten Ende besitzt das Küken a eine Kammer g, die durch eine Bohrung k mit dem Durchlaß e des Kükens verbunden ist und zur Aufnahme von Schmiermitteln dient. Mit dem weiten Ende ragt das Küken in eine im Gehäusedeckel vorgesehene Schmiermittelvorratskammer i. In der Kammer g verschiebt sich ein Kolben k, der das Küken nach dem Durchlaß e hin abdichtet. Unter dem Druck des durch die Bohrung h in die Kammer g einströmenden Leitungsmittels, das bei geschlossenen Hahn über den Durchlaß e und die Bohrung f zum Kolben dringt, wird das Schmiermittel den Reibflächen des Kükens zugeführt, die durch Kanäle 1, in mit der Schmiermittelkaminer i bzw. g verbunden sind. Auch bei geöffnetem Hahn tritt zwischen dem Kolben h und der dem Leitungsinitteldruck ausgesetzten Flächen des Durchlasses e Spannung ein, durch die ein Selbstdichten und Selbstschmieren des Kükens bewirkt wird.The plug a sits in a housing c that can be closed with a cover b and is held down directly on the sealing surfaces by a compression spring d located around the remote end of the plug. At the wide end, the plug a has a chamber g which is connected to the passage e of the plug through a bore k and serves to receive lubricants. The wide end of the plug protrudes into a lubricant storage chamber i provided in the housing cover. A piston k, which seals the plug towards the passage e, moves in the chamber g. Under the pressure of the line medium flowing through the bore h into the chamber g, which, when the cock is closed, passes through the passage e and the bore f to the piston, the lubricant is supplied to the friction surfaces of the plug, which through channels 1, in with the lubricant chamber i and g are connected. Even when the tap is open, tension occurs between the piston h and the surface of the passage e which is exposed to the central pressure of the line, causing the plug to self-seal and self-lubricate.

Das Öffnen und Schließen des Hahnes erfolgt mittels eines Stiftes o. dgl., der in die Bohrung t eines über das Gehäuse hervorstehenden runden Zapfens s des Kükens eingeführt wird.The cock is opened and closed by means of a pin o. The like. In the bore t of a round pin protruding from the housing s of the chick is introduced.
