KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. MAX PUDER in BERLIN.MAX PUDER in BERLIN. entlastet ist.is relieved. Hähne gewöhnlicher Art, welche namentlich auch bei Luftdruckbremsen an den Bremscylindern und Leitungen angebracht sind, und welche dazu dienen, einen sicheren Abschlufs der Druckluft zu erzielen, öffnen sich häufig selbstthätig, wodurch Betriebsstörungen aller Art hervorgerufen werden. Der dargestellte Hahn soll diesem Uebelstande abhelfen, wobei jede aufsen liegende Versperrung, welche dem Schmutz und dem Eis, sowie überhaupt den ä'ufseren · Witterungseinflüssen ausgesetzt ist, vermieden ist.Taps of the usual type, which are also used in the case of air pressure brakes on the brake cylinders and lines are attached, and which are used to achieve a safe shut-off of the compressed air, often open automatically, which causes all kinds of malfunctions. The one shown Hahn is supposed to remedy this inconvenience, with every external obstruction which Is exposed to dirt and ice, as well as to external weather influences, is avoided. Das Hahnküken a, Fig. 1, hat nach der Verschlufsschraube zu eine Verlängerung, welche einestheils als Führung für eine darauf gleitende Hülse b, anderentheils als Mitnehmer für die erwähnte Hülse b dient. Diese Hülse b hat zwei radial stehende Ansätzen, Fig. 5, welche bei geschlossenem Hahn in zwei gleichfalls radial angewendeten Vertiefungen y des Hahngehäuses c, Fig. 3, in der durch Fig. 4 dargestellten Weise eingreifen. In dieser Stellung drückt die Feder \ die Hülse b gegen den Ansatz η des verlängerten Hahnkükens und dichtet denselben ab; gleichzeitig drückt auch die Feder \ die Hülse b mit ihren Ansätzen χ in die Vertiefungen y und sperrt den Hahn. Soll nun der Hahn nach rechts oder links geöffnet werden, so wird das Küken durch den Hebel gedreht und nimmt mittelst des Mitnehmers e die Hülse b mit. Die Ansätze χ der Hülse b gleiten an den schiefen Ebenen der Vertiefung j/" empor, verschieben die Hülse b auf dem Mitnehmer e und entlasten dadurch das Küken von dem Federdruck. Ist die Drehung so weit erfolgt, dafs die Ansätze χ auf der ebenen Fläche f des Hahngehäuses angelangt sind, so wird der Hahn in der geöffneten Stellung festgehalten.The cock plug a, Fig. 1, has an extension after the screw plug, which on the one hand serves as a guide for a sleeve b sliding on it, on the other hand as a driver for the aforementioned sleeve b . This sleeve b has two radially standing projections, FIG. 5, which, when the cock is closed, engage in two likewise radially applied depressions y of the cock housing c, FIG. 3, in the manner shown by FIG. In this position, the spring \ presses the sleeve b against the extension η of the elongated cock plug and seals it off; At the same time, the spring \ presses the sleeve b with its lugs χ into the indentations y and blocks the valve. If the cock is now to be opened to the right or left, the chick is turned by the lever and takes the sleeve b with it by means of the driver e. The lugs χ of the sleeve b slide up the inclined planes of the recess j / ″, move the sleeve b on the driver e and thereby relieve the plug from the spring pressure. Once the rotation has taken place so far that the lugs χ on the flat surface f of the tap housing have arrived, the tap is held in the open position. Durch Zurückdrehen des Hebels nach der Mittelstellung werden die Ansätze χ den Vertiefungen y wieder näher gebracht, und sobald die Ansätze die schiefe Ebene von y erreicht haben, schliefst sich der Hahn wieder von selbst.By turning the lever back to the middle position, the attachments χ are brought closer to the indentations y , and as soon as the attachments have reached the inclined plane of y , the tap closes again by itself. Patenτ-Anspruch:Patenτ claim: Ein Hahn, welcher sich mittelst einer durch das Küken mitgenommenen, mit Ansätzen χ versehenen Hülse b, die in entsprechende Vertiefungen y des Hahngehäuses eingreift, selbstständig geschlossen hält, und welcher nur durch äufsere Hebelbewegung geöffnet werden kann, wobei das Hahnküken vom Federdruck entlastet wird.A cock, which is automatically closed by means of a sleeve b which is carried along by the plug and provided with lugs χ , which engages in corresponding indentations y of the cock housing, and which can only be opened by an external lever movement, whereby the cock plug is relieved of spring pressure.
