Description

Im Abstell- und Umschalthahn nach Haupt1 patent 412911 liegt dessen Achse parallel zu der Maschinenachse bzw. quer zu der Lage der beiden zur Maschine führenden Kanäle. Diese Anordnung ist in der Praxis vielfach nicht möglichj so daß die Achse des Abstell- oder Umschaltorgans häufig quer zur Maschinenachse gelegt werden muß. Um dies bei der Bauart des Hahnes nach dem Hauptpatent zu ermöglichen, müßten die Kanäle gewunden werden, wodurch diese viel Platz beanspruchen und den glatten Durchfluß sehr behindern.In the shut-off and switchover tap according to Haupt 1 patent 412911, its axis is parallel to the machine axis or transversely to the position of the two channels leading to the machine. This arrangement is often not possible in practice, so that the axis of the parking or switching element often has to be placed transversely to the machine axis. In order to make this possible with the design of the tap according to the main patent, the channels would have to be twisted, whereby they take up a lot of space and hinder the smooth flow very much.

Durch die vorliegende Erfindung ist eijn Abstellorgan geschaffen, das in einfachster Weise die Queranordnung bei möglichst glattem Durchfluß ergibt.The present invention is a storage element created, which results in the simplest possible transverse arrangement with the smoothest possible flow.

In der Zeichnung ist beispielsweise eine solche Anordnung dargestellt; Abb. 1 zeigt ao einen Querschnitt, Abb. 2 einen Längsschnitt. A ist das Hahngehäuse, B ist das Hahnküken, C ist die Welle des Kükens, D und E sind Gehäusedeckel, F und G sind Zu- und Abführungen des Treibmittel nach der Seite der Energiequelle, und H und / sind Zu- und Abführungen des Treibmittels zur Maschine. Wie die Abb. 2 erkennen läßt, besitzt das Küken zwei schrägliegende ringförmige Wulste, die dichtend in der Gehäusebohrung gleiten und zwischen denen das Treibmittel hindurchgeführt wird. Der Rückfluß kann zwischen gleichen Wulsten erfolgen, oder wie in derIn the drawing, for example, such an arrangement is shown; Fig. 1 shows ao a cross section, Fig. 2 shows a longitudinal section. A is the cock housing, B is the cock plug, C is the shaft of the plug, D and E are housing cover, F and G are inlets and outlets of the propellant to the side of the energy source, and H and / are inlets and outlets of the propellant to the machine. As can be seen in Fig. 2, the plug has two inclined annular beads, which slide sealingly in the housing bore and between which the propellant is passed. The reflux can take place between the same beads, or as in the

Abb. i.Fig.i.

Zeichnung dargestellt ist, einseitig durch einen solchen Wulst begrenzt sein. Das Küken ist so gelagert, daß es sowohl gedreht als auch verschoben werden kann; die Darstellung zeigt eine Anordnung, bei der sich das Küken gleichzeitig mit der Drehung verschiebt. Für diesen Zweck sind in dem vorliegenden Beispiel an den Deckeln Führungsnocken vorgesehen, durch die der Zwischenraum zwischen den Wulsten stets mit der Zuführung in Verbindung bleibt. Durch Drehen wandern die Dichtungsflächen des Hahnkükens an der Seite der Maschine in der Achsrichtung der Hahnbohrung hin und her. Bei 900 Drehung sind alle Kanäle miteinander verbunden, und das Treibmittel kann frei durchfließen und zur Kraftquelle zurückgelangen, während bei l8o° Drehung Kanäle F undj / miteinander verbunden werden und die Maschine umgekehrte Drehrichtung annimmt.Drawing is shown, be limited on one side by such a bead. The chick is positioned so that it can be rotated as well as moved; the illustration shows an arrangement in which the chick shifts at the same time as it rotates. For this purpose, guide cams are provided on the covers in the present example, through which the space between the beads always remains connected to the feed. When turning, the sealing surfaces of the stopcock on the side of the machine move back and forth in the axial direction of the stopcock bore. At 90 0 rotation of all the channels are interconnected, and the blowing agent can flow freely back and return to the power source, while connected with each other at l8o ° rotation channels F and j / and assuming the machine reversed direction of rotation.
