Description
Es sind Steuerorgane für Preßluft, Dampf und Gas in verschiedenen Ausführungen bekannt. Meistens haben dieselben metallische Dichtungsflächen, welche den Nachteil haben, bei kurzzeitigem Gebrauch zu verschleißen und schwer gängig zu werden: Der Verschleiß der Dichtungsflächen führt dabei oft zu Riefenbildungen und Undichtigkeiten, welche sich im Betrieb unliebsam: und störend bemerkbar machen. Außerdem ist der Verlust durch Undichtigkeiten ein kostspieliges Übel.There are different controls for compressed air, steam and gas Executions known. Most of the time the same metallic sealing surfaces have which have the disadvantage of wearing out with short-term use and being difficult to move to become: The wear of the sealing surfaces often leads to the formation of grooves and leaks, which are unpleasant and annoying during operation. In addition, leakage is a costly evil.
Um alle erwähnten Nachteile zu vermeiden, schlägt die Erfindung einen Steuerschieber vor, welcher mittels eines Stufenkolbens, daran angebrachten -Dichtungsringen und auf dem Kolben verschiebbar und federnd angeordneten Dichtungsklappen eine absolute Dichtigkeit gewährleistet. Da hierbei keine unter einseitigem Druck stehende Flächenreibung entsteht, ist der vorgeschlagene Steuerschieber keiner großen Abnutzung unterworfen und immer leicht gängig. Die Umsteuerung des Steuerschiebers erfolgt durch einen Handhebel, durch dessen Betätigung der Kolben im Gehäuse verschoben und Ein- und Ausströmung gewechselt wird.In order to avoid all of the disadvantages mentioned, the invention proposes one Control slide before, which by means of a stepped piston, sealing rings attached to it and sealing flaps, which are slidably and resiliently arranged on the piston, an absolute Guaranteed tightness. Since there is no surface friction under one-sided pressure arises, the proposed spool is not subject to great wear and always easy to use. The control spool is reversed by a Hand lever, which moves the piston in the housing and inputs and Outflow is changed.
In der Zeichnung ist ein Steuerschieber in einem Ausführungsbeispiel als Vierwegeschieber im Schnitt dargestellt. Das einströmende Medium gelangt durch die Hauptanschlußöffnung a und den Kanal b in den Schieberraum. c, strömt durch die Löcher d in den hohl gebohrten Kolbenschieber e und von hier durch den Anschluß f, während das verbrauchte Medium durch den Anschluß g, den Überströmkanal h und den Anschluß i ins Freie gelangt. Eine vollkommene Abdichtung der Druckseite erfolgt durch die auf dem Kolbenschieber e angebrachten elastischen Dichtungen k und die ebenfalls mit einer elastischen Dichtung versehene, federnd angeordnete Dichtungsklappe 1. In Mittelstellung wird der Kanal b durch den Kolbenschieber e geschlossen, während die beiden Dichtungsklappen 1 den Überströmkanal h beiderseitig verschließen. . Nach erfolgter Verschiebung des Kolbenschiebers e in die andere Endstellung erfolgt eine Umsteuerung der Wege, so daß das Medium durch den Anschluß g geleitet wird und das verbrauchte Medium durch den Anschluß f, den Überströmkanal h und den Anschluß i ins Freie gelangt.In the drawing, a control slide is shown in one embodiment as a four-way slide in section. The inflowing medium passes through the main connection opening a and the channel b into the valve chamber. c, flows through the holes d into the hollow piston valve e and from here through the connection f, while the used medium passes through the connection g, the overflow channel h and the connection i into the open. The pressure side is completely sealed off by the elastic seals k attached to the piston valve e and the resilient sealing flap 1, which is also provided with an elastic seal close on both sides. . After the piston slide e has been moved into the other end position, the paths are reversed so that the medium is passed through connection g and the used medium passes through connection f, overflow channel h and connection i into the open.
