 Widerstände beseitigt. 



   Hiezu kommt ausserdem noch, dass durch den Wegfall dieses hohen Druckes auch ein Einfressen und   Festbacken   der Dichtungsflächen nicht leicht möglich ist. 



     Der grösstmögliche Druck   auf den Keil eines solchen Schiebers tritt im Augenblicke des () ffnens auf und wird durch den beim Schluss erzeugten Keildruck als Dichtungsdruck hervorgerufen. 



   Die Vorteile dieser Konstruktion sind also geringe Anzugs-und Hubkräfte, daher leichte Wind werke ; höhere Betriebssicherheit und günstigere   Übersetzung   ; kleinere Hubzeit ; Wegfall vorgeschalteter Drosselklappen samt Sickerwasserschieber, somit Freigabe des vollen Lichtprofiles.

 EMI2.1
 Resistance eliminated.



   In addition, the absence of this high pressure means that it is not easy for the sealing surfaces to seize and stick.



     The greatest possible pressure on the wedge of such a slide occurs at the moment of () opening and is caused by the wedge pressure generated at the end as sealing pressure.



   The advantages of this construction are low pulling and lifting forces, therefore light wind works; higher operational reliability and cheaper translation; shorter lifting time; Elimination of upstream throttle valves including seepage water slide, thus enabling the full light profile.

PATENT-ANSPRUCH : Entlasteter Schieber für flüssige oder gasförmige Druckmittel mit einer der Druckfläche gleich grossen Entlastungsnäche auf der der Druckfläche gegenüberliegenden Keilseite, dadurch EMI2.2 fläche (b) zweckmässig halbmondförmig gestaltet und die Rückseite der Entlastungsfläche mit der Niederdj'uckseite durch Kanäle (g) verbunden ist, die sowohl zum Druckausgleich des Mittels von niederem Drucke als auch als Abflussorgane für gegebenenfalls sich bildendes Sickerwasser EMI2.3 PATENT CLAIM: Relieved slide for liquid or gaseous pressure medium with a relief surface equal to the pressure surface on the wedge side opposite the pressure surface, thereby EMI2.2 surface (b) is appropriately designed crescent-shaped and the back of the relief surface is connected to the lower pressure side by channels (g), which are used both for pressure compensation of the means of low pressures and as drainage organs for any seepage water that may form EMI2.3
