EMI2.1
Das Steuerventil besteht in bekannter Weise aus dem Gehäuse a, dem Deckel b, dem Steuerkolben c, dem Schieber d und dem Abstufungaventil e. Bei L ist die Bremsleitung angeschlossen,
EMI2.2
Zweck einer Bremsung Luft aus der Leitung ausgelassen, so geht der Steuerkolben in seine linke Endstellung und verschiebt den Schieber a ! mit dem Abstufungsventil e in die in Fig. 2 und 3 dargestellte Lage. Hiebei \\ird die Expansionskammer 2 über die Muschel 3 mit dem zur Kolben- kammer I führenden Kanal 5 verbunden. Infolgedessen wird die vom Kolben c verdrängte Luft aus Kammer I in der Expansionskammer II aufgenommen, wird also nicht über Kanal l in die Leitung gedrückt.
In dieser Bremsstellung wird, wie in Fig. 3 dargestellt, der Hilfsluftbehälter in bekannter Weise über das Abstufungsventil e, Schieberkanal 6 und Kanal 7 mit dem Brems-

bei welchem die Expansionskammer 2 naturgemäss nur in Lösestellung mit der Aussenluft verhunden werden kann, da hiefür ja keine andere Stellung vorhanden ist. Für die Wirkungsweise des Ventils ist dies natürlich nicht von Bedeutung, da der Inhalt der Kammer 2 nur dem Volumen der Kammer I entspricht und deshalb keinen Einfluss auf den Druckabfall in der Leitung und damit auf die Grösse der Bremsstufe ausüben kann.

EMI2.1
The control valve consists in a known manner of the housing a, the cover b, the control piston c, the slide d and the graduation valve e. At L the brake line is connected,
EMI2.2
If air is let out of the line for the purpose of braking, the control piston moves to its left end position and moves the slide a! with the graduation valve e in the position shown in FIGS. Here the expansion chamber 2 is connected to the channel 5 leading to the piston chamber I via the shell 3. As a result, the air displaced by the piston c from chamber I is taken up in the expansion chamber II, so it is not forced into the line via channel l.
In this braking position, as shown in Fig. 3, the auxiliary air tank is connected in a known manner via the graduation valve e, slide channel 6 and channel 7 to the brake
EMI2.3
in which the expansion chamber 2 can naturally only be connected to the outside air in the release position, since there is no other position for this. This is of course not important for the operation of the valve, since the content of chamber 2 only corresponds to the volume of chamber I and therefore cannot influence the pressure drop in the line and thus the size of the braking stage.
