Die Erfindung bezieht sich auf ein Steuerventil für Luftdruckbremsen mit Leitungsauslaß, welches durch einen im Steuerkolben geführten, durch Leitungsdruck beeinflußten Kolben gesteuert wird. Gegenstand der Erfindung ist eine Abänderung der Steuerung des Auslaßventils, welche darin besteht, daß die Steuerkammer des Auslaßsteuerkolbens durch einen winkelförmigen Kanal in der ,The invention relates to a control valve for air pressure brakes with a line outlet, which through a control piston guided piston influenced by line pressure is controlled. Subject of the invention is a modification of the control of the exhaust valve, which consists in that the control chamber of the exhaust control piston through an angular channel in the,

The figure shows a vertical section through the control valve.

Der Kolben 2 ist auf der einen Seite beständig dem Druck in der Zugleitung und auf der anderen Seite dem Druck der in der Kammer 21 eingeschlossenen Luft ausgesetzt, welche in der dargestellten Lösestellung des Steuerventils durch den Kanal 33 in der Stange 20 des Kolbens 2 mit der Zugleitung in Verbindung steht.line, which can pass air into the channel 11 when it opens, which the Outlet opening 15 exposing piston 14 reversed. The piston 2 is on one side resistant to the pressure in the train line and on the other hand to the pressure in the chamber 21 trapped air exposed, which in the illustrated release position of the Control valve through channel 33 in rod 20 of piston 2 with the train line communicates.
Kanal 33 ist mit der seitlichen öffnung 34 versehen, welche in der .Lösestellung des Kolbens 1 freigelegt wird, während sie in -.Channel 33 is provided with the lateral opening 34, which in the .Löseststellung des Piston 1 is exposed while in -.
allen übrigen Stellungen des Kolbens 1 in die Kolbenstangenführung eintritt und durch letztere überdeckt wird, so daß jede weitere Verbindung zwischen der Zugleitung und der Kammer 21 abgeschnitten wird. Die in dieser befindliche Luft bleibt also in der Kammer eingeschlossen und hält den Kolben 2 in seiner Stellung, so daß in der Notbremsstellung des Kolbens 1 Ventil 13 geöffnet erhalten wird und Leitungsluft in den Kanal 11 eintreten kann. Diese steuert den Kolben 14 um, welcher die Auslaßöffnung 15 freilegt und das Ventil 27 öffnet, so daß auch eine Verbindung zwischen dem Hilfsluftbehälter 23 und dem Bremszylinder durch Kanal 30 und Ventil 28 eröffnet wird. Sobald der auf das Ventil 27 wirkende Hilfsbehälterdruck den auf den Kolben 14 wirkenden Leitungsdruck überwindet, wird der Leitungsauslaß 15 und die Verbindung zwischen Hilfsbehälter und Bremszylinder wieder abgeschlossen. Das Ventil 13 wird schließlich dadurch geschlossen, daß der Druck in der Kammer 21 sich herabmindert, indem Luft durch den undichten Stülp des Kolbens 2 hindurchtritt.all other positions of the piston 1 enters the piston rod guide and through the latter is covered so that any further connection between the train line and the chamber 21 is cut off. The one in this Any air that is present remains trapped in the chamber and keeps the piston 2 in its position, so that in the emergency braking position of the piston 1 valve 13 get open and duct air can enter duct 11. This controls the piston 14 around, which exposes the outlet opening 15 and opens the valve 27, so that also a Connection between the auxiliary air reservoir 23 and the brake cylinder through channel 30 and Valve 28 is opened. As soon as the auxiliary tank pressure acting on the valve 27 opens the overcomes the piston 14 acting line pressure, the line outlet 15 and the connection between the auxiliary container and the brake cylinder is completed again. The valve 13 is finally closed by the fact that the pressure in the chamber 21 is reduced, in that air passes through the leaky invert of the piston 2.
Bei Betriebsbremsungen, die durch geringere Druckminderungen in der Leitung bewirkt werden, verschiebt sich der Steuerkolben 1 so langsam nach links, daß noch etwas Luft aus der Kammer 21 durch die Öffnung 34 entweichen kann. Die in der Kammer eingeschlossene Druckluft ist daher nicht im Stande, den Widerstand der Feder zu über-In the event of service brakes caused by lower pressure reductions in the line the control piston 1 moves so slowly to the left that there is still some air can escape from the chamber 21 through the opening 34.
