Zusatz zum Patent 258390.Addition to patent 258390.

Patentiert im Deutschen Reiche vom 28. Oktober 1911 ab. Längste Dauer: 8. September 1926.Patented in the German Empire on October 28, 1911. Longest duration: September 8, 1926.

Bei der Einrichtung nach dem Hauptpatent geschieht zwecks Einleitung einer Betriebsbremsung die Entlüftung des vorderen Zugteiles vom Führerstande aus, während bei Notbremsungen der Lokomotivführer die Entlüftung des vorderen und ein am Zugschluß befindlicher Zugbegleiter die Entlüftung des hinteren Zugteiles vorzunehmen hat.In the device according to the main patent, the front pull part is vented to initiate a service brake from the driver's cab, while in the event of emergency braking the engine driver does the ventilation of the front and a train attendant located at the end of the train the ventilation of the rear Train part has to make.

Gemäß der vorliegenden Zusatzerfindung ist das im Zuge angeordnete Rückschlagventil mit einem Auslaßventil vereinigt, das sich bei erheblichen, im vorderen Zugteil vorgenommenen Druckminderungen öffnet und den hinteren Zugteil selbsttätig entlüftet, wodurch das Vorhandensein einer zweiten, den Auslaß am Zugschluß bedienenden Person überflüssig wird.According to the present additional invention, the check valve arranged in the train is combined with an exhaust valve, which is made in the case of considerable, in the front pull part Pressure reductions opens and the rear part of the pull is automatically vented, thus reducing the presence a second person operating the outlet at the end of the train becomes superfluous.

In der Zeichnung ist das mit dem Rückschlagventil vereinigte Auslaßventil im Längsschnitt dargestellt.In the drawing, the outlet valve combined with the check valve is in longitudinal section shown.

Das den Gegenstand des Hauptpatentes bildende Rückschlagventil wird durch ein Auslaßventil ergänzt, das einen Differentialkolben enthält. Die Kolbenkammer A, die durch den größeren Kolben F1 abgeschlossen wird, steht mit dem vorderen Zugteil in Verbindung, während die Kolbenkammer B des kleineren Kolbens F2 sich gegen den hinteren Zugteil öffnet.The check valve forming the subject of the main patent is supplemented by an outlet valve which contains a differential piston. The piston chamber A, which is closed by the larger piston F 1 , is in communication with the front pull part, while the piston chamber B of the smaller piston F 2 opens towards the rear pull part.

Beide Kolben werden durch eine hohle Stange von bestimmtem Durchmesser verbunden, in der eine schwache Feder r gelagert ist, die den Differentialkolben in der gezeichneten Stellung zu erhalten sucht, in der der Kolben F2, die Auslaßöffnung des hinteren Zugteiles verschließt. Both pistons are connected by a hollow rod of a certain diameter in which a weak spring r is mounted, which seeks to maintain the differential piston in the position shown, in which the piston F 2 closes the outlet opening of the rear traction part.

Wird eine Betriebsbremsung vorgenommen, bei der nur eine mäßige Druckminderung in dem vorderen Teil der Zugleitung eintritt, so hält der auf die vordere Seite des größeren Kolbens wirkende, durch die Feder r unterstützte Hauptleitungsdruck, auch nachdem er um einen gewissen Betrag gemindert ist, entgegen dem auf die kleinere Fläche des großen Kolbens wirkenden, ungeminderten Leitungsdruck des hinteren Zugteiles das Ventil F1, F2 in der gezeichneten Stellung, in der die Aus-Strömungsöffnung des hinteren Zugteiles geschlossen bleibt. Erst wenn bei Einleitung einer Notbremsung eine stärkere Druckminderung des vorderen Zugteiles vorgenommen wird, überwiegt der in der Kammer B herrsehende Druck des hinteren Zugteiles den geminderten Druck in der Kammer A, das Ventil steuert entgegen dem Druck der Feder r um, und der hintere Zugteil wird entlüftet.If service braking is carried out in which only a moderate pressure reduction occurs in the front part of the train line, the main line pressure acting on the front side of the larger piston and supported by the spring r holds against this, even after it has been reduced by a certain amount the valve F 1 , F 2 in the position shown, in which the outflow opening of the rear pull part remains closed, acts on the smaller area of the large piston, undiminished line pressure of the rear pull part. Only when a greater pressure reduction in the front pulling part is made when an emergency braking is initiated does the pressure of the rear pulling part in chamber B outweigh the reduced pressure in chamber A, the valve reverses against the pressure of spring r , and the rear pulling part becomes vented.
