KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen doppelt wirkenden, elektrisch gesteuerten Preßluftantrieb für Eisenbahnsignale u. dgl., bei dem eine begonnene Bewegung jederzeit in die entgegengesetzte durch Preßluft umgewandelt werden kann. Das Wesen der Erfindung besteht darin, daß beim Unterbrechen des Steuerstromes das Signal durch einen Schieber zwangsweise auf Halt bewegt wird. In der ίο Haltstellung des Signales werden durch den Schieber die Zu- und Auspuffleitungen abgesperrt. The invention relates to a double-acting, electrically controlled compressed air drive for railway signals and the like, in which a movement that has begun always changes into the opposite can be converted by compressed air. The essence of the invention is that when the control current is interrupted the signal is forced to stop by a slider. In the ίο stop position of the signal, the Slide shut off the supply and exhaust lines.
Die Einrichtung besteht aus einem Stellzylinder ι und einer Schiebersteuerung 3, 7, 6, die beim Fahrtstellen durch den bekannten Ventilmagneten 8, 9, io, beim Haltstellen des Signales kraftschlüssig durch die Feder 7 bewegt wird.The device consists of an adjusting cylinder and a slide control 3, 7, 6, the when driving by the known valve magnet 8, 9, io, when stopping the Signal is positively moved by the spring 7.

Fig. 3 den Preßluftantrieb in der Fahrtlage, Fig. 4 die Lage des Schiebers, wenn der Steuerstrom unterbrochen ist,Fig. 3 shows the compressed air drive in the driving position, Fig. 4 shows the position of the slide when the Control current is interrupted,
Fig. 5 die Schiebersteuerung kurz vor der Hubvollendung des Kolbens.5 shows the slide control shortly before the piston has completed its stroke.
Die Wirkungsweise des Antriebes ist folgende:The operation of the drive is as follows:
Wird der Ventilmagnet 8, 9 erregt, so strömt die Preßluft aus der Leitung 11 unter den Steuerkolben 10 und bewegt ihn so weit, bis der Kanal 14 mit der Einlaßöffnung 17 verbunden ist (Fig. 2). In dieser Lage gelangt die Preßluft über den Stellkolben 2 und treibt das Signal in die Fahrtstellung (Fig. 3).If the valve magnet 8, 9 is excited, the compressed air flows under from the line 11 the control piston 10 and moves it until the channel 14 with the inlet port 17 is connected (Fig. 2). In this position, the compressed air reaches the actuating piston 2 and drives the signal in the driving position (Fig. 3).
Wird während des Einstellens oder in der Fahrtlage des Signales der Strom unterbrochen, so drückt die gespannte Feder 7 den Schieber 3 so weit zurück, bis der Federbolzen 6 an· die Kolbenstange 4 anschlägt (Fig. 4).If the current is interrupted while the signal is being set or in the driving position, so the tensioned spring 7 pushes the slide 3 back until the spring bolt 6 hits the Piston rod 4 strikes (Fig. 4).
Hierdurch ist der Schieber 3 für die Rückstellung des Signales umgesteuert, und die Preßluft strömt nun durch die Kanäle 18, 15, unter den Stellkolben 2, der das Signal in die Ruhelage bringt.As a result, the slide 3 is reversed for resetting the signal, and the Compressed air now flows through the channels 18, 15, under the actuating piston 2, which sends the signal brings it to rest.
Am Schlüsse der Rückwärtsbewegung des Stellkolbens tritt der an der Kolbenstange 4 angebrachte Einschnitt 5 vor den Federbolzen 6 (Fig. 5), der der entlasteten Feder folgend den Steuerschieber 3 in die Ruhelage zurückdrückt.At the end of the backward movement of the actuating piston, the piston rod 4 occurs attached incision 5 in front of the spring bolt 6 (Fig. 5), which follows the relieved spring Pushes control slide 3 back into the rest position.
