Description

mit Ventilverschlußkörpern 25, z.B. Gummischeiben, versehen. In die Schaltventilkammer 10 führt ein Einlaßkanal 17 für ein Druckmittel. Außerdem münden in der Schaltventilkammer iO gegenüber den Ventilverschlußkörpern 25 A-uslaßkanäle 15 und 16, welche je nach der Stellung des Betätigungshebels 8 alternativ geöffnet bzw. geschlossen sind. In der in Abb. 1 eingezeichneten Ruhestellung des Betätigungshebels 8 steht der Einlaßkanal 17 mit dem Auslaßk&nal 15 in Verbindung, während der Auslaßkanal 16 abgeschlossen ist. Wenn der Druck in der Steuerkammer 12 durch einen entsprechenden Impuls in dem Kanal 24 so hoch ansteigt, daß die Gegenkraft der Feder 14 überwunden wird, so drehtwith valve closure bodies 25, e.g. rubber washers, Mistake. An inlet channel 17 for a pressure medium leads into the switching valve chamber 10. aside from that open into the switching valve chamber OK opposite the valve closure bodies 25 outlet channels 15 and 16, which are alternatively open or closed depending on the position of the operating lever 8. In the in Fig. 1 shown rest position of the actuating lever 8 is the inlet channel 17 with the outlet channel 15 in connection, while the outlet channel 16 is closed. When the pressure in the Control chamber 12 rises so high by a corresponding pulse in channel 24 that the counterforce the spring 14 is overcome, so rotates
