Abstract
Mit der Erfindung wird eine Ausgestaltung des Schlagwerks (1) vorgeschlagen, die bei Überschreiten einer Schlagkolben-Grenzstellung in Richtung des Arbeitshubs (Pfeil 3e) die Umschaltung des Steuerventils (5) in die Rückhubstellung auslöst. Während des unmittelbar nachfolgenden Rückhubs wird durch Druckbeaufschlagung einer Kurzhubleitung (18) das Steuerventil (5) vorzeitig in die Arbeitshubstellung verschoben, so daß der Schlagkolben (3) lediglich einen Kurzhub ausführt.
