Abstract

Die Erfindung bezieht sich auf ein fluidbetriebenes Schlagwerk (1) mit einem Schlagkolben (3), der unter Einwirkung einer Steuerung (5) wechselweise einen Arbeitshub und einen Rückhub ausführt.
Zur Vermeidung von Leerschlägen wird eine Ausgestaltung des Schlagwerks (1) vorgeschlagen, durch welche der Schlagkolben (3) stillgesetzt wird, falls er die sich im Normalbetrieb (Langhub- und/oder Kurzhubbetrieb) ergebende Ausfahrstellung in Arbeitshubrichtung (Pfeil 3e) um ein vorgegebenes Wegstück bis zur Einnahme einer Leerschlagstellung überfahren hat. Zu diesem Zweck weist der Innenraum (2d) des den Schlagkolben (3) aufnehmenden Arbeitszylinders (2) zusätzlich eine Leerschlag-Einmündung (20a) auf, die unter Zwischenschaltung eines zwischen einer Außerbetriebstellung und einer Wirkstellung umschaltbaren Sicherungselements (21) mit der Druckleitung (8) des Schlagwerks (1) in Verbindung steht.
