Abstract

Bei einem Rammbohrgerät zum Herstellen von Erdbohrungen mit einem in einem Gehäuse hin- und herbewegten Schlagkolben (8) ist auf einem in die Schlagkolbenkammer (7) hineinragenden Steuerrohr (4) eine Steuerhülse (10) geführt, deren axiale Lage die Bewegungsrichtung des Gerätes bestimmt. Um eine Bewegungsumkehr zu ermöglichen, ist eine Umsteuerkammer (14) mit einer im Steuerrohr (4) verlaufenden Steuerluftleitung (18,19) und eine Vorlaufkammer (15) über eine Bohrung (20) mit dem Innern des die Betriebsluft in die Schlagkolbenkammer (7) zuführenden Steuerrohrs (4) verbunden. Demgemäß wird die Steuerhülse (10) in der einen Richtung mit Hilfe der Steuerluft und in der anderen Richtung mit Hilfe der Betriebsluft bewegt.
