Abstract

Bei einem Imlochhammer, umfassend ein im wesentlichen zylindrisches Gehäuse (10, 18), einen in einer Kolbenkammer (22) des Gehäuses (10, 18) hin- und herbewegbaren druckmittelbetätigten Schlagkolben (24), einen austauschbar angeordneten Arbeitskopf, auf den die Schlagenergie des Schlagkolbens (24) übertragbar ist, und ein mit dem Gehäuse (10, 18) drehfest verbundenes Anschlußstück (54) zur drehfesten Verbindung des Imlochhammers mit einem Bohrgestänge (108) und zum Anschluß einer Druckmittelleitung, ist der Arbeitskopf an dem dem Anschlußstück (54) fernen vorderen Ende (16) des Gehäuses (10, 18) lösbar, aber starr befestigt, wobei die Aufprallfläche (87) für den Schlagkolben (24) eine im wesentlichen achsnormale Stirnwand der Kolbenkammer (22) ist.
