Abstract

Es wird ein Bohrhammer vorgeschlagen, der ein in einem Maschinengehäuse (11) untergebrachtes, axial verschiebbares Führungsrohr (12) aufweist, das mit Entlüftungsöffnungen (36) zur Leerlaufsteuerung versehen ist. Die Entlüftungsöffnungen (36) sind mittels eines Schließgliedes (37) abdeckbar, das durch eine Mehrfunktionshülse (25) gebildet wird. Die Mehrfunktionhülse (25) trägt weiterhin eine Arretierverzahnung (67) zur drehfesten Festlegung des Führungsrohrs (12). Darüber hinaus bildet die Mehrfunktionshülse (25) eine Lagerstelle (23) zur Lagerung des Führungsrohrs (12).
