Abstract

Rammbohrgerät mit einem in einem Gehäuse (1) axial beweg­ lichen, in seiner Bewegung durch ein mit einem Druckluft­ schlauch (6) verbundenes, in einem im Gehäuse (1) angeordne­ ten elastischen Zwischenstück (4) gelagertes Steuerrohr (3) gesteuerten Schlagkolben (2), bei dem das elastische Zwi­ schenstück (4) am Steuerrohr (3) und/oder im Gehäuse (1) angeordnet ist, wird die Montage des Zwischenstücks (4) vereinfacht. Außerdem treten weniger Beschädigungen am Ge­ häuse (1), Steuerrohr (3) und Druckluftschlauch (6) auf, und auch das Steuerrohr (3) läßt sich leichter montieren und demontieren.
