摘要

A liquid-flushed pot-shaped drilling head (4) is axially moved within predetermined limits, relative to a drill rod (3). A volume variable filling chamber (8) with hydrodynamical narrow opening, is formed within the inner surface (5) of the drilling head. The narrow opening is formed as a narrow gap.
