Abstract

A rock drill includes a liquid-flushed, pot-shaped drilling head axially movable, within predetermined limits, relative to the drill rod which forms a piston that defines, together with an inner surface of the drilling head, a variable volume filling chamber, and at least one hydrodynamical narrow opening for filling the filling chamber with fluid,
