Abstract

Die Erfindung betrifft eine Erdbohrvorrichtung mit einem Grundkörper und einem hierzu in längsaxialer Richtung beweglich gelagerten Bohrkopf, wobei zwischen dem Bohrkopf und dem Grundkörper ein durch die bewegliche Lagerung in seiner Größe veränderlicher Freiraum ausgebildet ist, und mit einem Dichtelement zur Abdichtung des Freiraums gegenüber der Umgebung, wobei das Dichtelement als Ventilelement ausgebildet ist, das bei einem innerhalb des Freiraums herrschenden Überdruck öffnet, um einen Druckausgleich herzustellen, und das bei einem innerhalb des Freiraums herrschenden Unterdruck verschlossen ist, um einen Druckausgleich zu verhindern.
