Abstract

Die erfindungsgemässe Bohrvorrichtung 1 weist eine Spülvorrichtung zum Spülen einer Bohrung 5 mit einem Spülfluid 7 auf. Eine hydraulisch angetriebene Vortriebseinrichtung 21 ist vorgesehen einen Bohrer 2 in der Bohrung 5 vorzutreiben. Ein Durchflussbegrenzer 30 ist in Hydraulikleitungen 25 der Vortriebseinrichtung 21 angeordnet, um die Vortriebsgeschwindigkeit einzustellen. Der Durchflussbegrenzer 30 weist ein durch Druck betätigbaren Stellelement 38 zum Einstellen einer Durchflussbegrenzung auf. Eine pneumatische, hydraulische und/oder mechanische Kopplung 39 überträgt den Druck des Fluids 7 auf das Stellelement 38.

The drilling device 1 according to the invention has a flushing device for flushing a bore 5 with a flushing fluid 7. A hydraulically driven propulsion device 21 is provided to propel a drill 2 in the bore 5. A flow restrictor 30 is disposed in hydraulic lines 25 of the propulsion device 21 to adjust the propulsion speed. The flow restrictor 30 includes a pressure operable actuator 38 for adjusting a flow restriction. A pneumatic, hydraulic and / or mechanical coupling 39 transmits the pressure of the fluid 7 to the actuator 38.
