Abstract

A device for controlling weight on bit of a drilling assembly for drilling a borehole in an earth formation, is provided. The device comprises a fluid passage (24, 26) for the drilling fluid flowing through the drilling assembly, and control means (14, 16) for controlling the flow resistance of drilling fluid in said passage in a manner that said flow resistance increases when the fluid pressure in the passage decreases and that said flow resistance decreases when the fluid pressure in the passage increases.
