  • Device for directional drilling
    Patent number: 9644427
    Abstract: A drill string section for directional drilling includes an outer casing which encases an adjustment mechanism for adjusting drilling direction and angular deflection during drilling. The adjustment mechanism has an outer shaft that is rotatably arranged relative to the outer casing and is configured with an axial eccentric first bore having a first bore axis that is parallel to the centre axis. The adjustment mechanism further includes an inner shaft that is rotatably arranged in the first bore and is configured with an axial, eccentric second bore for passage of a drive shaft for a drill bit.
