A device for providing directional control to a borehole being drilled. The device is used with a drilling system including a drill string, a downhole motor and a bit rotated by the downhole motor. The device exerts a deflecting force perpendicular to the axis of the drill string when a lower than normal thrust is imposed on the drill string, and exerts an opposite perpendicular force when a higher than normal thrust is imposed on the drill string. When normal thrust is being used, the device does not cause deflection in either direction.
