"Apparatus provided between a stationary and a mobile member member, apparatus for a propulsion system in the downward hole drill a drill hole with a drill, controller of impulse,Method for controlling a condition of excessive thrust in an installation downhole, and tool of well. An absorber is interposed between a drive device of thrust and an anchoring device that cooperate to move axially in another state.The absorber includes a housing fixed to the thrust device of anchor and a retainer connected to the device of thrust. A member of the request is operatively associated with the retainer.During a condition of excessive thrust, the thrust device provides a thrust to the state, but the state is not substantially axially moved.In such a condition.The application device absorbs the impulse that otherwise the device of thrust would give the state when the anchoring device is no longer anchoring the device to impulThey are.
