Abstract: A spring for use in downhole tools delivers a high force over a long deflection in a relatively uniform fashion. The spring is a tubular shape that is preferably metallic and is preferably plastically deformed into an undulating walled tube either before assembly into a downhole tool or downhole after assembly to the downhole tool. Alternatively the shape can be machined. Spacer rings are used inside and outside the tube as it is compressed to obtain the desired corrugated wall pattern and to prevent localized buckling that can cause wall failure. The spring can conduct pressurized fluids and be rotationally locked to transmit torque and to facilitate milling out. Some machining internally and/or externally can assist in forming the desired corrugated wall shape.
