English: The Geislinger Damper utilizes steel leaf springs and engine oil. The steel springs are tuned to optimize the natural frequency of a system and engine oil is used to reduce torsional vibrations. Geislinger uses specially developed software to select the specific damper parameters which best protect the engine crank- and camshaft, as well as intermediate and propeller shafts from damage due to critical vibratory loads. The Geislinger Damper provides constant stiffness and very high damping over the damper life, independent of engine room temperature.
