Engine Vibration Dampers

Geislinger Damper

It is most commonly mounted at the free-end of the crankshaft or camshaft and consists of a primary and a secondary section. Between these, groups of leaf spring packs are arranged.

These spring packs together with intermediate pieces and the secondary section form chambers which are filled with pressurized engine oil.

The elasticity is determined by the shape and number of springs. In this way the torsional system is detuned and the most critical resonance eliminated.

If the exterior section vibrates in relation to the inner one, the leaf springs bend and the pressurized engine oil is pumped from one chamber into another. This reduces the relative motion of the two parts and thus dampens the residual torsional vibration.


Geislinger Vdamp®

The Geislinger Vdamp® and Vdamp®XT protect engine camshafts and crankshafts from damage through torsional vibration. 

It also helps avoid barred speed ranges. It consists of two main elements: the housing and an inertia ring. These two parts are elastically connected with silicone oil and guided by high-tech polymer elements. In the case of vibration, the housing accelerates relative to the inertia ring – shearing the silicone oil and by this creating damping. The vibration energy is transformed into heat and dissipated by the damper surface to the ambient air.

Targeting OEM usage, retrofit solutions are also possible to improve your propulsion system performance. In-house oil sampling at Geislinger ensures fast response and highly accurate lifetime forecasts. The sophisticated calculation methods and unique lifetime extension system makes the Geislinger Vdamp® a proud member of the “Built to last“ family.
