VIBRATION DAMPER, hydraulic
Vibration absorbers are produced in several configurations
SINGLE TUBE VIBRATION ABSORBER
for pull and push absorption at random mounting positions.
The length is increased to keep the diameter dimension at a minimum.
TWIN TUBE VIBRATION ABSORBERS
for pull and push absorption. The preferred mounting position is vertically aligned. Compared to single tube absorbers, the length is decreased, while the diameter is enlarged.
The characteristic of damping for both types can be progressive or degressive.
