There are mainly three ways to generate torque with a damper.
- Pressure : moves like a syringe
- Sliding Resistance : friction movement
- Shear Resistance : moves like scissors
They are used for the following types of dampers.
- Pressure → Finite angle damper
- Sliding Resistance → Friction damper
- Shear Resistance → Infinite angle damper
