### Gas-hydraulic damper

###### REGENERATIVE CENTER SECTION

##### Gas-hydraulic damper

##### Extrusion Bolts – Cold Drawn Bars (CDB)

##### The gas-hydraulic damper with friction springs combines the functionality of a single acting damper with a friction spring. This design not only dissipates energy during compression but also provides additional stroke and efficient energy absorption under tensile loads.

##### Product features:

- Integrated system combining energy absorption via a gas-hydraulic capsule and a set of friction springs
- Energy absorption during both compression (gas-hydraulic capsule) and tension (friction spring set)
- Protection against the snatch effect

**Customer benefits**

### Single acting damper

###### REGENERATIVE CENTER SECTION

##### Single acting damper

##### Single acting damper

##### The single-acting damper absorbs energy in compression, effectively reducing impact forces during coupling and collisions. Its regenerative function optimizes energy dissipation, minimizing deceleration for enhanced safety. The adjustable design enables precise force distribution control to meet specific vehicle configuration and operational needs.

##### Product features:

**Customer benefits**

- Regenerative energy absorption during daily coupling operations.
- The buffer can be optimized so that the deceleration is always reduced to a minimum.
- Optimized weight
- Integrated anti-rotation function

### Double acting damper

##### Double acting damper

##### The double-acting damper absorbs energy in both compression and extension, providing superior protection in dynamic applications. Its regenerative function ensures efficient energy dissipation while keeping deceleration as low as possible. The damper’s adjustable settings enhance performance and adaptability across various operating conditions.

##### Product features:

- Regenerative energy absorption during daily coupling operations.
- The damper can be optimized so that the deceleration is always reduced to a minimum
- Protection against the snatch effect
