Hydraulic damper with bottom valve and membrane
The membrane in the compensation chamber behind the bottom valve expands when loaded (pressure) or contracts (tension). The damper thus works without extension force in any installation position.
Characteristics:
● without extension force F1
● without idle stroke
● Positionally independent (installation of the piston in any position)
Application examples:
● Overrun brakes
● Commercial vehicle seats
● Belt tensioner
● Universally applicable
