Abstract

The piston (13) inside a trigger cylinder (10) is activated when the clutch pedal is pushed, moving the pressurized fluid towards the outlet (16). Vibrations transmitted into the fluid are guided to a narrow segment at the dampening element (19), through a radial bore with a narrower diameter, through the central bore (12) and finally to an opening in a cap-shaped membrane. The membrane is extended laterally resulting in a second step of vibration absorbing.
