Controllable braking system has coupled sensing, control and braking arrangement; braking arrangement has at least two mutually relatively movable parts; relative motion is limited by fluid

摘要

The system has a sensing arrangement (50), a control arrangement (60) and a braking arrangement (70) coupled together. Sensor signals are converted into a braking effect on the rotary flap (20) motion by the control arrangement using the braking arrangement. The braking arrangement has at least two mutually relatively movable parts and the relative motion is limited by a fluid.
