Anordnung mit einer Ventileinrichtung

摘要

The valve system supplies pressure from a source to an operator (12), e.g. a pedal, which is also subjected to a spring. The spring force is adjustable, and is dimensioned so that the arrangement has a preset actuating force requirement. The spring (30) is positioned to engage on the pedal outside the pressure force. The pedal also operates a further device, e.g. an electrical braking power indicator (26).
