AGENCEMENT DE COMMANDE DE FREINAGE COMPORTANT UN SERVOMOTEUR EQUIPE D'UN REGULATEUR DE PRESSION DEPORTE ET D'UNE VALVE DE REEQUILIBRAGE RAPIDE

摘要

The arrangement has a pneumatic servomotor comprising a control piston coupled with a brake pedal, where the piston is mounted to slide between rear rest and front positions. A hydraulic or pneumatic pressure regulator is arranged outside a rigid envelope and includes a balancing valve allowing a vacuum chamber (24) to communicate with a work chamber (26) through an outer pneumatic circuit. The servomotor includes a rapid rebalancing valve (120) arranged inside the envelope and allows the vacuum chamber to directly communicate with the work chamber without passing through the circuit.
