HYDRAULISCHE BREMSANLAGE DES ELEKTRISCH GESTEUERTEN TYPS FÜR FAHRZEUGE

摘要

An hydraulic braking system of the brake-by-wire type has an hydraulic pressure source comprising an hydraulic accumulator adapted to be charged by a pump. An accumulator isolating valve is so positioned and biased to correspond to the direction of flow from the accumulator to a solenoid-operated proportional valve. The valve is biased into a closed position in opposition to the flow from the pump to the accumulator.
