Master cylinder for electro hydraulic braking systems, has hydraulic-damping unit with shut off unit placed between longitudinal end of supply duct and one of exhaust duct to reduce flow rate of brake fluid

摘要

The master cylinder has hydraulic-damping unit (48) for damping return of a piston head to bear against a thrust ring. The hydraulic-damping unit has a sealed shut off unit (41) placed between a longitudinal end of a supply duct (24) and one of exhaust ducts (50, 54, 58, 60, 72) through which brake fluid flow from the supply chamber (14) to the supply duct (24).
