Hydraulic dual-circuit vehicle brake system

摘要

A hydraulic braking system has a master cylinder (12) with reservoir (13) and pipes (19,20) going to each of the brake circuits. Each circuit has pressure modulation valves (30,31) and a return delivery pump (35). Each circuit also has an automatic braking device working independently of the driver to stabilise the car against centrifugal forces. Both braking circuits are pressurised by a charging pump (46) with the reservoir on its suction side. Its pressure side connects separately to the brake circuits through non-return valves (49). There is a throttle point (23) between the main cylinder and each circuit as well as a bypass pipe (24) for this with non-return valve (25).
