Title:
ハイドロリック式の車両用ブレーキ装置
Document Type and Number:
Japanese Patent JP4073493
Kind Code:
B2
Abstract:
A hydraulic brake system for a vehicle for braking the vehicle by brake pedal actuation and/or automatic braking. A pump is provided which has a suction connection that communicates with a supply container for a pressure fluid and a pressure connection for aspirating pressure fluid from the supply container and pumping the fluid to a connection of a master cylinder. A brake circuit of the vehicle brake system is connected with vehicle wheels associated with wheel brake cylinders and with valve assemblies for brake pressure modulation and is connected to the connection of the master cylinder. A valve pressure is also provided between a pressure chamber that communicates with the connection of the master cylinder and the supply container for pressure fluid. The pressure valve is actuatable by pump pressure in automatic braking, which at low pump pressure throttles the fluid flow through the pressure chamber of the master cylinder to the supply container and which limits this pressure at pump pressure that is elevated in comparison.
