Patent ID: 7296861

Claim:
Brake system for a motor vehicle comprising a master brake cylinder in which a primary piston for generating a brake pressure in a hydraulic brake circuit can be displaced according to actuation of a brake pedal, it being possible to displace the primary piston under the effect of a hydraulic servo pressure circuit in the master brake cylinder and the hydraulic servo pressure circuit comprising a pressure source for generating the servo pressure and a pressure accumulator for maintaining a minimum servo pressure in the servo pressure circuit, wherein a fluid supply controller comprises a throttle element and in that a discharge line is constructed with a non-return valve which only allows discharge of hydraulic fluid from the pressure accumulator into the servo pressure circuit, and wherein the throttle element limits a supply of hydraulic fluid through a supply line to the pressure accumulator, wherein the servo pressure circuit comprises a manifold two-way solenoid valve, that is actively controllably interconnected between the master brake cylinder and the pressure source and the pressure accumulator, wherein the servo pressure circuit comprises a further manifold two-way solenoid valve, that is actively controllably interconnected between the master brake cylinder and a hydraulic fluid reservoir.
