    摘要： A brake system that includes a power-actuated service brake and an auxiliary brake that is actuated by muscle power. To achieve a desired characteristic curve of the pedal when the service brake is actuated, a path simulator is provided in a master cylinder. This path simulator has compression springs disposed in a pressure chamber. The pressure chamber is defined by a floating piston with a seat valve, which controls a pressure fluid-carrying connection of the pressure chamber to a pressure fluid reservoir of the master cylinder. The function of the seat valve is dependent on the stroke of a rod piston, which can displace pressure fluid from a first pressure chamber when the auxiliary brake is actuated. The path simulator is active if pressure fluid is not displaced from the first pressure chamber during the actuation of the service brake and therefore the seat valve assumes its open position.

    摘要： A hydraulic vehicle brake system in which normal service brake operation can be carried out by using external hydraulic energy, and in the event of a lack of external hydraulic energy, auxiliary brake operation by muscle power is possible, with a hydraulic transmission that comes from a master cylinder that can be actuated by means of the brake pedal. The external hydraulic energy is stored, for example, in an accumulator with a gas buffer, which can lead to a gas content in the hydraulic fluid for the service brake operation. The system includes a dual-circuit master cylinder associated with those wheel brakes of a vehicle axle that make a higher contribution to the vehicle deceleration and at the same time, cylinder/piston devices are installed between these wheel brakes and their associated service brake valves for the purpose of preventing hydraulic fluid from getting into these wheel brakes from the external energy source. The advantage is that neither gas nor air is carried into the wheel brakes where it could lead to the formation of bubbles in the event of a pressure drop and would be disadvantageous for an auxiliary brake operation by the master cylinder. The cylinder/piston devices increase the operational safety of the vehicle brake system when braking by muscle power.
