Claim 19:
20. A vehicle brake system, comprising:
a hydraulic fluid pump;
a first main cylinder with a first main cylinder connection;
a first actuating device with a first actuating connection and with a first supply connection, the first main cylinder connection being in hydraulic fluid flow-connection to the first actuating connection and the hydraulic fluid pump being in hydraulic fluid flow connection with the first supply connection through a first supply line, and the first actuating device being operable with the first main cylinder;
a pressure relief valve arranged in the first supply line;
a check valve arranged in the first supply line between the first actuating device and the pressure relief valve;
a throttle valve arranged between the hydraulic fluid pump and the pressure relief valve;
a first brake circuit provided between the hydraulic fluid pump and a first wheel cylinder, the first brake circuit including a first accumulator in flow connection with a brake line coupled to the hydraulic fluid pump, the hydraulic fluid pump in the first brake circuit being operable to generate pressure and move a hydraulic fluid within the first brake circuit through the brake line;
a first valve device coupled to the hydraulic fluid pump through the brake line, the first valve device including a through-flow position and a locking position, the first valve device provided in the first brake circuit, the first valve device being movable between a first configuration at the through-flow position in which a first flow connection is produced between the hydraulic fluid pump and the first wheel cylinder, and a second configuration at the locking position in which the first flow connection hydraulic fluid between the hydraulic fluid pump and the first wheel cylinder is prevented;
a second brake circuit provided between the hydraulic fluid pump and a second wheel cylinder, the first brake circuit including a second accumulator in flow connection with a brake line coupled to the hydraulic fluid pump, the hydraulic fluid pump being operable in the second brake circuit to generate pressure and move the hydraulic fluid within the second brake circuit through the brake line; and
a second valve device coupled to the hydraulic fluid pump through the brake line, the second valve device provided in the second brake circuit and being movable between a third configuration in which a third flow connection between the hydraulic fluid pump and the second wheel cylinder is produced, and a fourth configuration in which the third flow connection between the hydraulic fluid pump and the second wheel cylinder is prevented;
wherein, the first valve device is operable with actuation of the first actuating device; and
wherein, the first valve device is movable into the first configuration.
