Patent ID: 7731304

Claim:
An electrohydraulically regulatable vehicle brake system ( 10 ) with traction control, comprising a master cylinder ( 12 ), a wheel brake ( 14 ), a hydraulic unit connected ( 16 ) between the master cylinder ( 12 ) and the wheel brake ( 14 ), the hydraulic unit having electromagnet valves ( 22 , 23 , 50 , 54 ) and an externally triggerable pressure generator ( 26 ) for individual-wheel regulation of the brake pressure at the wheel brakes ( 14 ) as a function of an incident wheel slip, an intake conduit ( 52 ) controllable by an intake valve ( 54 ) and connecting the intake side of the pressure generator ( 26 ) to the master cylinder ( 12 ), and a self-aspirating pressure fluid storage unit ( 60 ) connected to the intake conduit and furnishing an aspiration volume to the pressure generator, wherein the pressure fluid storage unit ( 60 ) has a first pressure chamber ( 80 ) filled with hydraulic pressure fluid of the wheel brake, a separator element that is urged by an elastic element ( 88 ) in the direction of a basic position, in which the pressure chamber ( 80 ) filled with hydraulic pressure fluid is at its maximum volume, and a second pressure chamber ( 82 ) ventilated to outside of the pressure fluid storage unit ( 60 ), wherein the separator element ( 70 ) is disposed between the first pressure chamber and the second pressure chamber.
