A traction-slip-controlled hydraulic vehicle brake system (10) has brake lines (17, 18) running between a dual-circuit brake master cylinder (13) and one wheel-brake cylinder each (19, 20), a cut-off valve (21) in the respective brake line (17, 18), a bypass line (24, 25) bypassing the respective cut-off valve (21) and a pump (30) in the respective bypass line (24, 25) to pump hydraulic fluid from the associated wheel-brake cylinder (19, 20) to the brake master cylinder (13). The pump (30) is designed for pumping hydraulic fluid from the brake master cylinder (13) to the wheel-brake cylinder (19, 20), as well. It is a rotary positive-displacement pump, in particular a vane pump. The pumps (30) in the bypass lines (24, 25) have a common reversing drive motor (38). The vehicle brake system (10) is designed for anti-blocking and automatic traction control operation without additional apparatus. |
