| 摘要 |
The invention concerns a brake-pressure control system which includes an anti-blocking control system (ABS) and/or a drive slip control system (ASR). In order to ensure inexpensively a slip-controlled pressure-decay phase with reduced residual pressure at the brake, the brake system proposed has a brake-pressure control system in which a first piston (1) is fitted inside a second piston (4) which has a step (3) and which is designed to move relative to the valve housing (2). A pair of springs (5, 6) fixed in the second piston (4) contact the first piston (1) as well as an integral closure element (7) in the step zone. |
