A valve unit for an anti-deadlock brake system includes a valve body (10, 110), a shut-off piston (18, 118) movable in an interior cavity (22) of the valve body, a plurality of sliding contact seals disposed at an interface between the shut-off piston and the interior cavity. The interior cavity may hydraulically connect a delivery port (14) to the brake caliper, the inlet conduit (20), and the expansion chamber (33). The seal, together with the shut-off piston and the internal cavity, defines an axially movable hydraulic chamber (15, 115). The shut-off piston is movable between a first position in which the hydraulic chamber is in fluid communication with the expansion chamber and the delivery port and not in fluid communication with the inlet conduit, and a second position in which the hydraulic chamber is in fluid communication with the delivery port and the inlet conduit and not in fluid communication with the expansion chamber.

    一种用于防死锁制动系统的阀门单元包括阀门本体(10、110)、可在阀门本体的内部空腔(22)中移动的切断活塞(18、118)、配置于切断活塞与内部空腔之间界面处的多个滑动接触密封件。内部空腔可液压式连接输送端口(14)而至制动卡钳、入口导管(20)、及膨胀室(33)。密封件系连同切断活塞及内部空腔界定可轴向移动液压室(15、115)。切断活塞可在液压室流体连通膨胀室及输送端口且不流体连通入口导管的第一位置、与液压室流体连通输送端口及入口导管且不流体连通膨胀室的第二位置之间移动。
