A valve unit (10) for an anti-lock brake system has a single hydraulic chamber (15) configured to receive brake fluid, the single hydraulic chamber having a delivery port (14) supplying brake fluid to a brake caliper (G) and a passage (50) allowing brake fluid from a main cylinder (M) to enter the single hydraulic chamber (15). A single piston (18), which is movable in the longitudinal direction within the single hydraulic chamber (15), has a first transverse surface facing the delivery opening and defining a first transverse region as a whole, and has a second transverse surface facing away from the delivery opening (14) and defining a second transverse region as a whole, the second transverse region being larger than the first transverse region. The longitudinal cavity (31) extends in a single piston (18) establishing fluid communication between the first and second transverse surfaces, whereby displacement of the piston towards the delivery port (14) obstructs the passage (50) and increments the volume available for brake fluid in the hydraulic chamber.

    一种用于防抱死制动系统的阀单元(10),具有单一液压室(15),其被配置成接收刹车流体,单一液压室具有输送口(14)以及通路(50),输送口供应刹车流体至刹车卡钳(G),通路让来自主缸(M)的刹车流体进入单一液压室(15)中。在单一液压室(15)内沿纵向可移动的单一活塞(18)具有面向输送口且整体界定第一横向区域的第一横向表面,且具有背对输送口(14)且整体界定第二横向区域的第二横向表面,第二横向区域比第一横向区域大。纵向空腔(31)在单一活塞(18)中延伸,而在第一横向表面与第二横向表面之间建立流体连通,由此,活塞朝向输送口(14)的移位阻隔通路(50)且递增液压室中可用于刹车流体的体积。
