    • A valve (60) for use in a brake system (10) through which a source (32) of fluid charges an accumulator (24) to a desired fluid pressure level and through which fluid pressure present in a conduit (52) is communicated to a reservoir (33) in the absence of the flow of fluid from the source. The valve (60) has a housing (62) with a bore (64) therein with an entrance port (66) connected to the source of fluid (32), an exit port (68) connected by a flexible conduit (52) to the accumulator (24) and exhaust port (70) connected to the reservoir (33). A sleeve (72) which is located in bore (64) has an internal bore (74) with a first diameter (82) for retaining a first ball (90), a second diameter (80) for retaining a linkage member (94) and a third diameter (86) for retaining a second ball (92). A first spring (93) urges the first ball (90) toward a first seat (84′) formed between the first (82) and second (80) diameters. A second spring (100) urges the sleeve (72) toward a rest position to allow the first spring (93) to seat the first ball (90) on the first seat (84′) to prevent the flow of fluid from the source (32) to the accumulator (24) while allowing free communication between the exit port (68) and the exhaust port (70) to permit fluid pressure in the flexible conduit (52) to be dissipated in the reservoir (33). The communication of fluid from the source (32) to the entrance port (66) developing a force across the sleeve (72) which moves the second ball (90) into engagement with an exhaust port (70) to interrupt communication to the reservoir (33) and allow fluid to flow from the entrance port (66) to the exit port (68) for charging the accumulator (24).
    • 一种用于制动系统(10)的阀(60),流体源(32)通过所述制动系统(10)将蓄能器(24)装载到期望的流体压力水平,通过所述阀(52)将存在于导管(52)中的流体压力传递到 在没有来自所述源的流体流动的情况下,存储器(33)。 阀(60)具有壳体(62),其中具有孔(64),其中连接到流体源(32)的入口(66),通过柔性导管(52)连接到 蓄能器(24)和连接到储存器(33)的排气口(70)。 位于孔(64)内的套筒(72)具有内孔(74),其具有用于保持第一球(90)的第一直径(82),用于保持连杆构件(94)的第二直径(80) 和用于保持第二球(92)的第三直径(86)。 第一弹簧(93)将第一球(90)推向形成在第一(82)和第二(80)直径之间的第一座(84')。 第二弹簧(100)将套筒(72)推向静止位置以允许第一弹簧(93)将第一球(90)安置在第一座(84')上以防止流体从源( 同时允许出口(68)和排气口(70)之间的自由连通,以允许柔性管道(52)中的流体压力在储存器(33)中消散。 从源(32)到入口(66)的流体的连通通过套筒(72)形成力,其使第二球(90)与排气口(70)接合以中断与储存器的连通 33),并允许流体从入口(66)流到出口(68),以对蓄能器充电(24
