力士乐比例阀的输入压力为零时,输出腔的压力通过比例阀皮圈凸筋间空酸从唇口泄去高压,同时,当比例阀芯所受的弹簧力大于向右的液压力时,比例阀弹簧将比例阀芯推回原始位置,使比例阀芯与比例阀皮圈内孔*分离而*泄压，此时输入输出压力为零，随着输入压力.增大,即左增大,使比例滑阀单向力平衡遭破坏，比例阀芯左移与比例阀皮圈产生间隙形成节流并混合比倒阀常见的故障为:1,输入输出压力同步.2,低压时辅人输出压力同步,高压时输入输出压力正常.3,低压时输入输出压力正常,高压时输入输出压力不正常.,输入压力为零时（不制动时）,输出压力不为零等等.为混合比倒圉工作性能试验示意图.试验时,先将管内的空气排净,然后分别取低,中,高三个压力进行试验,输入辅出压力符合表1所示即为合格.表混合比例阀试验参数表单位，为混合比例闷常见故障和处理方法.混合比例向在拆卸维修过程中,若污染严重,可用变性酒精清诜,然后烘干后装配.橡胶件装配时表面需涂上清洁的制动液,橡胶件不允许被机油,汽油等污染.表2混合比例阀常见故障和处理故障现象对制动性的膨响常见故障处理方法输入输出空载制动时汽车没有.点,比髑阀油封唇口,更换比例闷油封.
