从而保证P2的增量小于P1的增量，若弹簧3的弹力F不变，则Ps点不变，即比例阀节制后轮管路压力的工作点与汽车的载荷无关，这就是非感载比例阀。若要使其工作点与汽车载荷的大小相适应，就必须能改变弹簧力的大小这就是感载比例阀。感载比例阀及其感载控制机构的原理如图12-10所示，阀体3安装在车架上其中的活塞4右部的空腔内有阀门2。不制动时，活塞在感载拉力弹簧6通过杠杆5施加的推力F的作用下处于右极限位置。阀门2因其杆部顶触螺塞1而开启。

美国派克PARKER 比例阀一般采用两端承压面积不等的差径活塞结构。工作原理如图12-9所示，比例阀不工作时，差径活塞2在弹簧3的作用下处于上极限位置。此时阀门1保持开启，因而在输入控制压力P1与输出压力P2从零同步增长的初始阶段，总是P1=P2。但是压力P1的作用面积为A1=π(D2-d2)/4，压力阀的作用面积为A2=πd2/4，因而A2>A1，故活塞上方液压作用力大于活塞下方液压作用力。在P1、P2同步增长过程中当活塞上、下两端液压作用之差超过弹簧3的预紧力时，活塞便开始下移。当P1和P2增长到一定值Ps时活塞2内腔中的阀座与阀门1接触，进油腔与出油腔即为隔绝。此即比例阀的平衡状态。
若进一步提高P1则活塞将回升，阀门再度开启。油液继续流入出油腔使P2也升高但由于A2＞A1，P2尚未及增长到新的P1值，活塞又下降到平衡位置。在任一平衡状态下，差径活塞的力的平衡方程为：P2A=P1A1+F(此处F为平衡状态下的弹簧力)。
PARKER电磁阀是用来控制流体的方向的自动化基础元件，属于执行器；通常用于机械控制和工业阀门上面，对介质方向进行控制，从而达到对阀门开关的控制。PARKER电磁阀里有密闭的腔，在不同位置开有通孔，每个孔都通向不同的油管，腔中间是阀，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来档住或漏出不同的排油的孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油缸的活塞，活塞又带动活塞杆，活塞杆带动机械装置动。这样通过控制电磁铁的电流就控制了机械运动。唯有电磁阀是用电磁力作用于密封在PARKER电动调节阀隔磁套管内的铁芯完成，不存在动密封，所以外漏易堵绝。电动阀力矩控制不易，容易产生内漏，甚至拉断阀杆头部；PARKER电磁阀的结构型式容易控制内泄漏，直至降为零。

S系列汽车感载比例阀是串联于液压制动回路的后促动管路中的，其作用是为了防止出现后轮先抱死，当前、后促动管路压力Pl与P2同步增长到一定值Ps后，即自动对P2的增长加以节制，亦即使P2的增量小于P1的增量。
制动时，来自主缸而压力为P1的制动液由进油口A进入并通过阀门从出油口B输出至后促动管路。此时输出压力P1=P2。因活塞右端承压面积大于左端承压面积，故P1和P2对活塞的作用力不等。于是活塞不断左移，zui后使其上的阀门接触而达到平衡状态。此后，P2的增量将小于P1的增量。其特点是作用于活塞的轴向力F是可变的。拉力弹簧6右端经吊耳与摇臂7相连而摇臂则夹紧在汽车后悬架的横向稳定杆8的中部。当汽车装载量增加时，后悬架载荷也增加，因而后轮向车身移近后悬架的横向稳定抨便带动摇臂7转过一个角度，将弹簧6进一步拉伸，作用于活塞上的推力F便增大。反之，汽车装载量减小。这样，调节作用起始点控制压力值Ps就随汽车实际装载量而变化。
