典型的伺服阀由永磁力矩马达、喷嘴、档板、阀芯、阀套和控制腔组成(见图)。当输入线圈

时,档板向右移动,使右边喷嘴的节流作用加强,流量减少,右侧背压上升;使左边喷
嘴节流作用减小,流量增加,左侧背压下降。阀芯两端的作用力失去平衡, 阀芯遂向左移动

。高压油从S流向C2,送到负载。负载回油通过 C1流过回油口,进入油箱。阀芯的位移量与
力矩马达的输入电流成正比,作用在阀芯上的液压力与弹簧力相平衡,在平衡状态下力

矩马达的差动电流与阀芯的位移成正比。如果输入的电流反向,则流量也反向。表中是伺服
阀的分类。
伺服阀主要用在电气液压伺服系统中作为执行元件(见液压伺服系统)。在伺服系统中,液
压执行机构同电气及气动执行机构相比,具有快速性好、单位重量输出功率大、传动平稳、
