压力油由变速箱泵经过供油口 (4) 供应至电子离合器压力控制阀。 允许先导压力经过控制滑阀 (2) 到达腔室 (9) 。 将腔室 (9) 中的机油经过节流孔 (8) 和排流口 (6) 排放到油底壳。
选定一个档位并且电磁阀 (1) 接合时，将钢球 (7) 推向节流孔 (8) 。 腔室 (9) 中的油压升高。 压力升高使控制滑阀 (2) 向右顶着弹簧 (3) 移动。 允许压力油经过离合器加注口 (5) 流入离合器。
当电磁阀 (1) 分离时，腔室 (9) 中的油压使钢球 (7) 脱离。 将腔室 (9) 中的机油经过节流孔 (8) 和排流口 (6) 排放到油底壳。 随着腔室 (9) 中压力下降，控制滑阀 (2) 被弹簧 (3) 移回左侧。 随着控制滑阀返回左侧，供油口 (4) 的供油被阻断。 允许离合器中的机油经过排流口 (6) 流入油底壳。
