Torque Converter Hydraulic System
变矩器液压系统包括两个阀。 这些阀是进口安全阀和出口安全阀。
变矩器进口安全阀

变矩器进口安全阀 (3) 控制输送至变矩器的最高油压。 变矩器进口安全阀在发动机起动且油温低时还可防止变矩器部件的损坏。 进口安全阀将输送至变矩器的最大压力限制在大约 895 kPa (130 psi)。 该压力不可以调节。 当压力超过 895 kPa (130 psi) 时，油被倾倒到伞齿轮壳体。
变矩器进口安全阀 (3) 位于歧管总成 (1) 和伞齿轮壳体之间。
变矩器出口安全阀

变矩器出口安全阀 (4) 用于保持变矩器中的最小压力。 最小压力设定值约为 290 kPa (42 psi)。 变矩器出口安全阀安装在变矩器壳体左上方。
机油通过进口通道 (6) 进入阀体 (5) 。 机油使滑阀 (11) 克服弹簧 (8) 和 (9) 的力移动。 这将允许过多的油流过出口油道 (7) 。
过多的油从出口安全阀流向动力传动系机油冷却器。 然后，油流向制动器和终传动的润滑回路。
