变矩器进口安全阀 (1) 和变矩器出口安全阀 (2) 均安装在变矩器壳的外部。 两个安全阀的工作原理相同。
变矩器进口安全阀 (1) 控制流入变矩器的最大机油压力。 供往变矩器的机油从变矩器充油泵段流出， 流经变矩器液压滤清器。 进口安全阀确保流入变矩器的最大机油压力不超过 930 ± 35 千帕 (135 ± 5 磅/平方英寸)。

如果是冷态机油，变矩器的进口压力不得超过 930 千帕 (135 磅/平方英寸)。 高于最大设置的压力会损坏变矩器。 |
变矩器出口安全阀 (2) 控制变矩器内的最大机油压力。 机油从变矩器流经通道 (8) ， 然后流过滑阀 (9) ， 最后从通道 (10) 流出。 流出的机油流经变矩器和前制动器冷却油滤网， 与从停车和辅助制动器阀流出的机油汇合， 然后一起流入变矩器和前制动器冷却分流阀。 分流阀引导机油流经变矩器和前制动器机油冷却器，或绕过机油冷却器。 接着，机油会被输送至前制动器。 机油从前制动器流出后，会流回液压油箱。
出口安全阀确保变矩器内的机油压力不超过 345 ± 15 千帕 (50 ± 2 磅/平方英寸)。 部分机油会从出口安全阀流至泵传动装置进行润滑。
