变矩器进口安全阀的位置


图 2g00833807

(1) 变矩器进口安全阀
(1A) 安全阀滑阀
(2) 至变矩器的油道
(3) 至伞齿轮壳体的油道
(4) 调整螺钉

变矩器进口安全阀 (1) 位于优先阀中。

变矩器进口安全阀 (1) 限制输送至变矩器的最高油压。 当发动机起动和油温低时,进口安全阀 (1) 旨在防止损坏变矩器。

进口安全阀 (1) 将最大油压限制为 930 ± 35 kPa (135 ± 5 psi)。 当油道 (2) 中的压力超过 930 ± 35 kPa (135 ± 5 psi) 时,滑阀组件 (1A) 向右移动。 此移动允许机油通过油道 (3) 排入伞齿轮壳体。

当压力下降到低于 930 ± 35 kPa (135 ± 5 psi) 时,滑阀组件 (1A) 移回到左边。 此移动挡住油流到排放口。

变矩器进口安全阀的设置可通过转动螺钉 (4) 进行调节。 螺钉可以用锁紧螺母锁定就位。
