单向阀 (3) 安装在歧管 (5) 上。 歧管 (5) 用螺栓固定在动力传动系油泵上。 油道 (6) 包含变矩器和动力传动系油泵润滑段的压力。 油道 (8) 包含操作控制装置的泵段的压力。 单向阀 (3) 允许油道 (6) 的机油补充操作控制装置的泵段的油流。
油道 (6) 和油道 (8) 的油流确保以下系统保持压力：转向、制动和变速器控制。 此过程发生在需要高油流的情况下。
当油道 (6) 的压力大于油道 (8) 的压力时，单向阀 (3) 打开。 当压力过低时，此过程向控制装置发送储备压力。
当优先阀处于优先模式时，单向阀 (3) 打开。 单向阀 (3) 不允许机油从油道 (8) 流到油道 (6)。
