单向/减压阀位于驾驶室下方。 | |
单向/减压阀将机油在行车制动器蓄能器和举倾机构控制阀之间分流。
机油从制动系统活塞泵流向单向阀 (4) 和 (2) 。 单向阀 (4) 允许机油流向端口 (13) 。 端口 (13) 与制动器控制阀和前桥蓄能器接通。 单向阀 (2) 允许机油流向端口 (1) 。 端口 (1) 与制动器控制阀和中心桥蓄能器接通。 连自活塞泵的管路中的压力下降时，单向阀确保蓄能器持续充注。
减压阀 (5) 降低从活塞泵经单向/减压阀流向举倾机构控制阀的机油压力。 这部分降低的压力是操作举倾机构控制阀的先导压力。
如果制动系统活塞泵的压力/流量补偿阀不能正常工作，安全阀 (6) 避免系统压力升高。
可使用排气螺钉 (8) 和 (10) 排放连至制动系统蓄能器的管路中的压力。
测试端口 (9) 与测试管接头连接，从而能够检查制动系统压力。
测试端口 (11) 与测试管接头连接，从而能够检查举倾系统的先导压力。
