阀门在初始位置打开。液压油可以不受限制地从通道 流向通道 。通道中的压力同时通过孔 施加在压缩弹簧对面的活塞区域。同时,通过喷嘴向控制阀芯的弹簧加载侧施加压力,并通过通道向先导控制阀中的球 施加压力。
根据压缩弹簧的设置,压力在球的上游和通道中积聚,将控制阀芯保持在打开位置。液压油通过控制阀芯从通道流向通道 ,直到通道中的压力超过在压缩弹簧处设置的压力值并打开球。控制阀芯移动到关闭位置。如果通道中的压力与压缩弹簧处设置的压力值之间存在平衡,则达到所需的减压。
如果通道A中的压力由于执行器的外力作用而进一步增加,则控制阀芯将进一步推到压缩弹簧上。这样,通道A通过控制阀芯上的控制边连接到通道T。如此多的液压油被排放到油箱中,以至于压力不会进一步增加。
弹簧室的先导油返回始终通过端口 Y 的控制管路从外部实现。必须始终确保与油箱的减压连接。压力表连接可以控制通道中的减压。
