1、济南装载机http://www.132p.cn/入口单向阀负责从油泵来的高压油经单向阀进入转向器的进油口，其作用是防止油液倒流，致使方向盘自动偏转，造成转向失灵。
Jinan loaders inlet check valve is responsible for the high-pressure oil from the oil pump to the steering gear through the check valve into the inlet, whose role is to prevent reverse flow,resulting in the automatic steering wheel deflection, causing steering failure.

2、安全阀的主要功能是当压力油到达安全阀设定压力时，安全阀打开泄油，提供转向系统压力的安全?；ぁ?br /> The main function of the safety valve when the pressure of the oil reaches the set pressure of the safety valve, open the drain valve, steering system pressure to provide security.

3、济南装载机http://www.132p.cn/双向过载阀主要负责当转向油缸受到外部冲击时，油缸内的压力升高，压力油到达过载阀设定压力时，过载阀打开泄油，对转向油缸实施过载?；?。
Jinan loader when bidirectional overload valve is mainly responsible for steering cylinder when subjected to external shocks, the pressure within the cylinder increases, the pressure valve oil reaches the set pressure overload, overload valve open drain on the steering cylinder implement overload protection.

4、双向补油阀的主要功能是当油缸一腔压力高于过载阀调定的压力时，过载阀卸荷，油缸另一腔的补油阀补油，从而保证了系统不致产生气蚀现象。
Bidirectional up the oil valve main function is when the fuel tank of a cavity pressure is higher than the overload valve tone given pressure, overload valve unloading, fill up the oil cylinder to another oil valve chamber, thus ensuring the system will not generate cavitation.
