结构：(LFM)进口油管路过滤器由内置压差溢流阀的过滤器头部和旋入式筒体组成 (LFM) inlet oil pipeline filter consists of filter head with built-in differential pressure relief valve and screw in cylinder

功能：进出口的压差控制溢流阀的开启。当通过滤芯的压差升高，例如油粘度变高（冷启动时）或更换滤芯错误，溢流阀开启，一部分流量通过滤器的第三油口回油箱，剩余的流量通过滤器维持系统运行，直至因性能下降而被操作者发现 Function: the differential pressure at the inlet and outlet controls the opening of the relief valve. When the differential pressure through the filter element increases, such as the oil viscosity becomes higher (during cold start) or the filter element is replaced incorrectly, the overflow valve opens, and part of the flow returns to the oil tank through the third oil port of the filter, and the remaining flow maintains the system operation through the filter until it is discovered by the operator due to the performance degradation.
