| • Oil volume indication: (notes: when oil volume of all oil outlets are identical,represented with one oil volume). | •油量指示：（注：当所有出油口油量值相同时，以一份油量表示）。 |
| • Example 1: BFG-05-1 means that the oil volume of the 1st,2nd,3rd,4th and 5th oil outlet of the BFG type 5-port distributor is all 0.1mL/time. | • 例1：BFG-05-1 表示BFG 型五通分配器的第1、2、3、4、5 个出油口出油量均为0.1mL/次。 |
| • Example 2: BFG-05-1610050303 means that the oil volume of the 1st,2nd,3rd,4th and 5th oil outlet of the BFG type 5-port distributor is 0.16,0.1,0.05,0.03,0.03,0.03mL/time respectively. | • 例2：BFG-05-1610050303 表示BFG 型五通分配器第1、2、3、4、5 出油口出油量分别为0.16、0.1、0.05、0.03、0.03 mL/次。 |
| • Example 3: BFG-05-10-S means that the oil volume of the 1st,2nd,3rd,4th and 5th oil outlet of the BFG type 5-port distributor is all 0.1ML/time,and one end of the oil inlet main pipe is matched with a pipe and an official cap; One end of the oil outlet pipe is equipped with a plug. | • 例3：BFG-05-10-S表示BFG型五口分配器第1、2、3、4、5出油口出油量均为0.1ML/次，一端进油主管配有管子和官帽；出油管一端 装有堵头。 |
| 【Rationale of the BFE distributor】 | 【BFG 分配器的基本原理】 |
| • The lubricating oil delivered from the oil pump starts to push upward through the umbrella valve in the BFG distributor. | • 从油泵输送的润滑油开始通过BFG 分配器中的伞阀向上推动。 |
| • When the umbrella valve closes the central hole of the core rod, the piston is forced to rise against the spring force,Drain the lubricating oil previously stored in the upper chamber. | • 当伞阀关闭芯杆中心孔时，活塞克服弹簧力而上升。排空上室先前储存的润滑油。 |
| • When the piston moves to the top of the upper chamber,the oil discharge is completed at same time. | • 当活塞运动到上腔顶部时，同时完成排油。 |
| • When the oil pump stops supplying oil,its pressure relief valve opens automatically,so that the pressure oil in the main oil pipe reset to the oil through the pressure relief valve. At this time,the system pressure drops,and the piston in the distributor and enters the oil, the piston presses the lubricating oil stored in the lower chamber to the upper chamber through the small hole of the core rod, and the next fuel supply is also ready. | • 当油泵停止供油时，其泄压阀自动打开，使主油管内的压力油通过泄压阀恢复为油液。此时系统压力下降，分配器内的活塞在弹簧的作用下开始恢复。当伞阀复位关闭分配器并进油时，活塞将下腔储存的润滑油通过芯杆的小孔压到上腔，下一次供油也准备好了。 |
