Rationale of the BFA/BFB distributor

1,Lubricant delivered from the oil injector starts to drive through the umbrella valve in the BFA/BFB distributor.  

2,When the umbrella valve closes the oil outlet hole, oil pressure forces oil storage block to overcome spring force and lower down,  and the oil cavity starts to store oil.  

3,When BFA/BFB oil storage block arrives at the top of the oil cavity, storing oil by BFA/BFB is completed. 

4,When the oil pump stops supplying oil, the decompression valve is automatically opened to make lubricant in the main oil pipe to  return through the decompression valve. 

5,The system pressure is lowered, the umbrella valve resets and closes the inlet oil, and the  BFA/BFB oil storage block compresses the lubricant in the oil cavity to the the oil outlet port.

1,Oil volume indication: (notes: when oil volume values of all oil  outlets are identical, represented with one oil volume).  

2,Example 1: BFA/BFB-05-02 means 5-position distributor with model of BFA/BFB, oil delivery volume of oil outlets 1, 2, 3, 4 and 5 is 0.2mL/time. 3,Example 2: BFA/BFB-05-53235 means that outlet oil volumes of outlets 1, 2, 3, 4 and 5 of 5-position distributors with model of BFA are 0.5, 0.3, 0.2, 0.3 and 0.5mL/time. 

4,Applicable ambient temperature:-10℃ to 50℃
