It is single, high production efficiency.
In a kind of spool of above-mentioned lubricating oil pump, be provided with spring base on the valve body, the ontology against
Portion is round flat structure, the diameter of the butting section be greater than the diameter of the ontology and the butting section and ontology it
Between formed axial step face, one end resilient abutment of the buffer spring is on the axial step face, the buffering
The other end resilient abutment of spring is on the spring base.The purpose being arranged in this way is the abutting contact for making butting section and valve deck
Area is larger, and it is preferable to seal against fuel feed hole effect, and spring base is arranged on valve body, makes the axially mounted position of buffer spring not
Easily displacement, the elastic reaction of buffer spring are preferable.
In a kind of spool of above-mentioned lubricating oil pump, the inner wall of the valve deck is burnishing surface, the butting section
Outer surface is burnishing surface, and the outer surface of the butting section is sealed against on the inner wall of the valve deck.It is arranged in this way
Purpose is to keep valve deck and butting section abutting contact sealing effect preferable, guarantees the validity of the two sealing.
In a kind of spool of above-mentioned lubricating oil pump, the center line overlap of the fuel feed hole, ontology and straight pin three
Distribution.
Compared with prior art, the advantages of the spool of this lubricating oil pump are as follows: structure design is relatively reasonable, simple, to spool and
Fuel feed hole concentricity requires lower, processing and manufacturing more convenient, high production efficiency good to fuel feed hole sealing effect.
