Oil mass self-regulation control assembly function declaration in this invention：
1st, in runner during hydraulic oil low pressure, the realization of oil mass self-regulation control assembly function is depending on hydraulic fluid pressure
Change；Enter with impedance screw into initial throttle orifice from hydraulic oil control unit in air bleeding valve ascent stage fluid and connect oil mass
The passage of the control assembly that is self-regulated；Installation of the fluid in the second throttle hole and plug screw in exit in inner chamber is cached is caused
The position pressure for connecting oilhole slowly increases, not by the percussion of high pressure；Material is thus formed periodic pressure change.
2nd, in runner during hydraulic oil low pressure, now spring travel becomes big, the fluid in compression needle shaft oil groove, needle shaft connection
Outlet (oil groove in sliding block), fluid enters sealing oil export from the oil groove in sliding block.
3rd, the hydraulic oil high pressure in runner, sliding block is moved to the left, spring-compressed, and pressure is promoted and indicates pin (guide rod) to the left
Mark, indicate the action of sliding block, while so that Seal Oil port closing, fluid enters in the temporary tank of needle shaft.
4th, during hydraulic fluid pressure decline in runner, while spring recovers its pre-compressed state gradually, sliding block movement makes
Seal Oil outlet, release groove inner fluid, while the fluid into needle shaft is kept in needle shaft slotted eye and do not discharged.
5th, when hydraulic fluid pressure is low in runner, while spring recovers its pre-compressed state, sliding block movement, needle shaft end is temporary
The transmission of needle shaft slotted eye inner fluid is discharged into sliding block temporary tank, and the movement of sliding block causes Seal Oil port closing.
High pressure sealing oil control device of the invention, it is possible to achieve the control to realizing high pressure sealing oil in complex large-sized mechanism
System, while realizing intermittent fuel feeding realizes reliable oil sealing, and has structural-mechanical property stabilization simultaneously, and high temperature resistance is voltage resistance strong
