The metal adapter sleeve threaded connection of the end of bar 1, operating valve system is enclosed in intermediate sleeve 9 by end mechanism riveting, piston valve system 20 with
Intermediate sleeve 9 is threadedly coupled.Orifice valve the whole series valve system is positioned in the working cylinder 2 of shock absorber, and working cylinder 2 is divided to for upper and lower two
Chamber, moved up and down by piston rod 1 and drive valve to work.
Dynamic valve system includes upper end capping 5, adjustment thimble 7, electromagnet 8, movable valve plug 10, and movable valve plug 10 includes movable valve plug spring
The seat of honour 11, movable valve plug spring 12, movable valve plug spring lower seat 13, movable valve plug bottom valve system 14, dynamic thimble 17, dynamic thimble spring 16, on
End seal lid 5 and electromagnet 8 are assembled to outside the upper end of intermediate sleeve 9, pass through the lower end metal adapter sleeve of piston rod 1 and the screw thread of intermediate sleeve 9
Clamp, adjust thimble 7 and movable valve plug 10 is assembled to the inner upper end of intermediate sleeve 9, pass through the work in movable valve plug spring 12 and intermediate sleeve 9
To make the riveting of valve system to be encapsulated in intermediate sleeve 9, adjustment thimble 7 applies pretightning force by the movable valve plug spring seat of honour 11 to movable valve plug spring 12,
Dynamic thimble 17 can be moved up and down with servo valve system after powered up, and dynamic thimble spring 16 aids in dynamic thimble 17 to reset.
The top of intermediate sleeve 9 is divided into the offer motion of movable valve plug 10 and supplies guide space, and bottom is divided into operating valve system offer fluid and led to
Road, the uniform 8 fluid normal opens hole of its side wall, end and middle outer processing screw thread are used for metal adapter sleeve and the work for connecting piston rod
Dynamic valve system and the riveting of operating valve system are encapsulated in inside intermediate sleeve by plug valve system 20, the bottom of intermediate sleeve 9.
Operating valve system includes excessive valve seat 18 and float valve 19, has normal open hole and dynamic thimble 17 to seal among excessive valve seat 18
Hole, normal open hole allow oil to gang up the top of movable valve plug 10, ensure that movable valve plug 10 moves accurately and reliably, move the sealing hole of thimble 17 when dynamic valve
Fluid string ensures that the excessive oil pressure of valve seat 18 is consistent to the excessive outside of valve seat 18 when core 10 moves, and improves Adjustment precision；It is another to cross bottom valve
The seat uniform 8 damping force normal opens hole in 18 ends, in no power, upper and lower cavity fluid is by producing damping force, in the adjustment He of thimble 7
