The working principle of the invention:
Damped valve in structure of the invention realizes cushioning effect by the conversion of electromagnetic motor liquid, particularly a kind of built-in to subtract
Valve is shaken, even if the used time is built-in in the shell of damper, buffer liquid is full of in the shell of damper, in the damping
It is equipped with inlet opening on the top of valve and side wall, fluid hole is equipped in its bottom, is located in the shell by adjusting damper and subtracts
The machine hydraulic pressure difference of valve upper and lower ends is shaken to realize different degrees of damping, improves driving comfort and safety.
As shown in figure 5, being solenoid valves state, coil windings 2 generate magnetic force after being powered, and magnetic force imported into magnetic conductive tube 3
In to form magnetic field force in 3 inner cavity of flux sleeve, armature 5 up moves under the action of a magnetic force, band after armature 5 up moves
Dynamic upper cushion block 7, lower cushion block 8 up move together, at this point, pressing force reduction of the lower cushion block 8 to 9 upper end of poppet valve core, i.e. poppet valve core 9
Under the active force of pre-compressed spring 15, the installation cavity of upper end and lower cushion block 8 forms gap between 8.1 top, then at this point, from
The machine liquid that the path C flows into passes into the valve chamber of solenoid valve seat 6 from inlet opening 3.3 is shunted, under pressure that poppet valve core 9 is past
On open, machine liquid is mixed with the machine liquid in the path A, by deflector hole 6.1 enter throttling valve inlet, until throttle valve outlet outflow；
At the same time, also there is the machine liquid flowed into along B path on the side wall of magnetic conductive tube 3, while entering throttle valve, have
Body, under normal circumstances, the fixed link 23 in throttle valve component is under the effect of 21 elastic force of elastomeric pad in the shape up ejected
State, and the top of fixed link 23 bears against fixing seat 18, so that the bottom surface phase of the upper surface of fixing seat 18 and solenoid valve seat 6
Against can be moved down in the case where receiving pressure above fixed link 23, so if the machine liquid of B path in figure is from magnetic conduction
Enter in inlet opening 3.2 on 3 side wall of pipe, under the action of machine hydraulic coupling, is become by compressive resilience gasket 21 down
Shape, fixing seat 18 move down, and the upper surface of fixing seat 18 and the bottom surface of solenoid valve seat 6 form the gap passed through for machine liquid.
This state, machine liquid flow to throttle valve simultaneously by tri- paths of A, B, C, realize two-way pressure difference quick flat in the cavity of damper
Weighing apparatus, such car is lower in traveling process vibratory sensation, and comfort is high.
As shown in fig. 6, be solenoid valve being off-position, the valve chamber of poppet valve core 9 and solenoid valve seat 6 is locking state at this time,
This opportunity liquid can only enter throttle valve by two paths of A, B, flow out by the outlet of throttle valve, under this state, damping
The speed that two-way pressure difference balances in the cavity of device is slow.
I.e. in practical usage situations, the size of vibration is experienced according to car, that is, evenness of road surface situation is fitted
The shockproof control of answering property, in the case where road surface is seriously uneven, solenoid valve starts, in damper under machine liquid balancing speed,
Car vibration is small, and comfort is good.In the case where evenness of road surface, pressure difference existing for damper upper and lower cavity itself with regard to small, so
It relies only on two paths of A, B and can be achieved with damping effect to carry out pressure balance, opens solenoid valve can not had at this time, keep C
The closing in path.
Preferred embodiments of the present invention are described above, but are not to be construed as limiting the scope of the invention.This hair
Bright to be not only limited to above embodiments, specific structure is allowed to vary, all institutes in the protection scope of demand for independence of the present invention
The various change of work is within the scope of the invention.
