Certain circulation between chamber 14 and cavity of resorption 11 be present, the fluid in compensated cavity 14 is entered in cavity of resorption 11, it is compensated, or
Under pressure balance is made, the unnecessary fluid in cavity of resorption 11 enters in compensated cavity 14.
Referring to figs. 1 to Fig. 4, main operational principle of the present utility model is as follows：
When syringe needle 300 is inserted in oil-through hole 203, and oil-through hole 203 is blocked completely, fluid can not pass through oil-through hole
203, the fluid in epicoele 10 and cavity of resorption 11 can only rely on pressure itself balancing damping, and its damping damped coefficient is maximum.
It is and syringe needle 300 when exiting oil-through hole 203 completely under the control of governor motion 4, i.e., non-overlapping with oil-through hole 203
When, now the pasta of crossing of the upper end of oil-through hole 203 accumulates maximum, the damping damped coefficient minimum of damper.
Governor motion 4 controls the length that syringe needle 300 is stretched into oil-through hole 203, so as to change the size of pasta product, makes to subtract
Shake damped coefficient changes between a minimum value and a maximum value, and when damper is in compression work state, it compresses oil circuit stroke 8
As illustrated, the fluid in cavity of resorption 11 enters in epicoele 10 through oil-through hole 203, transfer chamber 310 and tap hole 301, while cavity of resorption
Unnecessary fluid can also be entered in compensated cavity 14 by compression valve 6 in 11, auxiliary compression；
When damper, which is in, resets working condition, it resets oil circuit stroke 7 as illustrated, the fluid in epicoele 10 passes through
Tap hole 301, transfer chamber 310 and oil-through hole 203 enter in cavity of resorption 11, meanwhile, the fluid in compensated cavity 14 passes through compression valve 14
Into in cavity of resorption 11, play a part of quickly compensating jointly.
Adjusted by the multiple rotary of adjusting knob 40, so that relative position is more between syringe needle 300 and oil-through hole 203,
The accurate adjustment of more gears can be realized, improves the practicality of damper.
Finally it should be noted that foregoing description is only preferred embodiment of the present utility model, the ordinary skill of this area
Personnel on the premise of without prejudice to the utility model aims and claim, can make a variety of under enlightenment of the present utility model
Similar expression, such conversion are each fallen within the scope of protection of the utility model.
