Pressure cylinder room 81 shown in referring to shown in Fig. 5, the 6th oilhole 124, second oilhole 51, between annular valve block 60 and valve seat body 50, the 4th oilhole 53, store up fluid chamber 101 and form a path.

Refer to shown in Fig. 1, when piston rod (not shown) is downward, the working fluid in pressure cylinder room 81 is subject to the area effect of piston rod, causes working fluid to flow downward (extruding).Because the 3rd runner 52 closed by feather valve assembly 120, therefore working fluid can only be drained from the runner of the 5th runner 111 and/or the 6th runner 124.

Refer to shown in Fig. 5, the 5th runner 111 of the present utility model, hollow shaft 10, first flow 11, the 4th runner 53, storage fluid chamber 101 form a path.At a slow speed time, the pressure of working fluid is little (flow is little), feather valve assembly 120 can be fastened because the 6th runner 124 has preload pressure unit (the wave mode pad 122 shown in Fig. 1), therefore working fluid can only pass through via the 5th runner 111, and then flows into storage fluid chamber 101.What the energy that this flow velocity produces claimed is slow rate.

Refer to shown in Fig. 6, when speed becomes large (at a high speed), when the pressure of working fluid becomes large (many), 5th runner 111 cannot completely oil extraction time (because the 5th runner 111 is only single hole), unnecessary energy (time further large), drains the oil duct by means of the 6th runner 124, touches valve block 60 and moves down (unlatching), now, damping force can be produced.6th runner 124, second runner 51, between valve block 60 and valve seat body 50, the 4th runner 53, store up fluid chamber 101 and form a path, working fluid can flow into storage fluid chamber 101 by the 6th runner 124.

So no matter working fluid is the passage via the 5th runner 111 or the 6th runner 124, there is energy in capital, wherein, owing to there is no resistance via the passage of the 5th runner 111, therefore energy is less, as for the passage via the 6th runner 124 owing to then needing certain energy, just can actuate valve block 60, therefore be high-energy.This object is to illustrate, the size of said mechanism damping force adjustable energy, also, and low speed and energy at a high speed.

Refer to shown in Fig. 5, when rotation the first adjusting knob 20, needle-like valve 30 can be made to rise or decline, to adjust the relative distance of needle-like valve 30 and the 5th runner 111, the distance of needle-like valve 30 and the 5th runner 111 is made to open or close, also namely, the sectional area of the 5th runner 111 can be changed, change the size of the 5th runner 111.Shown in Fig. 3, because the cross section of projection 22 presents corresponding Hexagon with the cross section of shrinkage pool 211, therefore when rotation the first adjusting knob 20, can rotate by Timing Belt follower link 21.

When needle-like valve 30 advances towards the 5th runner 111, the sectional area of the 5th runner 111 diminishes, the flow velocity of working fluid is restricted, the flow of low speed will be changed, and make the pressure (energy) of working fluid become large, pressure does not now reach preset pressure and the flow velocity of the 6th runner 124 yet, therefore can only circulate via the 5th runner 111, although pressure now becomes large, be also only limitted to flow slowly, title be slow rate.Therefore, this passage is mainly regulating energy at a slow speed.

Refer to shown in Fig. 6, when high speed (when piston movement is accelerated), the flow of working fluid is large, when the passage of the 5th runner 111 is not enough to absorb energy, the accumulation of energy will be gradually large, when energy savings is to (the k value of elastic component 70 is larger, and predefined value is larger) during a predefined value, shake-up valve block 60 is moved down (unlatching), to carry out the balance (elimination) of energy.This transition point (critical value) touching the energy of valve block 60 is called high pressure.This mechanism is high speed energy, the adjustment of this mechanism is the Hooke's law characteristic via elastic component 70, the strength of elastic component is directly proportional to displacement, and compression elastic piece 70 reaches the principle of high strength, and can change the force value (force value at a high speed) of valve block 60 at any time.When force value improves, also will change the size of touching energy, this mechanism is key at a high speed.And affect the force value of valve block 60, and regulate the size of the 5th runner 111, and then change low speed and high speed energy change whenever and wherever possible, be the purpose of this utility model.

Shown in Fig. 4, outer surface due to hollow shaft 10 is provided with a hexagonal embedding part 12, and the engagement portion 422 of clipping device 42 is resisted against a side of embedding part 12, therefore paragraph sense can be formed when rotation the second adjusting knob 40, in addition, clipping device 42 is sticked in embedding part 12, by means of the restriction of its width W, can avoid causing the second adjusting knob 40 to be separated with hollow shaft 10 because excessively rotating the second adjusting knob 40 and the situation come off occurs.

User can adjust aspect as shown in Fig. 5 to Fig. 6 difference needed for actual, or combination aspect.

Refer to shown in Fig. 7, when piston is to (not shown) during top offset, when pressure in pressure cylinder room 81 is less than the pressure in storage fluid chamber 101, working fluid in storage fluid chamber 101 can flow out storage fluid chamber 101 by the 4th runner 53, flow through the 3rd runner 52 again and push the second pad 121, the wave mode pad 122 of feather valve assembly 120 open, and then in feed pressure cylinder room 81, meanwhile, can by the 5th runner 111 feed pressure cylinder room 81.Or piston is filled with low-pressure gas (nitrogenize) to (not shown) during top offset in inside, pressure cylinder room 81, make working fluid quick backflow to pressure cylinder room 81.By means of wave mode pad 122, there is elasticity, therefore there is when oil return the space that the second pad 121 is pushed open, and can because of the elasticity of wave mode pad 122, second pad 121 be playbacked after oil return.

In sum, damp regulating structure provided by the utility model, its structure is not only more tight, compact, and has coaxial two damping force regulating mechanism, the vehicle being applicable to low speed and running at high speed.

More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection domain of the present utility model.
