Embodiment one.
As in Figure 2-4.
A kind of gas spring that driving force is external, it mainly can be for hydraulic cylinder, cylinder etc. by cylinder body 1(), piston 2, piston rod
3, shut-off valve 4 and power cylinder or tank 5 form, as shown in Fig. 2, the medium in the cylinder body 1 be oil liquid body, it is water, aqueous solution, each
Kind one of gas or gas-liquid mixture, can also be identical with existing gas spring, and piston 2 is mounted in cylinder body 1, piston rod

Formula structure can also be monolithic construction), valve button 7 is pressed, valve button drives operating stick to move down, and operating stick pushes cut-off
Valve makes the intracorporal rod chamber of cylinder be connected with rodless cavity；Power piston 8, power piston 8 are installed in the power cylinder or tank 5
Storage chamber 9 and the compressible power cavity 10 of medium will be divided into inside power cylinder or tank, the medium in the power cavity 10 be with
The identical high pressure gas (such as argon gas) of existing gas spring or gas mixture；Storage chamber 9 passes through the sky on pipeline and piston rod 3
Chamber is connected, which is located at the intercommunicating pore 11 that connection cylinder body rod chamber is offered on one end of cylinder body 1；The intercommunicating pore 11
Positioned at the top of stopper rod, and it need to guarantee that the intercommunicating pore is still located in cylinder body under 3 longest stretching state of piston rod.Gas of the invention
Spring back pressure device is as shown in figure 3, pop-up state is as shown in Figure 4.During back pressure and pop-up, shut-off valve 4 be should be at
Opening state, the opening state can be accomplished by pressing valve 7.
When piston rod 3 is in position shown in Fig. 3, by depressing valve button 7, shut-off valve 4 is opened, the oil in rod chamber
Liquid, water and aqueous solution, gas or gas mixture are flowed to rodless cavity, at this time in the power cavity 10 in power cylinder or tank 5
High pressure gas (or high-pressure oil gas mixture) propulsion power piston 8 be moved to the left oil liquid body, the water and water-soluble in storage chamber 9
Liquid, gas or gas mixture be pushed into the rod chamber of cylinder body 1 and flow through shut-off valve and enter no bar by the cavity on piston rod 3
In chamber, piston 2 rises, piston 2(hydraulic cylinder piston or cylinder piston) push piston rod 3 that resistance is overcome to rise, until piston moves
The suffered resistance moved onto top or piston rod is equal with the maximum thrust of gas spring, and piston rod stops rising, and unclamps valve
Button 7, shut-off valve 7 are closed, and the medium in cylinder body rod chamber and rodless cavity can not flow, piston lever lock column.
When needing back pressure, it is again turned on shut-off valve, piston rod pushes under external force, and band piston moves down,
Flow media (such as oil liquid body, water and aqueous solution, gas or gas mixture) in rodless cavity is squeezed into rod chamber, with pressure
Increase, the flow media (such as oil liquid body, water and aqueous solution, gas or gas mixture) in rod chamber is by piston rod
Gas in cavity flows into the storage chamber 9 of power cylinder or tank 5 and propulsion power piston 8 moves right compression power chamber 10 or
Gas-liquid mixture is allowed to generate high pressure, as shown in figure 4, the rising for next piston rod provides power.
As shown in Figure 1, gas spring is mainly made of valve seat, piston rod and the valve rod etc. in cylinder barrel, cylinder barrel, storage in cylinder barrel
There are high pressure gas or gas mixture and oil liquid body (or water and aqueous solution).The working principle of gas spring is the pressure in sealing
It is filled with inert gas or gas mixture in cylinder, so that the intracorporal pressure of chamber is higher than the manyfold of atmospheric pressure, utilizes rodless cavity
The oily cross-sectional area of touching subtracts the pressure difference of the oily cross-sectional area of the touching i.e. cross-sectional area generation of piston rod of rod chamber to realize piston
The pop-up campaign of bar.Gas, the oil circuit of lockable gas spring link up rod chamber and rodless cavity by shut-off valve.When pressing valve is pressed
When button, shut-off valve is opened, and piston rod stretches out；When release button, valve is closed, and spring will be locked.Gas spring is due to piston rod
The volume in cylinder barrel has been occupied, has loaded the external force on piston rod, when compression back pressure works, piston rod is pressed into cylinder barrel, piston rod
It is axially moved in cylinder barrel and squeezes oil liquid body (or water and aqueous solution), and oil liquid body (or water and aqueous solution) pushes piston pressure
Contracting gas reaches operating position；After the external force of load on the piston rod disappears, then gas is restored and is expanded, and the gas of expansion pushes away
Piston resets oil liquid body (or water and aqueous solution), and piston rod is removed, and gas spring is made to realize the movement of compression back pressure and restore
Pop-up movement.
As shown in figure 4, the ejection process of the piston rod of gas spring of the invention is pop-up power F (pop-up) with its piston
Push rod constantly releases elongation and progressively decreases to minimum point to longest point, and changes linearly a process of decline；It is bearing
When external pressure back pressure, back pressure resistance F (back pressure) as its piston push rod is constantly contracted to most short point and constantly rise to highest
Point, and change linearly a process of rising；It is identical in piston push rod with back pressure resistance F (back pressure) to pop up power F (pop-up)
Scalar is equal in magnitude when position, but vector is opposite；For same branch gas spring, power F (pop-up) and back pressure resistance F are popped up
The size of (back pressure) is to be determined by inside of air spring inner gas pressure size, while it causes institute when the up and down motion of its piston push rod
Medium volume changes in rod chamber, changes the closed high pressure gas of inside of air spring (or gas mixture) volume therewith,
Ultimately cause pop-up power F (pop-up) and back pressure resistance F (back pressure) linearly down or up variation, the maximum value of this power and most
The ratio between the ratio between small value and the maximum value of the closed high pressure gas of inside of air spring (or high-pressure oil gas mixture) volume and minimum value
It is in a linear relationship；It is briefly exactly the closed high pressure gas of inside of air spring (or the high pressure in the identical situation of remaining condition
Gas mixture) volume is bigger, where it is caused when piston push rod moves up and down in rod chamber when medium volume variation to gas bullet
Closed high pressure gas (or high-pressure oil gas mixture) volume change is smaller inside spring, pops up power F (pop-up) and back pressure resistance F
The maximum value and minimum value linear change of (back pressure) are with regard to smaller, then in the case where loading constant, when back pressure, exerted forces are just
Smaller, user is lighter, especially in the biggish occasion of duty factor.The closed high pressure gas of inside of air spring in practice
Body (or high-pressure oil gas mixture) volume exactly corresponding gas spring outer dia that becomes larger becomes larger or gas spring extended length, but existing
That there are installation sites is narrow for the special occasion of some in reality, and gas spring outer dia cannot become larger and gas spring length cannot
The case where lengthening, the maximum value and minimum value linear change of traditional gas spring pop-up power F (pop-up) and back pressure resistance F (back pressure)
It is big as a result, especially in the biggish occasion of duty factor, back pressure, exerted forces are just very big in the case where loading constant, make
User is just very laborious, operates extremely inconvenient and humanized.At this moment it is contemplated that whether there is also the installation such as second even third is empty
Between, using external gas storage (tank) cylinder formula gas spring of the present invention, it is suitble to sky in original narrow the first installation space installation
Between relatively gas springs, in second even external gas storage of installation spaces (tank) cylinder, gas spring and external gas storage (tank) cylinder such as third
Between with pipeline seal be connected, the closed high pressure gas of gas spring (or high-pressure oil gas mixture) volume just becomes larger, so both
Solve the installation question of gas spring, but make gas spring pop-up power F (pop-up) and back pressure resistance F (back pressure) maximum value with
Minimum value linear change is small (can theoretically be infinitely close to one), in the case where loading constant, especially compares in load
Big occasion, exerted forces are with regard to very little when back pressure, and just very easily, operation is extremely convenient and hommization, user experience pole by user
It is good.
Under reality, gas spring value of elastic F is rod areas S multiplied by closing high pressure gas therein (or high pressure oil
Gas mixture) pressure P value.That is:
When being ejected into piston rod stretching longest:
F (pop-up)=S(piston rod) * P(pop-up)
Back pressure is stretched out most in short-term to piston rod:
F (back pressure)=S(piston rod) * P(back pressure)
And under conditions of temperature remains unchanged, when same closing high pressure gas (or high-pressure oil gas mixture), high pressure gas (or
High-pressure oil gas mixture) divisor of volume V of pressure P value and high pressure gas (or high-pressure oil gas mixture) is constant E.That is:
P(back pressure)/V(back pressure)=E
P(pop-up)/V(pop-up)=E
So P(pop up) with P(back pressure) size relation are as follows:
P(back pressure)/P(pop-up)=V(pop-up)/V(back pressure)
That is cylinder barrel is occupied and released to piston rod when gas spring is stretched out most in short-term when piston rod stretches out longest with piston rod
Interior volume has pushed the movement of piston, the volume of the high pressure gas (or high-pressure oil gas mixture) of closed storage in cylinder barrel
Change with piston motion, when volume change is violent, P(pop-up) with P(back pressure) size relation ratio will be very big, work as body
When product variation is small, P(pop-up) with P(back pressure) size relation ratio will be very slight, this variation is actually piston rod
The amount V(for stretching out the maximum medium (oil liquid body, water and aqueous solution, gas or gas mixture) most squeezed out in short-term is squeezed
The volume V(of the high pressure gas (or high-pressure oil gas mixture) of closed storage is popped up in cylinder barrel when out) and piston rod stretches out longest)
Variation relation:
V(pop-up)=V(back pressure)+V(squeezes out)
When gas spring stroke and constant diameter of piston rod, V(is squeezed out) it is invariable
So as long as external gas storage (tank) cylinder volume V is sufficiently large:
V(back pressure)/V(squeezes out)=infinitely great
V(is squeezed out) it is relatively infinitely small
V(pop-up) ≈ V(back pressure)
So:
P(pop-up) ≈ P(back pressure)
That is:
F(pop-up) ≈ F(back pressure)
So when installation site is limited, V(back pressure) be limited, cannot accomplish it is comparable big, so back pressure resistance F (back pressure)
It is larger with pop-up power F (pop-up) difference, it is extremely inconvenient and humanized；When use external gas storage (tank) cylinder formula gas bullet of the invention
When spring, V(back pressure) it can accomplish comparable big, it back pressure resistance F (back pressure) and pops up power F (pop-up) and is mutually closer to, user
Just very easily, operation is extremely convenient and hommization, user experience are splendid.
