Before operation, extrusion piston B2 is in piston unit B internal upper parts, extrusion piston B2 under the elastic force effect of main spring B4
Pneumatics room B3 is formed between pneumatic unit A in the minimum state in space.Now piston rod B1 fillings rod end chamber A4, piston
Rod cavity A4 is not connected with discharge chamber A41, the big portions of piston rod B1 not in oil supply gallery C1, fuel feeding poppet C2 and replenishing check valve
Fuel feeding ball-type valve element C23 and non-return ball-type valve element C43 in C4 is respectively in the presence of fuel feeding spring C22 and check spring C42
Closing fuel feeding poppet C2 and replenishing check valve C4.The touch pole A21 touched in the A2 of chamber is closed in the presence of spring A22 is touched
Third air supply channel A13, had both completely cut off shake-up chamber A2 and rod end chamber A4 and outlet chamber A3.In outlet chamber A3 on reversal valve A31
Reversing valve core A313 closing ventilation mouth A314 in the presence of ventilation spring A312, had both completely cut off air inlet A1 and reversal valve A31 and had connected
Logical first air supply channel A11.Promote the promotion valve element A333 on valve A33 in the presence of push the spring A332 away from reversal valve
A31。
Extraneous gas is entered inside pneumatic unit A from air inlet A1 when using.Air inlet A1 is connected with pneumatic unit A
Three passages, are respectively the first air supply channel A11 for connecting reversal valve A31 in outlet chamber A3, and the second supply that connection touches chamber A2 is logical
The penta air supply channel A15 of road A12 and connection distribution openings A9.Flowing to the gas of distribution openings A9 needs to be adjusted according to practical situation
And closure, it be not discussed in detail in the present embodiment.Because in an initial condition reversal valve A31 closes first air supply channel
A11, the power of gas can not open reversal valve A31, so in the case gas flows to chamber A2 is touched.Gas is reached and touched
After in dynamic chamber A2, touch pole A21 can be moved downward in the presence of gas, after touch pole A21 is moved downward, touch pole A21 elder generations
Front the third sheltered from air supply channel A13 will expose, and gas just flows into the third air supply channel A13.Third air supply channel A13 is pneumatic
Two passes are connected with unit A, one is that connection outlet chamber A3 promotes valve A33, and another is that rod end chamber A4 is led in connection
Fourth air supply channel A14 because now being closed by piston rod B1 in rod end chamber A4, fourth air supply channel A14 is different, then gas is all
Promoted in valve A33 with being flowed into by the third air supply channel A13.Gas is pushed away through promoting the promotion mouth A334 on valve A33 to be flowed into
In push chamber A34 inside dynamic valve A33, when the gas in push chamber A34 is more and more, gas can promote valve element A333
To the movement of reversal valve A31 directions, until promoting valve element A333 to prop up reversing valve core A313, when the power that gas is produced is more than ventilation bullet
During power produced by spring A312 and push the spring A332, reversing valve core A313 will be promoted by promotion valve element A333, allowed and previously push away
The ventilation mouth A314 that movable valve plug A333 is blocked exposes, because now promote mutually being supported between valve element A333 and reversing valve core A313
Firmly, it is arranged on and promotes the outlet passageway A335 on valve element A333 not expose.After the mouth A314 that takes a breath is connected with commutation chamber A32,
Originally obstructed first air supply channel A11 connections, the gas entered from air inlet A1 enters commutation by first air supply channel A11 one after another
In the A32 of chamber, then entered in the B3 of pneumatics room by duplex channel A35.When the power that gas is produced in the B3 of pneumatics room is more than master
During the elastic force upwards of spring B 4, extrusion piston B2 is moved downward, while driving piston rod B1 to move downward.
Now piston rod B1 is moved downward with two steps, and one is downward fortune of the piston rod B1 in rod end chamber A4
Dynamic, another is piston rod B1 moving downward in oil supply gallery C1.When piston rod B1 is moved downward in oil supply gallery C1,
Fuel feeding ball-type valve element C23 in fuel feeding poppet C2 be subject to great pressure inflexibly prop up fuel feeding valve seat C21, now fuel feeding lead to
Road C1 is breaking, while the residual gas or residual fluid on oil supply gallery C1 tops passes through fuel feeding under the pressure of piston rod B1
Mouth C24 enters into replenishing check valve C4, and the non-return ball-type valve element C43 in replenishing check valve C4 is subject to residual gas or oil residues
The pressure of liquid and open, allow this residual gas fraction or residual fluid enter oil discharge passage C3.Piston rod B1 is in rod end chamber
In A4 when moving downward, when piston rod B1 is moved in discharge chamber A41, then the top of discharge chamber A41 and rod end chamber A4
Connection, because the connection of rod end chamber A4 tops is extraneous, then now fourth air supply channel A14 is changed into path, originally in the third air supply channel
The gas of A13 flowings is provided with a new route selection again, both by fourth air supply channel A14, discharge chamber A41 and rod end chamber
A4 is discharged to the external world, and in addition this route does not hinder, so when fourth air supply channel A14 is connected, entering from the third air supply channel A13 originally
The gas entered to push chamber A34 all changes its course from fourth air supply channel A14 discharges, and now the gas in push chamber A34 is fewer and feweri, gas
The pressure that body is produced is also more and more lower, when the pressure of push chamber A34 is defeated by the elastic force of ventilation spring A312 and push the spring A332
When, promote valve element A333 and reversing valve core A313 to reply, promote valve element A333 to reclose ventilation mouth A314 and block first confession
Gas passage A11, promotes the outlet passageway A335 on valve element A333 to connect with commutation chamber A32, in commutation chamber A32, so that in sky
Gas in pressure chamber B3 all can be discharged to silencing means D by outlet passageway A335.Once the gas in the B3 of pneumatics room flows away, then
Insufficient pressure in the B3 of pneumatics room, when elastic force upwards of the power that gas is produced in the B3 of pneumatics room less than main spring B4, extruding
Piston B2 is moved downward, while driving piston rod B1 to move downward.
Upwards athletic meeting produces two steps to piston rod B1, and one is upwards fortune of the piston rod B1 in rod end chamber A4
Dynamic, another is upwards motions of the piston rod B1 in oil supply gallery C1.When piston rod B1 is moved upwards in oil supply gallery C1,
Fuel feeding ball-type valve element C23 in fuel feeding poppet C2 is subject to great negative pressure, and now fuel feeding ball-type valve element C23 departs from fuel feeding valve seat
C21, allows the fluid of oil supply gallery C1 bottoms to enter oil supply gallery C1 tops by fuel feeding poppet C2.Fluid is entered from fuel tank and supplied
Need to first pass through worry oil network E before oily channel C 1, filter out impurity, because any small impurity may all hinder oil supply gallery C1
Circulation or fuel feeding poppet C2 sealing property.Now replenishing check valve C4 still unsealings, both when piston rod B1 declines
Replenishing check valve C4 is opened, fuel feeding poppet C2 sealings, replenishing check valve C4 sealings, fuel feeding poppet when piston rod B1 rises
C2 is opened.During upwards motions of the piston rod B1 in rod end chamber A4, piston rod B1 can seal up discharge chamber A41, now aerofluxuss
Chamber A41 is open close with rod end chamber A4, and both fourth air supply channel A14 was breaking, enters fourth air supply channel from the third air supply channel A13 originally
The gas of A14 is entered again in push chamber A34, starts new circulation once, and valve element A333 is promoted again to reversal valve
Core A313 is moved.Hereafter, as long as gas is stable always, then gas is by the circulation in pneumatic unit A and piston unit B, can be with
Piston rod B1 is allowed to pump always, it is continual that fluid is outwardly provided.
In addition, touch chamber A2 in an initial condition entering after gas, touch pole A21 bottoms during down can arrive to
On extrusion piston B2, because now without gas pressure in the B3 of pneumatics room, extrusion piston B2 is subject to the very strong elastic force of main spring B4,
Touch pole A21 propped up and just down do not moved after extrusion piston B2, and now touch pole A21 descending strokes are insufficient can not be complete
Appear the third air supply channel A13.Only after the pressure that pneumatics room B3 has declines by extrusion piston B2, touch pole A21 just meetings
And then decline, until touch pole A21 strokes completely, allow the third air supply channel A13 all to manifest.When extrusion piston B2 is replied
Identical, both extrusion piston B2 rose and touched after touch pole A21, drove touch pole A21 to rise little segment distance so that the third supply is logical
Road A13 part overlaids.This set can allow from the gas smooth change for touching chamber A2 into push chamber A34, prevent gas stream
Suddenly big or suddenly small, the violent frequency for changing extrusion piston B2 motions of amount.When actually used, piston rod B1's up and down reciprocatingly may be used
To reach per minute hundred times or advanced time, in motion, the suddenly change of air-flow size can at once affect the discharge of fluid,
By this technological means, both the part of touch pole A21 and extrusion piston B2 was same dynamic, can effectively eliminate air-flow size and acutely become
Change " cliff of displacement formula " change violent in the caused fluid oil pump capacity short time, both ensure that the fuel-displaced stable smooth-going of fluid；Together
When no matter gas be to become big suddenly or diminish suddenly, this set can play a part of that art is good for strength.
