Before operation, extrusion piston B2 is in piston unit B internal upper part, extrusion piston B2 under the elastic force effect of main spring B4
Pneumatics room B3 is formed between pneumatic unit A is in the smallest state in space.Piston rod B1 fills rod end chamber A4, piston at this time
Rod cavity A4 is not connected to discharge chamber A41, and the big portion piston rod B1 is not in oil supply gallery C1, fuel feeding poppet C2 and replenishing check valve
Fuel feeding ball-type spool C23 and non-return ball-type spool C43 in C4 are respectively under the action of fuel feeding spring C22 and check spring C42
Close fuel feeding poppet C2 and replenishing check valve C4.The triggering rod A21 touched in chamber A2 is closed under the action of touching spring A22
Third air supply channel A13 had both completely cut off touch chamber A2 and rod end chamber A4 and outlet chamber A3.In outlet chamber A3 on reversal valve A31
Reversing valve core A313 closes ventilation mouth A314 under the action of taking a breath spring A312, had both completely cut off air inlet A1 and reversal valve A31 and has connected
Logical first air supply channel A11.Push the promotion spool A333 on valve A33 under the action of push the spring A332 far from reversal valve
A31。
Extraneous gas enters inside pneumatic unit A from air inlet A1 when use.Air inlet A1 is connected in pneumatic unit A
Three channels, are the first air supply channel A11 for connecting reversal valve A31 in outlet chamber A3 respectively, and the second gas supply that connection touches chamber A2 is logical
The penta air supply channel A15 of road A12 and connection distribution openings A9.The gas for flowing to distribution openings A9 needs to be adjusted according to the actual situation
And closure, it be not discussed in detail in the present embodiment.Because reversal valve A31 closes first air supply channel in the initial state
The power of A11, gas can not open reversal valve A31, so gas is flowed to chamber A2 is touched in the case.Gas reaches touching
After in dynamic chamber A2, triggering rod A21 can be moved downward under the influence of gas, and after triggering rod A21 is moved downward, triggering rod A21 is first
Preceding 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 in unit A, one is that connection outlet chamber A3 pushes valve A33, and another is that rod end chamber A4 is led in connection
Fourth air supply channel A14 because being closed in rod end chamber A4 by piston rod B1 at this time, fourth air supply channel A14 is different, then gas is all
It is pushed in valve A33 with being flowed by the third air supply channel A13.Gas is pushed away by pushing 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, which will push, pushes spool A333
It is mobile to the direction reversal valve A31, until pushing spool A333 to resist reversing valve core A313, when the power that gas generates is greater than ventilation bullet
When power caused by spring A312 and push the spring A332, reversing valve core A313 will be pushed by promotion spool A333, allowed and be first pushed forward
The ventilation mouth A314 that movable valve plug A333 is blocked exposes, and mutually supports between spool A333 and reversing valve core A313 because pushing at this time
Firmly, it is arranged in and the outlet passageway A335 on spool A333 is pushed not expose.After the mouth A314 that takes a breath is connected to commutation chamber A32,
Originally obstructed first air supply channel A11 connection, the gas entered from air inlet A1 pass through first air supply channel A11 one after another and enter commutation
In chamber A32, then entered in the B3 of pneumatics room by duplex channel A35.When the power that gas generates in the B3 of pneumatics room is greater than master
When the upward elastic force of spring B 4, extrusion piston B2 is moved downward, while piston rod B1 being driven to move downward.
Piston rod B1 moves downward step there are two tools at this time, and one is downward fortune of the piston rod B1 in rod end chamber A4
It is dynamic, the other 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 spool C23 in fuel feeding poppet C2 by great pressure inflexibly resist fuel feeding valve seat C21, fuel feeding is logical at this time
Road C1 open circuit, while passing through fuel feeding under the pressure of piston rod B1 in the residual gas on the top oil supply gallery C1 or residual oil liquid
Mouth C24 enters replenishing check valve C4, and the non-return ball-type spool C43 in replenishing check valve C4 is by residual gas or oil residues
The pressure of liquid and open, allow this residual gas fraction or residual oil liquid 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 connection is extraneous at the top of rod end chamber A4, then fourth air supply channel A14 becomes access at this time, originally in the third air supply channel
The gas of A13 flowing is provided with a new route selection again, both passes through fourth air supply channel A14, discharge chamber A41 and rod end chamber
A4 is discharged to the external world, and furthermore this route does not hinder, thus fourth air supply channel A14 be connected to when, originally from the third air supply channel A13 into
The gas entered to push chamber A34 all changes its course from fourth air supply channel A14 discharge, and the gas in push chamber A34 is fewer and fewer at this time, gas
The pressure that body generates is also lower and lower, when the pressure of push chamber A34 is defeated by the elastic force of ventilation spring A312 and push the spring A332
When, it pushes spool A333 and reversing valve core A313 that will reply, pushes spool A333 to reclose ventilation mouth A314 truncation first and supply
Gas channel A11 pushes the outlet passageway A335 on spool A333 to be connected to commutation chamber A32, in commutation chamber A32, so that in sky
Gas in pressure chamber B3 can all 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 is squeezed when the power that gas generates in the B3 of pneumatics room is less than the upward elastic force of main spring B4
Piston B2 is moved downward, while piston rod B1 being driven to move downward.
Piston rod B1, which is moved upwards, can generate two steps, and one is upward fortune of the piston rod B1 in rod end chamber A4
It is dynamic, the other is piston rod B1 moving upwards in oil supply gallery C1.When piston rod B1 is moved upwards in oil supply gallery C1,
Fuel feeding ball-type spool C23 in fuel feeding poppet C2 is by great negative pressure, and fuel feeding ball-type spool C23 is detached from fuel feeding valve seat at this time
C21 allows the oil liquid of the lower part oil supply gallery C1 to enter the top oil supply gallery C1 by fuel feeding poppet C2.Oil liquid enters confession from fuel tank
It needs to first pass through before oily channel C 1 and considers oil network E, impurity is filtered out, because any small impurity may all hinder oil supply gallery C1
Circulation or fuel feeding poppet C2 sealing performance.Replenishing check valve C4 still unsealing at this time, both when piston rod B1 declines
Replenishing check valve C4 is opened, fuel feeding poppet C2 is sealed, replenishing check valve C4 sealing, fuel feeding poppet when piston rod B1 rises
C2 is opened.Piston rod B1 in rod end chamber A4 when moving upwards, piston rod B1 can seal up discharge chamber A41, be vented at this time
Chamber A41 and rod end chamber A4 are open close, and both fourth air supply channel A14 open circuit, entered fourth air supply channel from the third air supply channel A13 originally
The gas of A14 enters again in push chamber A34, starts new primary circulation, pushes spool A333 to reversal valve again
Core A313 is mobile.Hereafter, as long as gas is stable always, gas, can be with by the circulation in pneumatic unit A and piston unit B
Piston rod B1 is allowed to pump always, it is continual that oil liquid is outwardly provided.
In addition, bottom during down triggering rod A21 can arrive to after touch chamber A2 enters gas in the initial state
On extrusion piston B2 because at this time in the B3 of pneumatics room without gas pressure, extrusion piston B2 by the very strong elastic force of main spring B4,
Triggering rod A21 is not just being moved down after resisting extrusion piston B2, and triggering rod A21 descending stroke is insufficient at this time can not be complete
Appear the third air supply channel A13.After the pressure that only B3 has when pneumatics room allows extrusion piston B2 to decline, triggering rod A21 just meeting
And then decline, until triggering rod A21 stroke is complete, the third air supply channel A13 is allowed all to manifest.When extrusion piston B2 is replied
It is identical, after both extrusion piston B2 rising touches triggering rod A21, triggering rod A21 is driven to rise segment distance, so that the third gas supply is logical
Road A13 part overlaid.This set, which can allow, enters the gas smooth change of push chamber A34 from touching chamber A2, prevents gas stream
Suddenly big or suddenly small, the violent frequency for changing extrusion piston B2 movement of amount.In actual use, piston rod B1 up and down reciprocatingly may be used
To reach per minute hundred times or surpass thousand times, the suddenly change of air-flow size can influence the discharge of oil liquid at once during exercise,
By this technological means, both the part of triggering rod A21 and extrusion piston B2 can effectively eliminate air-flow size and acutely became with moving
Change " cliff of displacement formula " variation violent in the caused oil liquid oil pump capacity short time, both ensure that the fuel-displaced stabilization of oil liquid was smooth；Together
When no matter gas is to become larger or become smaller suddenly suddenly, this set can play the role of that art is good for strength.
