Description
Technical field
The invention belongs to air pump technical fields, and in particular to a kind of inner circulating air pump that can exchange disengaging gas.
Background technique
With the development of auto industry technology, in order to enhance the comfort and stationarity in vehicle travel process, air is outstanding
Frame system is widely applied.It buffers the vibration from wheel using air spring, and adjusts air in real time according to road conditions
The tolerance of spring changes the height of air spring according to this, achievees the purpose that height of the carbody is stable.
In practical applications, by the charge and discharge gaseity of electromagnetism Vavle switching air spring.When air spring needs to increase, electricity
Magnet valve opens it and inflates branch, and after air pump sucks outside air, pressurization indentation air spring completes gas replenishment process；Work as air
When spring needs to reduce, then solenoid valve opens its deflating valve, and portion gas is arranged into atmosphere.In the above process, it is vented space-time
Partial high pressure gas is directly discharged into atmosphere by gas spring, and when inflation needs air pump to pressurize again again the atmosphere of sucking, this
The working strength of air pump is increased to a certain extent, extends the working time, has both affected relaxing for vehicle to a certain extent
Adaptive, and cause energy waste.
Then, people begin look for a kind of energy-saving scheme, can store the gas of air spring discharge, then pressurize the gas
Body inflates air spring.Chinese utility model patent 201621151035 discloses a kind of based on mechanical height valve Vehicular air
Pressure-air is stored in gas supply air accumulator 5, when air spring 7 needs to increase, by supplying by suspension closed-loop control device
Air accumulator 5 is the inflation of air spring 7 by mechanical height valve 6, extra in air spring 7 when air spring 7 needs to reduce
Gas then enters in circular buffering tank 9 through mechanical height valve 6, when the pressure of circular buffering tank 9 reaches predetermined value, then opens gas
Pump 1 supplies the gas indentation in circular buffering tank 9 in air accumulator 5, in case using again to inflate to air spring 7.Although
Such plenum system avoids the gas in air spring and is directly discharged into air, saves the energy of high pressure gas to a certain extent
Source, but structure is more complicated, and the aeration speed of air spring is slower.
It is outstanding that Chinese invention patent application 201810091836.5 discloses a kind of passenger car electronics that gas source self-loopa utilizes
Frame system is still 4 tonifying Qi of gas outlet without changing air pump 184, and gas outlet 4 is the essence of each air bag 6,8,10,13 inflation.

The one-way control valve of form does not do specific requirement to its structure as long as can be realized unidirectionally controlled.Above-mentioned second one-way valve
31 structure no longer specifically repeats herein with aeration valve 15.
The course of work of the invention is as follows:
The internal circulation pump is used in airsuspension system, and the first gas nozzle 4 is for connecting air accumulator, and the second gas nozzle 3 is for connecting
Connect air spring.When air spring, which needs to reduce, to be adjusted, control second solenoid valve 10 is in off-position, and spool 42 exists at this time
Under the support of first spring 47, it is separated from valve seat 45, so that valve nozzle 37 stretches out, on the second gas nozzle 3, by the 4th air flue 8
Isolation block, air spring discharge gas can only by the second gas nozzle 3 enter spool 42 venthole 43 in, from valve seat
45 disengaging position enters in air channel 40, reaches at air passing hole 44, and third air flue 29 is entered from air passing hole 44, opens the gas
Second one-way valve 31 in road, into low pressure chamber 14, motor 13 drives piston rod 18 to pull out, and air pressure reduces suddenly in cylinder barrel 16,
Air intake control valve 21 is caused to open, the gas in low pressure chamber 14 enters the air inlet 20 on piston 19, into the work of cylinder barrel 16
Chamber, the volume to working chamber do not continue to increase, when air pressure remains basically stable in the air pressure and low pressure chamber 14 of working chamber, air inlet control
Valve 21 is closed；When piston rod 18 is pushed back, the volume of working chamber reduces, and interior gas is compressed, waits and reach some strength
Shi Ze opens leaving air control valve 23, is pressed into high pressure chest, and at this time since the 4th air flue 8 is obstructed, gas can only be into high pressure chest
Enter the first high pressure chest 11, reached at the first solenoid valve 9 by the second air flue 7, the first solenoid valve 9 of control must be electric, and spool 42 exists
Under the action of electromagnetic force, overcome the elastic force of the first spring 47 to movement at valve seat 45, venthole 43 is blocked on valve seat 45, valve
Mouth 37 is detached from the connection with the first gas nozzle 4, loses the isolation blocking effect to the second air flue 7, so that high pressure gas enters first
Gas nozzle 4, is discharged in air accumulator.
When air spring needs tonifying Qi to increase, the first solenoid valve 9 of control is in off-position, and spool 42 is first at this time
Under the support of spring 47, it is separated from valve seat 45, so that valve nozzle 37 stretches out, on the first gas nozzle 4, the second air flue 7 is isolated
It blocks, the gas in air accumulator can only be entered in the venthole 43 of spool 42 by the first gas nozzle 4, from the disengaging with valve seat 45
Position enters in air channel 40, reaches at air passing hole 44, and the first air flue 28 is entered from air passing hole 44, opens the in the gas circuit
Two check valves 31, into low pressure chamber 14, the gas in low pressure chamber 14 is pressed into high pressure chest, at this time due to second by cylinder operation
Air flue 7 is obstructed, and gas can only enter the second high pressure chest 12 in high pressure chest, and the first check valve 32 is opened after drying, passes through
Four air flues 8 reach at second solenoid valve 10, and control second solenoid valve 10 must be electric, and spool 42 under the action of electromagnetic force, overcomes
The elastic force of first spring 47 is blocked on valve seat 45 to movement at valve seat 45, venthole 43, and valve nozzle 37 is detached from and the second gas nozzle 3
Connection, lose the isolation blocking effect to the 4th air flue 8 so that high pressure gas enter the second gas nozzle 3, be filled into air spring
In.
Two-way quick circulation of the gas between air accumulator and air spring in airsuspension system is so realized, in realization
Portion's circulation, avoids the loss of pressure energy, reduces air pump and re-compresses the time that air is air spring tonifying Qi, and is low
Air pressure is also higher than normal pressure in pressure chamber 14, reduces the pressure difference on piston 19, reduces the work stress of piston 19, is both conducive to prolong
The service life of long piston 19, and reduce the power of motor 13.
When air spring does not need to do height adjustment, the solenoid valve on air spring is in close state, the first electromagnetism
Valve 9, second solenoid valve 10 and cylinder are in off-position, the disengaging of 3 airless of the second gas nozzle, the first gas nozzle 4 and low pressure chamber 14
It is connected, airless mobilization dynamic.
In above process, the gas in low pressure chamber 14 is less, and when being lower than predetermined value, aeration valve 15 is under the action of pressure difference
It automatically opens, passes through the tonifying Qi into low pressure chamber 14 of gas filling mouth 5；When air pressure in high pressure chest is more than predetermined value, pressure limiting valve 2 is pushed up
It opens, carries out release, until being automatically closed lower than predetermined value.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But without departing from the technical solutions of the present invention, according to the technical essence of the invention to above embodiments institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection scope of technical solution of the present invention.
