During using inventive film boxlike second voltage regulation pressure stabilized fixer, combustion gas is from suction nozzle（5）Through main body（6）In bottom
Chamber is from normally opened bottom spool（13）Enter into lower pressure chamber（9）It is interior, lower pressure chamber（9）Interior combustion gas is from hole（8）Enter into main body
（6）On air inlet（7）, flow into main body after inclined hole（6）Upper lumen.Hole（7）With hole（8）Circle diameter it is identical.
One-level pressure regulation explanation：From normally opened bottom spool（13）It is flowed into lower pressure chamber（9）Interior combustion gas quantity is less than or waits
In setting pressure under can be from hole（8）When flowing out combustion gas quantity, pressure spring（12）Will not be deformed, bottom spool（13）No
Blast tube to be entered can be closed, combustion gas to be entered can be continued to flow into.If conversely, flowing into lower pressure chamber（9）Interior combustion gas quantity is big
In setting pressure under can be from hole（8）During the combustion gas quantity of outflow, lower pressure chamber（9）Interior gaseous-pressure constantly can increase,
Gaseous-pressure after increase just promotes lower diaphragm（11）It is deformed, in bellows-type principle, diaphragm, valve element, spring are to be linked to be
A rigid body.So lower diaphragm now（11）Pressure spring will be driven after deformation（12）Make synchronous compression.Cause
Pressure spring（12）Highly shorten drive bottom spool（13）Make in the same direction, equal mobile so as to progressively close off the flow channel of combustion gas.
No matter whether combustion gas flow channel closes, lower pressure chamber（9）As long as interior have gas, it all can be from hole（8）Flow out, if only flowing out
Without inflow, lower pressure chamber（9）Interior gaseous-pressure can decline rapidly, instantly pressure chamber（9）Interior gaseous-pressure is down to and is equal to
Or it is less than pressure spring（12）Initial pressure when, pressure spring（12）Original height is returned to, while driving bottom spool
（13）Open blast tube recovery combustion gas inflow and push power chamber（9）It is interior.
Gas pressure after one-level pressure regulation, no matter inflow gas source pressure is much, flows out lower pressure chamber（9）Combustion
Atmospheric pressure, is all a more stable pressure value.
It is flowed into main body（6）Combustion gas in upper lumen is again from normally opened upper valve core（17）Enter into upward pressure chamber（3）It is interior,
Upward pressure chamber（3）Interior combustion gas is from hole（16）Enter into main body（6）The venthole on top（15）Afterwards, flow out main body（6）, from master
Body（6）Connected outlet nozzle（14）Flow out, by outlet nozzle（14）Flow into gas tank（18）Storage.Hole（15）With hole（16）Circumference
Diameter is identical.
Second voltage regulation, the mechanism of voltage stabilizing are identical with the mechanism of one-level pressure regulation, voltage stabilizing, but due to function, effect it is different, institute
With its structure, some places are incomplete same.Except for the difference that：
The pressure spring of one-level pressure regulation（12）Its initial pressure fixes uncomfortable, and the pressure-stabilizing spring of second voltage regulation（2）
Initial pressure be adjustable, it can manually adjust out the pressure of various different output combustion gas, to meet electromotor
Requirements of one's work.
What is faced due to one-level pressure regulation is bleed pressure, and the scope of pressure change is big, so pressure spring（12）It is initial
Pressure is big；Second voltage regulation is the output gaseous-pressure after adjusting for one-level, and the pressure very little that need to be adjusted, and than source of the gas pressure
Power is more stable, so the pressure-stabilizing spring on two grades（2）Initial pressure manually adjust in any case after all than the tune in one-level
Pressing spring（12）Initial pressure it is much smaller.
Flow into gas tank（18）In combustion gas, by plastic flexible pipe（19）, blender gas transmission pipe joint（20）Flow into blender
Switch valve（23）In taper lower cavity, after internal combustion engine intake valve is closed, in the presence of the indoor back-pressure of mixing, switch is opened
Valve（23）Into collection chamber（26）Mixing interior mix with air.The indoor mixed gas of mixing, beat in engine intake valve
It is inhaled into after opening in cylinder, under high temperature, high pressure, produces that acute combustion is fast quick-fried in the cylinder, promotes the piston fortune in electromotor
It is dynamic, make engine power.Switch valve in bellows-type blender（23）With diaphragm（21）, adjust spring（22）Also connect
Into a rigid body.When blender main body（27）With collection chamber（26）The mixing being collectively forming is indoor, and the pressure of mixed gas is low
When（Now in-engine inlet valve is to open）, adjusting spring（22）In the presence of initial pressure, switch valve（23）Close
Close, block combustion gas and flow into mixing chamber；When blender main body（27）With collection chamber（26）The gaseous mixture of the mixing interior being collectively forming
When body pressure is high（Now in-engine inlet valve is to close）, adjust spring（22）In diaphragm（21）The pressure for being sensed
Lower compression is promoted, as its length is shortened, switch valve is driven（23）It is mobile, gas inlet passage is opened, combustion gas is flowed again
Enter mixing indoor.In switch valve（17）While opening initially enters combustion gas, because the indoor mixture pressure increase of mixing, is
