In order to prevent the lower chambers gas leakage, described outer piston is provided with the seal ring that cooperates with piston rod, guarantees motion sealing between outer piston and the piston rod.
For the ease of the inner cylinder body air inlet, the straight muscle of described inner cylinder body is provided with inlet hole.
In order to make the outer cylinder body to-and-fro motion steady, the end of described outer cylinder body is fixed with protecting cover.
After adopting said structure, upper and lower chamber is inflated respectively by one-way valve, unite two into one, the gas that is produced can be stored in the air storage interlayer of double shell cylinder cylindrical shell, the air storage interlayer plays the effect of high pressure gas bag, characteristic with dual gas cylinder, though piston not aerogenesis can not have influence on another pistons work yet; Have rational in infrastructure, advantages such as gas production is big, pressure is high, dual inflation.
