The direction of motion using first piston is front and rear, and front is that, away from power output shaft side, rear is close to power output shaft side；
When motor driving first piston travels forward, first piston promotes second piston to travel forward；
When motor driving first piston is moved backward, the air pressure in the second sealed chamber is less than the gas in first annular seal space room
Pressure, second piston is under the active force of both sides pressure difference, and driving second piston is moved to first piston.
10. the gas pressurized device as claimed in any of claims 1 to 8 suitable for flammable explosive gas, it is special
Levy and be, the outer wall of the piston cylinder is provided with least three fin being parallel to each other, and the spacing of abutting fins is not more than
1cm；
It is fixed with a blower fan on the support, the blowing direction of the blower fan is towards the piston cylinder.
