Embodiment

As Fig. 1, the present invention includes main reversing valve 1, left pilot valve 2, air bag selector valve 3, air bag 4, air bag one-way valve 5, relief valve 6, one-way valve 7, actuator chamber left end cap 8, actuator chamber right end cap 9, driven plunger 10, drive cylinder body 11, piston brace rod 12, booster cavity 13, charged piston 14, booster cavity end cap 15, cooling cylinder sleeve 16, breather check valve 17, exhaust check valve 18, right pilot valve 19, bearing pneumostome 20 and muffler 21; Main reversing valve 1 is installed in the actuator chamber right end cap 9, air bag selector valve 3 and air bag one-way valve 5 are installed in the actuator chamber left end cap 8, air bag 4, relief valve 6 and one-way valve 7 are fixed on the left end cap 8, left side pilot valve 2 and right pilot valve 19 are installed in respectively in actuator chamber left end cap 8 and the actuator chamber right end cap 9, actuator chamber is by actuator chamber left end cap 8 and actuator chamber right end cap 9, drive cylinder body 11 and driven plunger 10 compositions, booster cavity is by supercharging cylinder body 13, booster cavity end cap 15 and charged piston 14 are formed, and piston brace rod 12 passes actuator chamber right end cap 9 driven plunger 10 is connected with charged piston 14; Breather check valve 17 and exhaust check valve 18 are embedded in the booster cavity end cap 15, and cooling cylinder sleeve 16 is in supercharging cylinder body 13 peripheries, and muffler 21 is installed on the cooling cylinder sleeve 16, and bearing pneumostome 20 is installed on the actuator chamber right end cap 9.

When the present invention worked: drive source of the gas and divide two-way, the one tunnel passed to the P1 mouth of main reversing valve 1, and another road passes to the P2 mouth of air bag selector valve 3.Just logical going up when driving source of the gas, main reversing valve 1 and air bag selector valve 3 at first are positioned at right position and upper under the promotion of propellant, in the air bag 4 gases through air bag one-way valve 5 and driving source of the gas together through the P of air bag selector valve ₂Mouth and A ₂Mouth enters the driving rodless cavity, promotes driven plunger 10 and carries out compression stroke.In this trip process, drive the interior gas of rod chamber and be discharged in the cooling cylinder sleeve 16 through main reversing valve 1, gases are discharged through exhaust check valve 18 under the compression of high pressure piston 14 in the supercharging cylinder body 13.When moving to the compression stroke end, driven plunger 10 touches right pilot valve 19, makes the large size guide of main reversing valve 1 and air bag selector valve 3 hold ventilation, and two valves commutate simultaneously.After this propellant enters the driving rod chamber through main reversing valve 1, and the beginning suction stroke: gas is in breather check valve 17 enters supercharging cylinder body 13.In the suction stroke process, air bag selector valve 3 sources of the gas are blocked, and drive the A of the interior gas of rodless cavity through air bag selector valve 3 ₂Mouth and R ₂Mouth all is discharged in the air bag 4, when piston motion is terminal to suction stroke, touch left pilot valve 2, main reversing valve 1 and air bag selector valve 3 large size end gases are released, main reversing valve 1 and air bag selector valve 3 switch to right position and upper respectively once more, carry out compression stroke once more, realize the continuous working in reciprocating mode of pressurized machine.Along with the continuous to-and-fro motion of pressurized machine, the increasing gas of air bag 4 accumulation, when its pressure reached predetermined value, relief valve 6 was opened, and gas is discharged to cooling cylinder sleeve 16 through one-way valve 7 in it, strengthens the cooling to the supercharging cylinder body.Air bag selector valve 3 is connected with the driving rodless cavity, to drive in the rodless cavity gas in suction stroke collects in the air bag 4, compression stroke with air bag 4 in the gas mixture source fill into driving rodless cavity together once more, thereby, also realized saving the purpose of propellant simultaneously to driving the recycling of propellant in the rodless cavity.
