Technical field

The present invention relates to a kind of gas pressurized device, be applicable to that especially the exhaust of second use actuator chamber saves the gas booster of propellant consumption.

Background technique

The patent No. is that 93202109.3,94248365.0 and 200820030513.7 model utility all is all to be discharged into atmosphere at the end of travel propellant that the actuator chamber internal pressure is still higher, cause a large amount of wastes and the air consumption of propellant of pressurized machine excessive, and then provide higher requirement the power that the air compressor that drives air is provided for pressurized machine.

Summary of the invention

In order to solve the problems referred to above that the pressurized machine pin exists, the present invention proposes can the exhaust of second use actuator chamber to save the gas booster of propellant consumption, for gas booster is equipped with a novel selector valve, selector valve is when position, a left side, source of the gas is connected with the driving rodless cavity, promotes driven plunger and carries out compression stroke; Drive rod chamber and be connected, gaseous emission in it is fallen, because gas pressure is higher than bleed pressure in the rod chamber, so strengthened cooling effect with the cooling cylinder sleeve.Selector valve is when right position, and source of the gas is blocked, and drives rodless cavity and is connected with the driving rod chamber, drives the still higher gas of rodless cavity internal pressure and enters the driving rod chamber, promotes driven plunger and carries out suction stroke.

Technological scheme of the present invention is: second use propellant gas-saving type gas supercharger, form by selector valve, actuator chamber left end cap, actuator chamber right end cap, driving cylinder body, left pilot valve, right pilot valve, driven plunger, charged piston, piston brace rod, supercharging cylinder body, booster cavity end cap, cooling cylinder sleeve, breather check valve, exhaust check valve, muffler and bearing pneumostome.Selector valve is installed in and drives in the right end cap, left side pilot valve and right pilot valve are installed in respectively in actuator chamber left end cap and the actuator chamber right end cap, by the no bar side of driven plunger with the bar side collision is arranged, come the venting of removing heat by catharsis of commutation valve core two ends, thereby control the automatic switchover of selector valve.Actuator chamber is made up of actuator chamber left end cap and actuator chamber right end cap, driving cylinder body and driven plunger, and booster cavity is made up of supercharging cylinder body, booster cavity end cap and charged piston, and piston brace rod passes the actuator chamber right end cap driven plunger is connected with charged piston; Breather check valve and exhaust check valve are embedded in the supercharging end cap, and the cooling cylinder sleeve is in pressurized cylinder body periphery, and muffler is installed on the cooling cylinder sleeve, and the bearing pneumostome is installed on the actuator chamber right end cap.Described selector valve is pneumatic double controlled two-position four way change valve, and selector valve is when position, a left side, and source of the gas is connected with the driving rodless cavity, drives rod chamber and is connected with the cooling cylinder sleeve; Selector valve is when right position, and source of the gas is blocked, and drives rodless cavity and is connected with the driving rod chamber.

The invention has the beneficial effects as follows, propellant in the gas booster rodless cavity has been carried out second use, not only saved propellant, in suction stroke, drive that gas in the rodless cavity has buffer function to driven plunger but also the noise that can reduce driven plunger suction stroke impact drives in latter stage chamber left end cap.
