System and method for piston recoil pressure adjustment

A method for piston recoil pressure adjustment, providing a system for on demand piston recoil pressure adjustment, comprising:

• a piston, comprising:
• a first section above a piston head;
• a second section below the piston head;
• and
• a piston rod is configured to move the piston head within the first and second sections of the piston, wherein air is sealed within the piston and can only vent externally through a first vent, and between the first and second section through a second vent and a third vent via a connecting pipe that is incorporated into a wall of the piston;
• and
• a multi-directional valve controller, wherein the multi-directional valve controller is one of a mechanical or an electronic controller, wherein the multi-directional valve controller overlies the first vent and the second vent, and wherein the multi-directional valve controller regulates airflow through the first vent and the second vent by opening and closing a first valve and a second valve in all possible combinations;
• opening the first valve and closing the second valve and compressing the piston head compresses the air in the second section, and draws fresh air into the first section, wherein compressed air in the second section acts as a spring to force the piston head in the reverse direction, and wherein the force required to compress the piston head is conserved to assist in reverse movement of the piston head;
• opening the second valve and closing the first valve, whereby pressure above and below the piston head is continuously equilibrated by free flow of the air through the connecting pipe, wherein the piston head movement is free and unhindered without recoil assistance, and wherein previous pressure setting and the recoil assistance can be resumed on demand by closing the second valve and opening the first valve when the piston head is fully retracted;
• closing both the first valve and the second valve, whereby the piston head movement in both directions is retarded due to vacuum effect in the first section and positive air pressure in the second section;
• and
• opening both the first valve and the second valve, whereby the first section and the second section are both depressurized to ambient pressure, and the piston head movement is free with no recoil assistance.
