  "abstract": "A system and a method for piston recoil pressure adjustment are disclosed. The system and the method use air compression in a piston to augment reverse motion. The system and the method contain a piston and a multi-directional valve controller. The multi-directional valve controller allows the venting of air in a first section above the piston head externally and/or to a second section below the piston head. By alternatingly opening and closing the vents, air can be pumped into the second section to increase the recoil forces. A reservoir connected to the second section below the piston head through an air retardation device serves to dampen abrupt changes of pressure during piston compression or decompression, thereby providing a relatively uniform recoil assistance.",
