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.
