Abstract
An airgun pressure system as described herein includes a pressure chamber comprising a cylinder extending along a length of an axis of the airgun parallel with an axis of a barrel of the airgun. The airgun also includes a piston disposed within the pressure chamber and translatable along a length of the cylinder to pressurize gas in the pressure chamber in response to an increase in force applied to the piston. The airgun also includes a rotating drum connected to a frame of the airgun, a cable operably connected to the piston and the rotating drum, and a crank handle operably connected to the rotating drum and configured to cause rotation of the rotating drum to increase tension on the cable and force on the piston to compress the gas in the pressure chamber.
