Abstract: A high pressure air cylinder-nozzle assembly includes a cylinder frame body, a piston assembly including a piston base member and a nozzle, the piston base member being configured to move along an axis in the cylinder frame body relative to the nozzle in at least one stage of multi-stage piston assembly movements between forward and back positions, and simultaneously with the nozzle in at least another stage of the multi-stage piston assembly movements, and a solenoid valve to direct air to the piston base member to move the piston base member between the forward and back positions.

Abstract: A high pressure air cylinder to use in an airsoft gun or similar devices and systems. In some embodiments, the present general inventive concept encompasses a cylinder in which an imbalanced poppet valve directs and controls the axial motion of a piston. Some embodiments include a two-way solenoid valve. Some embodiments include a precisely sit two-way solenoid valve. The solenoid valve controls the flow of air to drive a piston forward; air then pushes the piston back into place.
