To achieve this object, an air gun is constructed by a hit pin arranged in a cylinder portion, a valve body arranged within a hollow portion of the cylinder portion and having a bullet supplying nozzle chamber and a valve pin chamber, a gas inlet port opened to a sleeve-shaped circumferential face of the valve pin chamber, a bullet supplying nozzle arranged within the bullet supplying nozzle chamber, and a valve pin arranged within the valve pin chamber. The hit pin is pressed on a muzzle side and the valve pin is slid to the muzzle side so that an airtight state between a valve pin flange portion and a side face of the valve pin chamber on its gun rear end side is released. A compressed gas is supplied to a nozzle chamber side opening and a valve pin chamber side opening from a clearance between the valve pin flange portion and the gun rear end side face of the valve pin chamber. | InventorsAssigneeApplicationNo. 160805 filed on 09/25/1998US Classes:124/74, For discharge of pressure from removably mounted cartridge124/73, By valve means124/82Means for feeding projectile or ejecting cartridgeField of Search124/56, FLUID PRESSURE124/71, With control for discharge of fluid pressure124/73, By valve means124/74, For discharge of pressure from removably mounted cartridge124/76, Opened by spring-actuated means124/77, Opened by electrically actuated means124/81, Means for producing projectile spin or deflection124/82Means for feeding projectile or ejecting cartridgeExaminersPrimary: Carone, Michael J.Assistant: Bergin, James S.
