ABSTRACT:
A gun can be powered by a cartridge of pressurized gas or by pressurized air. The gun includes a valve body which provides a pressure reservoir for storing pressurized gas or air. When the gun is fired, pressurized gas or air is discharged from the pressure reservoir and propels a projectile out of the barrel of the gun. An air pump is mounted on the gun for supplying pressurized air to the pressure reservoir. An adapter assembly is mounted on the gun for holding a cartridge of compressed gas. The adapter assembly includes an adapter housing and a plunger which is slidably mounted in the adapter housing. The plunger is movable between a sealing position in which the plunger sealingly engages the adapter housing and an exhaust position in which pressurized gas or air from the pressure reservoir can flow out of the adapter housing. The plunger is maintained in the sealing position by a gas cartridge or by a plug which can be screwed into the adapter housing. A check valve in the plunger permits pressurized gas to flow through the plunger into the pressure reservoir but prevents pressurized gas or air to flow from the pressure reservoir through the plunger.
