ABSTRACT:
Air gun apparatus for firing missiles 11 including a gun and a replaceable cartridge assembly. The cartridge assembly includes a casing having a detachable hollow nose, a pressure cylinder slidably located in the casing, and a valve mechanism normally biased by a valve spring in the cylinder to close a gas discharge path from the interior of the cylinder to the hollow nose via a removable hollow valve abutment member. The valve mechanism is openable by forcible movement of the cylinder towards the hollow nose. The gun includes a seating at a breech end of a barrel, a breech, and a breech block assembly. A firing spring acts on an inertia member which is releasable by a trigger mechanism. The breech block assembly includes a thrust member biased in a direction toward the seating by a centering thrust spring for thrusting the cylinder 13 toward the barrel so as to take up clearances with the valve mechanism and to thrust the hollow nose against the seating when the breech block assembly is moved into a firing position. The cartridge is rechargable with compressed air by a pump having a reload mechanism to engage and support the cartridge after removal of the nose and abutment member.
