Abstract
Disclosed is a gas fired gun having a valve body for communicating gas under pressure from a gas cartridge to the gun barrel to fire a projectile. The gun has a frame carrying a chamber for receiving a gas cartridge and a lever for urging the cartridge in the chamber against a conical element carried in a stepped bore in the valve body. A retainer ring having triangular shaped projections disposed in a direction toward the tip of the conical element is provided about the element. A seal seats on a stepped shoulder in the bore and a retainer nut bears against the seal which, in turn, bears against the triangular projections on the ring to retain the conical element in the bore. Upon actuation of the lever, the end of the cartridge is fully inserted into the bore and pierced by the element. When the lever is in final position, the cartridge backs off the piercing element to enable gas flow through the seal between the projections of the retainer ring and the element into the valve body passage.
