Abstract
A raft inflation valve includes a one-piece valve body which is connected to a pressure vessel and which has an inlet communicating with the pressure vessel, a recess for receiving a cartridge having a puncture disc, and a passage which connects the inlet and the recess and which is covered by the puncture disc. The cartridge includes a disc retainer holding the puncture disc in position to block the passage in the valve body, and a bayonet having a cuffing edge which is biased by a spring toward the puncture disc but prohibited from such motion by a ball/link pin held in place by the pull cable ball until the cable is pulled. Once the cable has been pulled to remove the ball, the bayonet is driven by the bias force toward the disc to clearly cut and puncture the disc and permit flow of gas from the pressure vessel through the inlet passage through the disc to the outlet passage in the outlet of the valve.
