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.

[ It is claimed:] [1.]1. An inflation valve selectively sealable to a pressurized tank, the valve comprising:a one-piece valve body having a gas passage therein, the gas passage extending from a first opening selectively attachable to the pressurized tank to a second opening;a replaceable cartridge insertable via the second opening within the gas passage for blocking the gas passage while still allowing for filling of the pressurized tank from a fill port to the first opening, the cartridge including a bayonet guiding bore receiving a punctures disc for preventing the transmission of gas through the gas passage absent the breaking. of the puncture disc;a bayonet biased toward the puncture disc and movable within the bore in the gas passage for selectively puncturing the puncture disc; anda detent for blocking the bayonet bias and detaining the bayonet from puncturing the puncture disc.
