RAFT INFLATION VALVE ABSTRACT OF THE DISCLOSURE A raft inflation valve includes a valve body having an inlet, an outlet, an internal cylinder open at one end to the valve outlet, and an inlet passage leading from the valve inlet to and intersecting with the midsection of the internal cylinder. A double-ended balanced piston with O-ring seals on both ends is positioned in the internal cylinder so that one end blocks the passage to the outlet. In this position (valve closed) the O-ring seals are on opposite sides of the intersection of the inlet passage which results in a balancing of the gas pressure forces acting on the piston. When the valve is actuated, a firing mechanism causes the piston to move away from the outlet end of the internal cylinder so that the piston head partially uncovers the outlet passage. Once the outlet passage is partially uncovered, the gas pressure forces on the piston become unbalanced and the pressure rapidly accelerates the movement of the piston the remaining distance out of the passage, which then allows the inflation gas to flow freely through the valve to the raft.
