ABSTRACT:
A gas inlet valve assembly for inflatable boats includes valve structure having at least one inlet opening and at least one outlet opening. A valve member is positionable between the inlet opening and the outlet opening to control the flow of gas through the valve. A gas dispersion member, preferably made of a porous material, is provided with the valve and is substantially adjacent to the valve outlet opening, such that gas emanating from the valve outlet opening will be thrust into contact with the gas dispersion member. The expanding, cold gas jet is dispersed by the porous material of the gas dispersion member. Direct contact between the cold gas jet and raft surfaces, together with freezing and cracking associated therewith, will thereby be substantially prevented. In a preferred embodiment, a pluraity of radially-disposed outlet valve openings are provided, and the gas dispersion member is substantially annular. The valve outlet openings are disposed substantially adjacent to the open interior of the annular gas dispersion member, such that the cold gas jets emanating from the valve outlet openings will be thrust into contact with the interior annular surface of the gas dispersion member.
