摘要： A new air cushion support system for air cushion vehicles is composed of a plurality of annular peripheral jet units or modules distributed in an array in a common plane. Each peripheral jet module develops a separate air cushion or air bubble under the module to provide a plurality of independent air cushions under a vehicle. Each peripheral jet module or unit is a spring-loaded pressurized air valve with a control piston at the center of the valve spring biased to respond to back pressure variation of the air bubble or air cushion developed beneath the module caused by variations in terrain over which a vehicle is traveling. Each module or valve is formed by a pod defined by an inwardly sloping peripheral outer wall or pod skirt for directing pressurized air inwardly and downwardly toward the pod. Each module further includes a valve head, piston or pit seating within the pod skirt. The pit is formed with an inwardly sloping outer peripheral wall seated within the pod with the pit wall spaced from the pod skirt. The pod skirt and pit wall define the annular peripheral air jet channel of the module for developing a pressurized air bubble or air cushion. Each pit is movably mounted and spring loaded relative to the pod for independent motion of the pit vertically up and down within the pod for varying volume rate of flow of air expelled in the air curtain in response to variations in back pressure under the module during travel over varying terrain.
