The invention relates to an air inlet valve device for an aircraft landing buffering airbag. The device comprises a valve body, and the valve body is of a hollow column structure. An air inlet, outerbag inflation openings and an inner bag inflation opening are formed in the valve body, and the air inlet is formed in one end of the valve body and communicates with the hollow structure of the valvebody. The outer bag inflation openings are two or more through holes distributed in the side face of the middle section of the valve body, and communicate with the hollow structure of the valve bodyto form an outer bag inflation air channel. The inner bag inflation opening is formed in the other end of the valve body and communicates with the hollow structure of the valve body to form an inner bag inflation air channel. Air entering the air inlet inflates an outer bag and an inner bag at the same time through the outer bag inflation air channel and the inner bag inflation air channel. According to the air inlet valve device, the inner bag and the outer bag of the combined buffering airbag can be inflated at the same time through air distribution, the inner bag and the outer bag share thesame inflation assembly, the complexity of an inflation pipeline can be reduced, and meanwhile the weight of the inflation assembly can be reduced.

    本发明涉及一种飞行器着陆缓冲气囊用进气阀装置,该装置包括阀体,阀体为中空柱体结构,阀体上设有进气口、外囊充气口和内囊充气口,进气口位于阀体一端端部,与阀体的中空结构联通;外囊充气口为分布在阀体中段侧面的两个或多个通孔,与阀体的中空结构联通,形成外囊充气气路;内囊充气口位于阀体另一端端部,与阀体的中空结构联通,形成内囊充气气路,从进气口进入的气体,通过外囊充气气路和内囊充气气路同时给外囊和内囊充气。本发明能够通过气体分流实现给组合式缓冲气囊的内、外囊同时充气,内外囊共用一套充气组件,可以减少充气管路的复杂性,同时可以减轻充气组件重量。
