PROBLEM TO BE SOLVED: To provide a suction type operating valve enabling a sick bedridden person to freely drink in a bedridden state.SOLUTION: A suction type operating valve using breath enables a bedridden person to freely drink a beverage supplied from a container through a tube by a siphon effect or a gravity drop. The suction type operation valve is structured such that a swing valve opened to an inflow side is used for a main valve body 14, a breathing branch path 35 is disposed behind the main valve body 14, at the branch path 35, a swing type breathing valve body 40 is disposed to open to the outside of the flow path, and the main valve body 14 and the breathing valve body 40 are connected to each other by a connection stick so as to close one while opening the other. When the breathing valve body 40 is set larger than the main valve body 14, and the flowout side is sucked, the breathing valve body 40 receives a stronger suction force than the main valve body 14, the main valve body 14 is opened while the breathing valve body 40 is closed, and thus the beverage can be sucked.COPYRIGHT: (C)2014,JPO&INPIT【課題】寝たきり状態の病人が寝たままで自由に飲み物を飲むことができる吸引式作動弁。【解決手段】容器から管によりサイフォン効果や重力落下で供給した飲料を寝たままの人が自由に飲むことができる、息を利用した吸引式作動弁。構造は主弁弁体14に流入側に開くスイング式の弁を用いて、主弁弁体14の後ろに呼吸分岐路35を設け、ここに流路外側に開くスイング式の呼吸弁弁体40を設け、主弁弁体14と呼吸弁弁体40を片方閉じて片方開くように連杆で連結する。呼吸弁弁体40を主弁弁体14より大きくすることで、流出側を吸引すると、呼吸弁弁体40が主弁弁体14より強い吸引力を受け、呼吸弁弁体40が閉じる一方主弁弁体14が開いて、飲料を吸引することができる。【選択図】図1
