VIBRATION DETECTION VALVE AND DAMPER WITH VIBRATION DETECTION VALVE
PROBLEM TO BE SOLVED: To provide a vibration detection valve not requiring any electric power and capable of being opened or closed in a superior manner only through inputting vibration by a simple configuration.SOLUTION: A vibration detection valve 60 comprises a housing 61, a first moving body 70, and a resilient body 90. The housing 61 is formed with an inner space S, a flow-in port 64 and a flow-out port 68. The inner space S has a receiving surface 66. The flow-out port 68 is communicated with a flow-out outlet 67 opened at the central part of the receiving surface 66. The first moving body 70 is movably stored in the inner space S so as to open or close the flow-out outlet 67. The first moving body 70 oppositely faces against the receiving surface 66 and has a first surface 71 that is bulged out into a curved surface shape to be gradually spaced apart from the receiving surface 66 at a vertical section toward an outer edge part when its central part is positioned under a valve closed state in which it closes the flow-out outlet 67. The resilient body 90 applies an elastic force in such a direction as one in which the first moving body 70 is pushed against the receiving surface 66.SELECTED DRAWING: Figure 3
【課題】電力を必要とせず、簡易な構成で振動の入力だけで良好に開閉することができる振動検知バルブを提供する。【解決手段】振動検知バルブ６０は、ハウジング６１、第１移動体７０、及び弾性体９０を備えている。ハウジング６１は、内部空間Ｓ、流入ポート６４、及び流出ポート６８が形成されている。内部空間Ｓは受け面６６を有している。流出ポート６８は受け面６６の中央部に開口した流出口６７に連通している。第１移動体７０は流出口６７を開閉するように内部空間Ｓ内に移動自在に収納されている。第１移動体７０は、受け面６６に対向し、中央部が流出口６７を閉じた閉弁状態に位置した際に、鉛直断面において、中央部から外縁部に向けて徐々に受け面６６から離れるように湾曲面形状に膨らんだ第１面７１を有している。弾性体９０は第１移動体７０を受け面６６に押さえつける方向に弾性力を付与している。【選択図】図３
