Document Type and Number:
Japanese Patent JP6736411
Kind Code:
B2
Abstract:
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
