Abstract
Official abstract text for this publication.
A valve device includes a body in which a gas flow passage is provided; and a check valve provided in the gas flow passage, the check valve including a poppet and a valve seat. The poppet excluding a block portion is in a form of a hollow shaft, the block portion being located at a distal end of the poppet and having a taper shape, and the poppet has at least one side hole that provides communication between an inside and an outside of a portion of the poppet, the portion being in the form of the hollow shaft. The at least one side hole extends obliquely with respect to a central axis line of the poppet such that the at least one side hole extends along a gas flow direction inclined with respect to a direction in which the poppet moves when the check valve opens.
First claim
Opening claim text (preview).
What is claimed is: 1 . A valve device configured to be fitted to a gas tank in which high-pressure gas is stored, the valve device comprising: a body in which a gas flow passage is provided, the gas flow passage providing communication between an inside and an outside of the gas tank; and a check valve provided in the gas flow passage, the check valve including a poppet that suppresses discharge of the gas inside the gas tank to an outside of the body, and a valve seat with which the poppet makes contact and from which the poppet separates, wherein: the poppet excluding a block portion is in a form of a hollow shaft, the block portion being located at a distal end of the poppet and having a taper shape, and the poppet has at least one side hole that provides communication between an inside and an outside of a portion of the poppet, the portion being in the form of the hollow shaft; and the at least one side hole extends obliquely with respect to a central axis line of the poppet such that the at least one side hole extends along a gas flow direction inclined with respect to a direction in which the poppet moves when the check valve opens. 2 . The valve device according to claim 1 , wherein an intersection angle of a central axis line of each of the at least one side hole with respect to the central axis line of the poppet is equal to or larger than 20° and equal to or smaller than 60°. 3 . The valve device according to claim 1 , further comprising: a joint connecting a pipe to the gas flow passage; and a positioning member having a communication hole that communicates with the gas flow passage, wherein: an outer surface of the body has a fitting hole that leads to the gas flow passage; in the fitting hole, the joint and the positioning member are arranged in a stated order from an outer side of the body; and the positioning member is configured such that the positioning member is able to set a position of the valve seat even in a state where the joint is not fitted to the fitting hole. 4 . The valve device according to claim 3 , wherein: the gas flow passage includes an increased diameter portion in which the valve seat is fitted, and a valve accommodation portion in which the poppet is accommodated; an inside diameter of the valve accommodation portion is smaller than an inside diameter of the increased diameter portion; and the positioning member sets the position of the valve seat by pressing the valve seat to a connecting surface that connects an inner peripheral surface of the increased diameter portion and an inner peripheral surface of the valve accommodation portion.
