摘要: A valve device includes a body (4) in which a gas flow passage is provided; and a check valve (16) provided in the gas flow passage, the check valve (16) including a poppet (84) and a valve seat. The poppet (84) excluding a block portion (91) is in a form of a hollow shaft, the block portion (91) being located at a distal end of the poppet (84) and having a taper shape, and the poppet (84) has at least one side hole (95) that provides communication between an inside and an outside of a portion of the poppet (84), the portion being in the form of the hollow shaft. The at least one side hole (95) extends obliquely with respect to a central axis line of the poppet (84) such that the at least one side hole (95) extends along a gas flow direction inclined with respect to a direction in which the poppet (84) moves when the check valve (16) opens.

The poppet (84) excluding a block portion (91) is in a form of a hollow shaft, the block portion (91) being located at a distal end of the poppet (84) and having a taper shape, and the poppet (84) has at least one side hole (95) that provides communication between an inside and an outside of a portion of the poppet (84), the portion being in the form of the hollow shaft. The at least one side hole (95) extends obliquely with respect to a central axis line of the poppet (84) such that the at least one side hole (95) extends along a gas flow direction inclined with respect to a direction in which the poppet (84) moves when the check valve (16) opens.
