摘要： 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.

摘要： A pressure reducing valve comprises an open-close valve and a piston. The open-close valve makes switching between connecting and isolating a primary port and a secondary port. The piston makes sliding motion inside the cylinder according to a difference between force applied from the pressure regulating chamber and force applied from the pressure reducing chamber, thereby opening and closing the open-close valve. The open-close valve includes a valve stem and a valve seat fixing member. The valve seat fixing member restrains displacement of the piston toward a side upstream of the open-close valve by abutting on an end surface of the piston. The valve seat fixing member includes a channel hole communicatively connecting a housing part for the valve stem and the pressure reducing chamber.
