    • PROBLEM TO BE SOLVED: To provide a valve device reducing a mounting space and improving ease of attachment. SOLUTION: The valve device 2 is installed on a gas tank 1 capable of storing high-pressure hydrogen gas, and opens and closes the filling passage 3 of the hydrogen gas. The valve device 2 includes a housing 10 with a housing section 4 provided inside, a first check valve 21 and a valve pressing member 30, which are mounted to the housing 10 and form a through-hole bringing the housing section 4 and the filling passage 3 into communicate with each other. The housing 10 is formed with a filling port 11 bringing the outside and the housing section 4 into communicate with each other. The housing section 4 receives a filter 17 arranged between the filling port 11 of the housing 10 and a through-hole 22a of a passage member 20, and a ball valve 19 movable between the filter 17 and the filling port 11 by a flow of the hydrogen gas. When the hydrogen gas in the gas tank 1 flows into the housing section 4, the ball valve 19 moved to a filling port 11 side seats on a valve seat 13 and closes the filling port 11.

    • PROBLEM TO BE SOLVED: To provide a pressure regulator constituted so as to secure an excellent pressure regulating function by preventing the pressure regulating function from being affected by the connecting operation of a connecting tool by the pressure regulator comprising a pressure regulating mechanism and a connector and to stop the reverse flow of fluid caused by attaching/detaching operations of the connecting tool. SOLUTION: The pressure regulator comprises the connector 2 to which a supply connecting tool 3 supplying a pressurized fluid to a main body part 11 incorporating the pressure regulating mechanism 5 is connected. The connector 2 comprises a link member 544 openably operating a valve mechanism 6 according to the connecting operation of the supply connecting tool 3. The pressure regulating mechanism 5 comprises a pressure regulating valve 55 operated according to the deviation of a diaphragm 52 to regulate the pressurized fluid to a secondary pressure. The link member 544 is formed separately from the pressure regulating valve 55. Two check valves 56 and 57 for stopping the reverse flow of fluid are provided to the inside and outside of the pressure regulating valve 55. COPYRIGHT: (C)2006,JPO&NCIPI
