<P>PROBLEM TO BE SOLVED: To provide a small and low-cost fluid control valve capable of generating a sealing force surely between a valve member and a valve seat when a valve is closed. <P>SOLUTION: An air pressure regulating valve 4 converts the rotation of a stepping motor into linear advancement motion to move a valve shaft 44 in an axial direction in a valve housing 41. A valve member 45 mounted on the valve shaft 44 moves with the valve shaft 44 to open and close the air pressure regulating valve 4 by being seated on or separated from a pressure regulating valve seat 411f. The valve member 45 has a valve frame 451, on which a seal member 452 is mounted. The mounting part 451d of the valve frame 451 is mounted to be capable of inclining to a support body 445 of the tip end of the valve shaft 44. A gap in the radial direction is formed between the inner circumferential surface of the cylindrical part 451c of the valve frame 451 and the outer circumferential surface of the valve shaft 44. The gap in the radial direction restricts the inclination of the valve member 45. <P>COPYRIGHT: (C)2013,JPO&INPIT |
