PROBLEM TO BE SOLVED: To provide a valve device in an simple structure, which can optimize its layout. SOLUTION: The valve device includes: a valve seat 11d in which an induction supply passage contacts the outside, and a vessel side passage contacts the inside, and which has a shaft in an opening direction of an opening 2a; a valve body 20 which can move in an axial direction to block a flow of fuel by being pressed and contacted on the valve seat 11d; a coil spring 30 which urges the valve body 20 against the valve seat 11d; a pressure receiving chamber Q formed by being bored in the axial direction of the valve body 20; a pin 60 which can move in the axial direction, one end of which can abut on a wall of the valve body 20; a plunger 53 with which the other end of the pin 60 is connected so as to move in the axial direction; and an electromagnetic coil 54 which moves the plunger 53 in a direction of the pressure receiving chamber Q. The inside diameter of the pressure receiving chamber Q orthogonal to the axis of the valve seat 11d is formed larger than the cut-off diameter of the valve seat 11d. COPYRIGHT: (C)2011,JPO&INPIT |
