<P>PROBLEM TO BE SOLVED: To provide a technology of suppressing the instability of the operation of a valve body and improving closed valve responsiveness. <P>SOLUTION: A fuel supply valve 10 includes a body 12, a valve seat member 34, a valve body 40, and a throttling member 52. The valve body 40 is housed in the body 12 to be movable between a closed valve position to abut on the valve seat member 34 and an open valve position to be separated from the valve seat member 34. In a state where the valve body 40 is in the open valve position, a throttling part 20a connectes the upper side with the lower side. When the valve body 40 is in the opening position, the flow path area of the throttling part 20a is smaller than that when the valve body 40 is in the closed valve position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
