PROBLEM TO BE SOLVED: To provide a flow control device capable of hastening the formation of an oil film in a sliding part, securing the smooth movement of a valve member, and improving flow adjusting accuracy. SOLUTION: The valve member 30 is housed in a valve body 21 at the inner peripheral side thereof. The valve member 30 has a guide part 33 sliding with the inner wall surface 25 of the valve body 21. The inner wall surface 25 of the valve body 21 and the guide part 33 of the valve member 30 form a sliding part. The guide part 33 is formed with a groove 34 continued in the circumferential direction at peripheries of two positions in the axial direction. The groove 34 holds lubricating fuel. The fuel in the groove 34 is supplied to the sliding part, and the sliding part is formed with an oil film of the fuel. As a result, sliding resistance in the sliding part is reduced, and the valve member 30 can smoothly move. Flow adjusting accuracy by the movement of the valve member 30 can be thereby improved. |
