<P>PROBLEM TO BE SOLVED: To provide a flow control valve driveable without equipping an electromagnetic driving means. <P>SOLUTION: The flow control valve (40) includes a cylinder (50) formed with a fuel supply opening (53) supplied with fuel delivered from a feed pump (20) in a side wall and a fuel discharge opening (54) discharging fuel supplied from the fuel supply opening, a valve element (60) disposed in the cylinder such that a first chamber (51) is formed in a space with one end in the cylinder and a second chamber (52) is formed in a space with another end in the cylinder, and slid in the cylinder by a difference of force received from the first chamber and force received from the second chamber to adjust opening rates of the fuel supply opening and the fuel discharge opening, and a spring (70) disposed in the second chamber and energizing the valve element. A first opening (55) receiving inflow of one part of the fuel delivered from the feed pump is formed in the first chamber, and a second opening (56) receiving inflow of fuel of an atmospheric pressure is formed in the second chamber. <P>COPYRIGHT: (C)2010,JPO&INPIT |
