PURPOSE:To prevent the reduction of fuel pressure due to the rise of fuel temperature and the generation of vapor due to the rise of fuel temperature and the reduction of fuel pressure by varying a gap between a movable valve and a holding member according to the change in fuel temperature. CONSTITUTION:Fuel not supplied to a fuel injection valve 4 is supplied to a fuel pressure controlling valve 8 which maintains the pressure of fuel supplied to the fuel injection valve 4 at a predetermined pressure condition. A holding plate 820 sandwiching a ball 818 is constituted from a bimetal so that a gap between ends 822 sandwiching the ball 818 is enlarged by the rise of fuel temperature and accordingly the ball 818 is displaced in the direction of separating from the holding member 817 to enlarge a gap between a movable valve 816 and the holding member 817. |
