Abstract
PURPOSE: To change a fuel injection quantity per unit valve-opening time of a fuel injection valve in accordance with a manifold negative pressure so as to obtain a proper air-fuel ratio, by changing a difference between a fuel pressure and the manifold negative pressure in accordance with manifold negative pressure.
CONSTITUTION: Diaphragms d2 and d3, and pillar-shaped member 32 is shifted upward when a manifold negative pressure Pm is decreased, while shifted downward when the Pm is increased. In accordance with this up-down motion, a diaphragm d1 and a valve body 52 are shifted up- and downward, and the valve body 52 increases and decreases quantity of a pressurized fuel which is turned back to a fuel tank from a decompression chamber A through an oil sending tube 50 so as to control a pressure supplied to a fuel injection valve from the decompression chamber A. The upper end portion of a coil spring 38 is shifted downward or upward together with the upper diaphragm d2 in accordance with increase or decrease of the Pm.
