Abstract

PURPOSE:To permit the fuel injection rate to be varied continuously by installing the position controlling means for positioning a movable plunger barrel in reciprocative movement, in series-type injection pumps or monocylinder type one. CONSTITUTION:When a plunger 4 lowers and the hole 16 on a plunger barrel 3 is opened, suction of fuel starts, and terminates at the lowest position. Then, a cam shaft turns and the plunger 4 rises and the hole 16 is closed, then the fuel pressure increases, and a delivery valve 27 is opened to feed fuel under pressure, and a notched part 17 coincides with the hole 16, then supply of fuel is completed. As the notched part 17 is formed obliquely, if the second control rack 23 is position-controlled by a solenoid etc., and the relative revolution position between the plunger 4 and the barrel 3 is controlled, then the effective stroke is varied, and the amount of injection can be controlled. Further, the barrel 3 can be shifted in the direction of shaft line by position-controlling the first control rack 15, and the relative relation between and the position of coincidence of the notched part 17 with the hole 16 the cam phase thus the injection rate can be controlled arbitrarily.
