Abstract
PURPOSE: To set optimal fuel injection timing in accordance with each of various running conditions, by installing a control valve in an oil pressure transmission unit which communicates with a pressure chamber on a piston for controlling the fuel injection time and by regulating the control valve depending on the running condition.
CONSTITUTION: When a drive shaft 1 is moved by an engine, fuel pressurezied by a feed pump 3 is discharged into a pump chamber 2 and supplied under pressure to cylinders through the fuel passage 8 of a plunger 6, which is caused to slide by a cam plate 5, and through a chamber 27, fuel passages 9, 10, a discharge port 14 and a delivery valve 18. The cam plate 5 is coupled to a hydraulic piston 24 through a shaft 22. The hydralic piston 24 is held in position where the forces of an oil pressure chamber 25 and a spring 26 are balanced to each other. As a result, fuel injection timing based on the plunger 6 is controlled. Oil pressure applied to the oil pressure chamber 25 is adjusted by a control valve 56 which is regualted depending on a revolution speed and a load detection mechanisms 60, 61.
