Abstract
An injection timing control system for a fuel-injection pump for an engine has a phase angle regulator for varying the rotational phase angle of a drive shaft of the fuel-injection pump. The regulator has a cylindrical extension of one of an input shaft adapted to be driven by the engine and an output shafts for driving the drive shaft of the pump coaxially surrounding an end portion of the other shaft in spaced apart relationship. A male spline and female spline are formed respectively on the end portion and the extension over some axial length thereof, at least one of the splines being a helical spline. A slider is located in an annular space between the splines and formed with splines meshing therewith respectively. An annular cylinder is formed between the substantial parts of the rest axial length portions of the cylindrical extension and end portion. A piston is reciprocally received in the cylinder, the slider and piston being formed as a unit.
