Abstract
A pressure sensitive member (68) is operatively connected to a pressure regulator assembly (80, 100) through a cam section (64b) of a control pin (64) and a follower pin (76). The pressure regulator assembly (80, 100) regulates a fuel pressure inside a chamber (12a) of a pump housing (12) upon a change of a pressure acting on the pressure sensitive member (68), thereby compensating a timing of fuel injection determined by an injection timing control member (24). The pressure acting on the pressure sensitive member (68) is an atmospheric pressure or a boost pressure. The pressure regulator (80, 100) is adjustable to either advance or retard the injection timing as desired in conformity with an atmospheric pressure or a boost pressure, or to vary the point at which the fuel pressure in the pump chamber (12a) starts to be varied.
