ABSTRACT:
A fuel injection pump including an improved plunger pre-stroke adjusting mechanism which comprises a control sleeve coupled with a control rod through a coupling shaft. The coupling shaft is rotatably mounted in an aperture defined in the control rod and has an engagement portion held in engagement with the control sleeve. The engagement portion is disposed in eccentric relation to a body of the coupling shaft for translating rotating motion of the control rod into axial movement of the control sleeve, thereby adjusting the pre-stroke of a plunger. The pre-stroke adjusting mechanism thus constructed is compact and simple in construction and hence can easily be assembled.
