Abstract (en)
[origin: JPS6445959A] PURPOSE: To make it possible to actuate free from abrasion by elaborating an engagement method of a rider with a control sleeve relating to a device in which a fuel injection onset is adjusted by axially displacing the control sleeve outwardly fitted to the pump plunger, by way of rider. CONSTITUTION: A fuel injection pump has a plunger 3 reciprocated by the rotation of a cam axis through a tappet and by this reciprocation, the fuel sucked within a work chamber 18 is pressurized and discharged into the pressure passage 19. Furthermore, the injection time of fuel is adjusted due to the fact that a control sleeve 9 fitted outwardly to the plunger 3, is axially moved and by the same token, the amount of fuel injection is adjusted by a control rack 29 by moving the plunger 3 to pivot. In this instance, the head 44 of an adjusting pin 14 is formed to be equipped with two plane sections 55 and in the end surface 46 of a slide shoe 43, a facing projection 57 by way of a gap 58, is formed in between the plane sections 55.
