Title:
FUEL INJECTION PUMP AND METHOD OF ADJUSTING THE SAME PUMP
Document Type and Number:
WIPO Patent Application WO/1985/005152
Kind Code:
A1
Abstract:
A fuel injection pump has plunges (8) operated by a cam (12) in front of a pressure chamber (20), control sleeves (14) engaging the plungers (8) in a fuel chamber (15), and an oblique slot (8d), a longitudinal slot (8c) provided at one of the plungers (8) or the sleeves (14) for controlling the communication between the chamber (20) and the chamber (15) through an oil passage (8a) in the plunger (8) and a control hole (14a) cooperating with both the slots (8c, 8d) formed at the other of the plungers (8) or the sleeves (14). The effective stroke of the plunger (8) is controlled by varying the relative position between the slots (8d) and (8c) and the hole (14a) by rotating the plunger (8) around the axial line, and the pre-stroke; hence, fuel injection timing is readily controlled merely by moving the sleeve (14) in the plunger axial direction, thereby eliminating the need for a centrifugal timer.
