Abstract:

A fuel injection pump, comprising a cam shaft (7) driving a plunger (4) and a feed pump (3) assembled therein for feeding fuel pressured by the plunger (4), wherein a flange part (52) projecting radially is provided on the cam shaft (7), an internal gear (41) transmitting a power to the feed pump (3) is provided at the end part of the cam shaft (7) on the side opposite to the end part of the driven side of the cam shaft (7), and a housing member (8c) rotatably supporting the cam shaft (7) through a radial bearing (12) is held between the flange part (52) and the internal gear (41) so as to adjust the axial position of the cam shaft (7), and then a function to adjust the axial position of the cam shaft is substituted for the existing member assembled into the pump, whereby an axial gap due to a deterioration of durability of the bearing is eliminated to be adjusted so as to facilitate the assembly, reduce the number of parts, and reduce the size of the injection pump.
