Abstract
A prestroke adjustment mechanism for a fuel injection pump comprises a U-shaped lever provided on the outer surface of the pump housing for rotating a timing control rod of the injection pump and a rotation limit pin provided on the same outer surface for limiting the rotation of the U-shaped lever. The timing control rod is linked with a control sleeve on the pump plunger for adjusting the prestroke. By limiting the rotation of the U-shaped lever, the rotation limiting pin limits the height of the control sleeve for ensuring establishment between the top of the control sleeve and the bottom of the upper section of the plunger barrel of a gap for dissipating the force of the spill jet during fuel spill. As a result, the downward force of internal turbulence produced by the spill jet is dissipated, thereby preventing the control sleeve from slipping downward and ensuring stable and reliable prestroke adjustment.
