<p><P>PROBLEM TO BE SOLVED: To provide a fuel injection pump superior in abrasion resistance and seizure resistance. <P>SOLUTION: The fuel injection pump 10 has a camshaft 20, a cam 21, shaft storage parts 141 and 142, bushes 191 and 192, a plunger 24 and cylinders 12a and 13a. The camshaft 20 is driven by an engine. The cam 21 is eccentrically arranged on the camshaft 20. The shaft storage parts 141 and 142 store the camshaft 20 at both sides in the axial direction of the cam 21. The cylinders 12a and 13a reciprocally support the plunger 24, and form a fuel pressurizing chamber 40 for pressurizing fuel by he plunger 24. The bushes 191 and 192 have bearing pressure resistant parts 171 formed at an end at the cam 21 side in the axial direction, and a seizure resistant part 173 formed at the opposite side of the cam 21 with respect to the bearing pressure resistant part 171. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
