Abstract:
A welded high-pressure fuel pump roller tappet, which is used for the fuel injection system in an engine, includes a guide sleeve, a U-shaped holder and a pin-shaft-roller set. Symmetrical positions on the upper portion of left and right sidewalls of the guide sleeve are provided with inflexed flanges. Two sides of the flange are folded inwardly to form a limiting slot. The U-shaped holder includes a bottom plate and side plates located on left and right sides of the bottom plate. Symmetrical positions on two side plates are provided with axle holes. The pin-shaft-roller set is set up between two side plates of the U-shaped holder. Symmetrical positions on the upper portion of the flange are provided with opening slots. After assembly, the U-shaped holder is located between two flanges. Two side plates are located inside the limiting slots in the flanges.
