ABSTRACT:
A fuel pump set includes a cam shaft with a cam; a bridge contacting the cam shaft; a head cover attaching the bridge to the cam shaft; and a fuel pump, disposed in the bridge and operable by the cam. The bridge may include two supports, each contacting the cam shaft. One support may have a supporting face, with a shape corresponding to the shape of the cam shaft, with the cam shaft disposed therein. The two supports together may define a shape that widens downward. One support may narrow downward. The set may also include a rod extending from the fuel pump to the cam, reciprocated by the cam. The bridge may include a sealing face supported by the head cover, a groove for preventing rotation of the fuel pump, and/or a breather. The head cover may include an opening in which the fuel pump is disposed.
