Puissance hydraulique et depot de sediments en eaux courantes

In a lifter guide of a high pressure supply pump, a flat plate, whose periphery line is provided with a projection and whose the other periphery line circumferentially opposed to the periphery line is provided with a recess, is formed from a metal sheet by stamping. Then, the flat plate is rounded circumferentially so as to cause the periphery line to abut on the other periphery line so that the flat plate is formed in generally cylindrical shape and the projection is fitted to the recess. Subsequently, the periphery line is seamed by staking or welding with the other periphery line to reinforce fitting between the projection and the recess. Thinner wall thickness of the lifter guide can be achieved with a simpler process, compared to that of the conventional lifter guide formed by forging or machining.
