The pump (5) has a hollow body (7) in turn having a group of radial cylinders (6) in which slide respective pistons (16) activated by a common cam (11) rotating inside the hollow body (7). The hollow body (7) is closed by a cover flange (8) carrying a series of fuel supply conduits (10). The hollow body (7) is made of high-tensile steel and integrally carries the cylinders (6), each of which is formed in a radial appendix (18) forming, with an inner surface (19) of the hollow body (7), an annular chamber (20) housing a compression spring (21) for recalling the respective piston (16). |
