The pump comprises a plurality of cylinders (4) disposed radially in a star formation around a shaft (5) with an eccentric (6) in a body (2, 3) formed by first and second members (2, 3) joined together by bolts (13). Each cylinder (4) is clamped in position between the first and second elements (2, 3) of the body between a pair of the said bolts (13). The facing surfaces of each cylinder (4) and of at least one (3) of the members (2, 3) of the pump body are spaced in correspondence with the central portion of the cylinder (4) in which is formed the chamber (9) in which the associated piston (10) is movable, so that the contact between the cylinder (4) and the at least one member (3) of the body (2, 3) of the pump is limited to surfaces outside the central portion of the cylinder (4).

An electromagnetically-controlled fuel injection valve for diesel engines includes a body having an upper electromagnetic metering valve which controls communication between a control chamber supplied with the pressurized fuel and a discharge port. The metering solenoid valve, which itself constitutes a unit independent of the rest of the injection valve, is supported by a head element connected to the body of the injection valve by axial clamping means and has an appendage which carries the control chamber and the discharge port and is inserted in an axial seat in the body with the interposition of double sealing means.
