Abstract: A pump unit for feeding fuel, preferably diesel fuel, to an internal combustion engine; the pump unit (1) comprising: a head (4) inside which a cylinder (12) extending along an axis (A1) is formed; a pumping piston (5) extending along the axis (A1) and slidingly coupled with the cylinder (12); a through-hole (13) which extends from the cylinder (12) towards the outside of the pump unit (1); an intake chamber (8) communicating with the cylinder (12) via the hole (13); an intake valve (7) which controls the flow of fuel from the intake chamber (8) to the hole (13); a cap (23; 123; 223) which is connected to the head (4), is arranged on the opposite side to the pumping piston (5) and can be selectively fixed along an outer surface (25) of the head (4) so as to close the intake chamber (8) on one side.

Abstract: A pumping assembly for feeding fuel, preferably diesel fuel, to an internal combustion engine, has a pump body (4, 9), at least one cylinder (14) formed in the pump body (4, 9), a closing lid (29) defining, together with the pump body (4, 9), an intake chamber (39) for drawing the fuel into the cylinder (14), an annular tooth (32) projecting from the closing lid (29) and an annular recess (35) formed in the pump body (4, 9) for receiving and housing the annular tooth (32) so as to couple the pump body (4, 9) and the closing lid (29) together in a fluid-tight manner.
