Abstract (en)
[origin: WO2012136429A1] A pump unit for supplying a fuel, preferably diesel oil, to an internal combustion engine (3) is provided with a pre-feed pump (7) adapted to draw the fuel from a containing tank (2), and with a fluid circuit (14) having a first branch (15) for interconnecting the pre-feed pump (7) and a high-pressure pump (6), a second branch (17) for interconnecting the high-pressure pump (6) and the internal combustion engine (3), and a third branch (21), which interconnects the first branch (15) and the containing tank (2), and is formed at least partially by an overflow valve (26) and by a connector (37) mounted coaxially with each other in a mounting aperture (27) formed through a pump housing (8) of the high-pressure pump (6).
