摘要： The injection system comprises a high-pressure pump (10) which is lubricated with the fuel and fed by a low-pressure pump (9) via a feed line (11). The high-pressure pump (10) comprises a pump body (26) inside which a pumping member (17) is arranged and has a chamber (27) inside which a mechanism (24) for actuating the pumping member (17), provided with a shaft (23), is arranged. The chamber (27) has an inlet opening (41) communicating with the feed line (11) so as to supply into the chamber (27) itself a part of the fuel fed by the low-pressure pump (9) in order to lubricate and cool the actuating mechanism (24). The chamber (27) also has an outlet opening (55) communicating with a line (38) for discharging the excess pumped fuel. A choke (56) is arranged, for example, in the outlet opening (55), said choke being designed to limit the quantity of fuel discharged from the chamber (27) into the discharge line (38). In particular, the low-pressure pump (9) is a mechanical actuating pump synchronized with the shaft (23) of the actuating mechanism (24) of the high-pressure pump (10) and is combined with this pump (10) so as to form a single pump unit (3).
