Fuel injection device

A fuel injection device (100) for a compression-ignition engine, the fuel injection device comprising a first storage unit (20) configured to be supplied with fuel by at least one high-pressure pump (16), the first storage unit (20) being arranged inside the high pressure pump (16), a first connecting line (26) from the first storage unit (20) to a second storage unit (30), and a second connecting line (40) from the second storage unit (30) to a fuel injector (50), wherein a third storage unit (42) is arranged inside a housing (52) of the fuel injector (50), which third storage unit is arranged separately from a high pressure chamber (44), in which an injection element (46) is arranged in a manner so as to be moved by lifting, and wherein a storage volume of the third storage unit (42) is a volume, corresponding to a plurality of nominal injection amounts of the fuel injector (50),

• wherein a first throttle device (36) restricting a flow rate is arranged between the first storage unit (20) and the second storage unit (30), and a second throttle device (38) restricting a flow rate is arranged between the second storage unit (30) and the third storage unit (42), and
• wherein a flow restrictor (34) distinct from the first throttle device (36) is arranged upstream of the second storage unit (30).
