摘要： An apparatus for delivering fuel to a combustion engine comprises a fuel pump (110) with an electromagnetic or piezoelectric actuator (203) for driving the piston (202) and a fuel injector (106) that is hydraulically and mechanically coupled to an outlet (210) of the fuel pump (110). The fuel injector (106) comprises an open state in which a flow-through of the fuel through the fuel injector (106) is enabled and a closed state in which the flow-through of the fuel through the fuel injector (106) is prevented, wherein the fuel injector is designed to be shifted from the closed state to the open state due to the pressure affected by the pressurised fuel of the fuel pump (110).
