Abstract

The invention pertains to a fuel injection device operating according to the solidstate energy storage principle, whereby a rotor element carried in a pump housing of an electromagnetically driven reciprocating pump is accelerated almost without resistance, whereby the rotor element stores kinetic energy and impacts on a piston element, so that a pressure impulse is generated in the fuel contained in a closed pressure chamber before the piston element due to the fact that the stored kinetic energy of the rotor element is transferred via the piston element to the fuel in the pressure chamber and whereby the pressure impulse is used for the injection of fuel through a nozzle and whereby the rotor element is carried form-locking on the piston element and the two elements are mutually spring-mounted.
