Abstract (en)

[origin: WO2011088928A1] The invention relates to an injection device for injecting fuel, comprising a fuel feed path (2), along which fuel can be fed, an injector (5) having an injection opening (3), out of which the fed fuel is injected, a valve element, which is movable by means of an actuator, in order to open and close the injection opening (3), and a throttle (4), which is arranged in the fuel feed path (2). A distance (9) of the throttle (4) from the injection opening (3) along the fuel feed path (2) has a length that corresponds to a wavelength of a natural frequency of the injection device.
