Definitions
- the axial end surface of the stop element forms the Abtungsstelle for the first axial end of the nozzle spring.
- the end face of the stop element can advantageously perform a dual function and indeed get on the one hand on the housing-side stop to the plant and on the other hand to record the first axial end of the nozzle spring.
- the end face of the stop element can thus ensure a force flow with pressure-free fluid metering device and thus also ensure that the nozzle needle then remains in its closed position and thus, in particular, no gases from a cylinder of the internal combustion engine enter the fluid metering device.
- a fuel supply port 17 is provided for coupling the fluid metering device to a fuel supply, through which the fluid metering device may preferably be supplied with fluid, in particular fuel, under high pressure, for example up to 1800 bar or more.
