  • the inlet area can partially surround the main valve body.
  • the inlet area can have an outer side that is permeable to the fuel and that can be connected to an inflow of the fuel, for example this outer side can be an outer side of the valve housing and have holes for the fuel, which can then penetrate into the valve housing.
  • the tank valve device can be designed as a drain valve (so-called shut-off valve) and used for this purpose in a fuel tank and can be designed as a miniaturized shut-off valve.
  • a small size can result in the smallest possible force application surface on components outside of the tank container and the space in the bottle neck of a tank container is sufficient for assembly, as a result of which an installation location with improved assembly stability can be achieved.

  • the servo valve device comprises a spill area which is connected to the longitudinal channel or faces it and through which the fuel can be drained into the longitudinal channel.
  • the (inner) control area can connect to the longitudinal channel. If the servo valve device assumes/exercises an internal stroke through a movement of the servo valve body towards the pilot volume, a free space, for example as a gap, can be created in or on the deactivation area, through which the fuel can then flow/flow from the pilot volume into the longitudinal channel.

  • the deactivation area of the servo valve can therefore advantageously be connected to the deactivation area of the main valve. Both spill areas are connected to the line system to the pressure reducer.
  • the servo valve can be used in accordance with the way a common rail injector works Pressure drop can be generated at a closing pressure surface of a main valve, which can lead to opening of the main valve.
  • the valve housing comprises a block of material which bears against the inlet area in the longitudinal direction and in which there is a recess which comprises the pilot control volume.
