Definitions

  • the present invention relates to an injection valve for injecting a medium, in particular for injecting fuel into a combustion chamber.
  • valves in particular for fuel, wherein each injection openings are opened and closed by means of a valve needle.
  • the valve needle is usually moved by means of an actuator against a closing spring, so that a desired amount of fuel is selectively introduced.
  • the magnet armature can be decoupled from the valve needle.
  • the closing spring force, the hydraulic force and the friction forces must be overcome to open the valve.
  • these closing forces must be applied by the electromagnet, which has a high electrical energy requirement. Solutions are known which divides the moving mass of the valve needle into several sub-masses, which are coupled to one another by means of springs, guides and stop surfaces.
  • a hydraulic valve opening in common rail diesel injectors is known, but always have a return of the fuel to the tank. This return is expensive and maintenance-prone.
  • the injection valve according to the invention with the features of claim 1 uses a pressure difference between a magnet armature bottom and a top of the stop sleeve on the valve needle against the pressure on the underside of the stop sleeve, thereby the valve needle from the valve seat to lift. This reduces the energy required to open the injector. Furthermore, the pressure difference arising during a magnet armature movement between magnet armature and stop ring is used to dampen the valve needle movement. This results in a lower noise level and less wear of the injector. Furthermore, the magnetic armature movement can be selectively damped by the hydraulic cushion according to the invention after closing the valve needle.
