Definitions

  • the invention relates to a valve assembly for an injection valve.
  • Injection valves are in wide spread use, in particular for internal combustion engines where they may be arranged in order to dose the fluid into an intake manifold of the internal combustion engine or directly into the combustion chamber of a cylinder of the internal combustion engine.
  • injection valves are manufactured in various forms in order to satisfy the various needs for the various combustion engines. Therefore, for example, their length, their diameter and also various elements of the injection valve being responsible for the way the fluid is dosed may vary in a wide range.
  • injection valves may accommodate an actuator for actuating a needle of the injection valve, which may, for example, be an electromagnetic actuator or a piezoelectric actuator.
  • the respective injection valve may be suited to dose fluids under very high pressures.
  • the pressures may be in case of a gasoline engine, for example, in the range of up to 200 bar and in the case of diesel engines in the range of up to 2000 bar.
  • the object of the invention is to create a valve assembly which facilitates a reliable and precise function.
  • the invention is distinguished by a valve assembly for an injection valve, comprising a valve body comprising a cavity, a valve needle being axially movable in the cavity and an electro-magnetic actuator unit being designed to actuate the valve needle.
  • the electro-magnetic actuator unit comprises a pole piece being fixedly coupled with respect to the valve body and an armature part being axially moveable with respect to the valve body, wherein the pole piece comprises a first contact surface and the armature part comprises a second contact surface, wherein the pole piece and the armature part are configured to collide with each other at the respective contact surfaces.
  • the pole piece and the armature part comprise at least two different metal materials, wherein one of the metal materials has a higher hardness than the at least one other metal material, and wherein the harder metal material is located at least in a first section of the first contact surface and a second section of the second contact surface.
  • the harder metal material located at the first section of the first contact surface at least partially overlaps with the harder metal material located at the second section of the second contact surface in a radial direction with respect to a central longitudinal axis of the valve assembly.
