  • the solenoid valves contain a magnet armature which is arranged in the region of the at least one magnet coil and serves to open and close the magnet valve.
  • the magnet armature is preferably displaceable in the axial direction by means of the magnetic coil. This means that it can be brought at least into a closed position and a release position. In the closed position, the solenoid valve is impermeable, so that a fluid can not flow from an inlet to an outlet of the solenoid valve. In the release position, however, there is a fluid connection between the inlet and outlet, the solenoid valve is thus permeable to the fluid.
  • either the closed position or the release position forms an initial position of the magnet armature, in which this is urged by a rear-part device when the solenoid is not energized, that is de-energized.
  • the armature By energizing the solenoid, the armature can be moved in the direction of the other position.
  • the armature thus serves to transmit an electromagnetic force to a closing element of the solenoid valve.
  • the closure member cooperates with a valve seat to accomplish the closing or releasing of the solenoid valve.

  • This is inventively achieved by at least one, an end face of the armature at least partially passing through, extending mainly in the radial direction radial recess.
  • the magnet armature is formed for example as a closed cap or at least partially has a cylindrical or hollow cylindrical shape.
  • the region of the end face, in which the radial recess is introduced is completely flat.

  • the axial direction runs in the direction of the longitudinal axis of the solenoid valve or the armature.
  • the radial recess has a greater extent in the radial direction than in the axial direction.
  • the radial direction is to be understood as meaning a direction which is perpendicular to the axial direction, that is to say an axis parallel to the central axis, but otherwise runs as desired. In particular, it does not have to cut (with an imaginary straight line extending the radial recess) the center of the end face of the magnet armature.
  • the radial recess is delimited by an axial recess, which may be present for example on the lateral surface of the magnet armature.
  • the radial recess is seen in longitudinal section at least partially round or rectangular.

  • the radial recess may be at least partially rectangular, so have flat surfaces which meet at a right angle to each other.
  • the radial recess is at least partially present as a groove, notch or groove or in the form of a circular cylinder, cone or truncated cone.
  • the groove is to be understood as a rectangular recess. It preferably has two flat side surfaces and a flat base surface, wherein the side surfaces are perpendicular to the base. The side surfaces run into the end face of the armature, while the base surface is in the axial direction offset to this.
  • the base is at least partially round or oval.
  • the base surface can open directly into the end face of the magnet armature.
  • side surfaces can connect to the base.
