Definitions

  • the present invention relates to a magnetic actuator for a
  • the magnetic actuator according to the invention with the features of claim 1 has the advantage that in this case a magnetic actuator is provided, which has an effective eddy current-minimized magnetic circuit and thus significantly shorter switching times of the valve allows. this will
  • Non-magnetic region allows a magnetic separation, wherein between the magnetic and the non-magnetic region a cohesive connection by means of a two-component metal powder injection molding process is present.
  • the production of the one-piece pole core of the magnetic actuator can be realized in a simple step as a mass part in a process step with low cycle times and unit costs.
  • two side surfaces of the non-magnetic regions of the pole core are parallel to one another, as a result of which the magnetic actuator achieves particularly high dynamics.
  • a width of the non-magnetic region is chosen so large that an electrical separation of adjacent magnetic
  • an axial extent of the pole core is greater than an axial extent of the coil housing.
  • Figure 2 is a sectional view taken along a plane A-A of
  • Figure 3 is a sectional view of the pole core according to a second
