Definitions

  • the invention is based on an electromagnetic actuator according to the preamble of claim 1, according to DE-C-198 04225.
  • Known electromagnetic actuators for actuating a Valves usually have an electromagnet that is in an effective region with a magnetic field generated by a coil via at least one pole face to a correspondingly executed Anchor surface of a displaceable anchor acts.
  • the anchor is from a starting position tightened with the anchor surface in the direction of the pole face and the valve directly from the anchor or indirectly via an anchor tappet open or closed, and usually contrary a spring force.
  • In an end position is the anchor surface on the pole surface.
  • the invention is based on an electromagnetic actuator, in particular for actuating a valve, with a first electromagnet and possibly further electromagnet, wherein the first electromagnet in a first effective range with a magnetic field generated by at least one coil over at least a first conical and / or stepped pole face a correspondingly executed anchor surface of a displaceable Anker acts.
  • electromagnet acts in at least one second effective range over at least one second pole face on a corresponding anchor surface. It can be beneficial with the first effective range a long adjustment with a from the beginning of the adjustment of relatively large force a first pole face with a steep cone or with a high Steps are reached. In addition, with the second effective range a great force in the end position, especially by a largely aligned perpendicular to the direction of movement second pole face can be achieved.
  • conical and / or stepped first Pole surface at least partially, advantageously completely arranged inside the coil.
  • the radial and axial space within the coil can be used advantageously and additional Space can be saved.
  • the second pole face in the direction of movement of the armature between the armature and the coil is arranged.
  • this is advantageously substantially perpendicular to the direction of movement executed the anchor and thus requires only a small axial space. It can be a very big part of Cross-sectional area of the coil used as a pole face and a small actuator can be achieved with a great force.
  • the first, the second or a third pole face to arrange radially outside of the coil, on a corresponding anchor surface acts.
  • the radially inner region of the second pole face can be advantageous be used to move the anchor in the direction of movement to guide two places with a great distance safely.
  • a component forming the second pole face integral with a Guide the anchor is formed. It can be a cheaper one Magnetic flux reached and it can be additional components, space, and assembly costs can be saved. Further, on small space reaches a particularly large second pole face become. However, the lead can also come from an additional Component formed with special sliding properties be.
  • the solution according to the invention can be carried out by various persons skilled in the art as meaningful electromagnetic actuators be used, but particularly advantageous in electromagnetic Actuators for actuating a valve, the in a small space a long adjustment and a possible need large force in the end position, for example with a solenoid valve for a water cycle, etc.
  • Fig. 1 shows an electromagnetic actuator for actuation a non-illustrated valve with a first electromagnet 10.
  • the electromagnet 10 acts in a first Effective region 12 with a magnetic field generated by a coil 14 16 via a first conical pole face 18 to a corresponding executed anchor surface 20 of a direction 30, 32nd slidable armature 22.
  • the armature 22 is via an anchor tappet 36 with a valve slide, not shown connected.
  • the first electromagnet 10 acts in a second Effective region 24 via a second pole face 26 to a corresponding Anchor surface 28 of the armature 22.
  • the first pole face 18 is inside the coil 14 and the second pole face 26 is in the direction of movement 30, 32 of the armature 22 between the armature 22 and the coil 14 is arranged. It becomes the radial and axial Space within the coil 14 for the first pole face 18th with a steep cone and the space in the direction of movement 30, 32 of the armature 22 between the coil 14 and the armature 22nd used for the second pole face 26, which has a shallow cone having.
  • the second pole face 26 is formed by a component 34, which is attached to a pole housing 38.
  • the pole housing 38 is closed by a lid 40, on which a coil core 42 is attached, which forms the first pole face 18.
  • the anchor 22 is about its armature plunger 36 in the coil core 42 and guided directly in a guide surface 50 in the component 34.
  • the electromagnet 10 If the electromagnet 10 is activated or the coil 14 is energized, with a coil current on the coil side 44 enters the drawing plane and on the coil side 46 exits the plane, creates a magnetic flux 48th
  • the magnetic flux 48 passes through the lid 40, the pole housing 38, the component 34, the guide surface 50, the armature 22, the armature surface 20, a working air gap 60, the first pole face 18 and over the spool core 42 to the lid 40th
  • Fig. 3 is a force-displacement diagram is shown in which a force-displacement curve 52 isolated from the first active region 12 shown is. On the abscissa is the way s and on the ordinate is the force F applied.
  • the magnetic flux 48 increases and saturates at the Guide surface 50, creates an additional magnetic flux 58 from the component 34 through the second pole face 26, via a second working air gap 62 and by the armature surface 28 to Anchor 22 ( Figure 2).
  • the second pole face 26 and the corresponding Anchor surface 28 each have a shallow cone or are substantially perpendicular to the direction of movement 30, 32 of the armature 22 executed.
  • the electromagnet 10 acts via the second pole face 26 only shortly before the end position on the corresponding anchor surface 28, but with a relatively large Force as isolated with a force-displacement curve 54 for the second active region 24 in Fig. 3 is shown.
