Definitions

  • the invention relates to a solenoid valve with an electromagnetic circuit, which consists of a wound on a bobbin coil, an armature, an adjustable core, a return plate and a yoke, wherein the movable armature is mounted via means in the bobbin and at least indirectly to a valve closure member acts.
  • an electromagnetic circuit which consists of a wound on a bobbin coil, an armature, an adjustable core, a return plate and a yoke, wherein the movable armature is mounted via means in the bobbin and at least indirectly to a valve closure member acts.
  • solenoid valves are used in both pneumatic and hydraulic circuits in vehicles, such as e.g. in brake systems, operating systems or injection systems.
  • they can be used to control the pressure in pneumatic actuators or, for example, as recirculation valves of turbochargers.
  • these solenoid valves are designed either from on / off valves or as control valves.
  • Such a solenoid valve is disclosed, for example, in DE 41 10 003 C1 and in DE 42 05 565 C2.
  • the electropneumatic pressure transducer described has a screwed into a threaded bushing core, in which case the threaded bushing can also be made in one piece with the return plate.
  • the threaded bushing can also be made in one piece with the return plate.
  • additional fine tuning can take place in that a further core is provided in the core, which can extend into a recess of the anchor.
  • the armature is mounted in one or more bearings, which in turn are arranged in a steel bushing, wherein the steel bushing is provided in the coil carrier.
  • a solenoid valve wherein the coil carrier consists of a dimensionally stable and temperature-stable material, wherein the core is arranged via a direct positive connection in the coil carrier.
  • the coil carrier can have an internal thread, in which the core is arranged adjustable by means of an external thread. In this case, however, the core should still be held by an additional security device. It is also possible that the core has a self-tapping external thread, with which the core is adjustable to arrange in the coil carrier.
  • a plain bearing bush may be provided in the coil carrier.
  • Grivory HT2V-3H LF or Grivory XE3881 has proved particularly suitable as a material which is stable in terms of shape and temperature.
  • the electromagnetic circuit 2 is closed by a return plate 7 at a first axial end of the bobbin 3 and by a yoke 8.
  • the coil carrier is made in the present case of the material Grivory HT2V-3H LF.
  • the yoke 8 surrounds the coil carrier 3 with the coil 4 wound thereon.
  • the armature 6 has a sliding layer 9, so that it is displaceably mounted in the coil carrier 3.
  • the core 5 is made in two parts and consists of an inner core piece 10 and a radially surrounding the inner core 10 and coaxially thereto outer core piece 11, which has a self-tapping thread 12.
  • the outer core piece 11 also has an internal thread, which cooperates with an external thread of the inner core piece 10, wherein the inner core piece 10 extends into a corresponding circular recess 14 of the armature 6.
  • the outer core piece 11 has at the end located to the armature 6 a circular recess 13, whose diameter is slightly larger than the outer diameter of the armature 6, so that it can dip slightly into the recess 13 during actuation of the electromagnet. These recesses serve to bundle the electromagnetic field lines.
  • the core 5 is fixedly connected to the coil carrier 3 via the self-tapping thread 12 of the outer core piece 11 and is located on the return plate 7 at.
  • This return plate 7 in turn has a connection to the yoke 8. Accordingly, the electromagnetic field lines, which arise by energizing the coil 4, pass through the armature 6 and the core 5 along the return plate 7 and the yoke 8.
  • the bipartite of the core 5 is used for fine adjustment of the air gap between the armature 6 and the core 5 and thus for adjusting the magnetic characteristic, whereby the force acting on the armature 5 can be adjusted.
  • the coarse adjustment is made by the self-tapping thread of the outer core 11th
  • An alternative embodiment is that an external thread of the outer core piece 11 cooperates with an internal thread provided in the coil carrier 3 and is held in the set state by a safety element.
  • This safety device may be a knocked-in pin, a soldering or welding point or the like.
  • other storage options for the anchor such as a coil bearing bush arranged in the coil carrier can be provided.

Abstract

L’invention concerne une électrovanne comprenant un circuit électromagnétique qui se compose d’une bobine (4) enroulée sur un porte-bobine (3), d’un induit (6), d’un noyau réglable (5), d’une tôle de reflux magnétique (7) et d’une culasse (8). Selon l’invention, l’induit mobile est logé dans le porte-bobine par le biais de moyens et il agit au moins indirectement sur un élément de fermeture de la vanne. Toujours selon l’invention, le porte-bobine (3) se compose d’un matériau indéformable et thermostable et le noyau (5) est disposé dans le porte-bobine par assemblage par coopération de formes.
