Definitions

  • the invention relates to a solenoid valve having a housing in which a coil wound on a bobbin, an armature, a core and a multipiece return arrangement are arranged which form an electromagnetic circuit, wherein the movable armature is mounted via bearing means in the bobbin and directly or acts indirectly on at least one valve closure member, wherein the valve closure member engages on at least one, arranged in a valve sleeve valve seat.
  • So solenoid valves are used both in pneumatic and in hydraulic circuits in vehicles, such as in braking systems, brake systems or injection systems. Furthermore, they can be used to control the pressure in pneumatic actuators or, for example, as diverter valves in turbochargers.
  • these solenoid valves are designed either as open / closed valves or as proportional control valves.
  • Such a designed as a pressure relief valve solenoid valve is known for example from DE 10 2007 002 465 AI.
  • the pressure relief valve described should have an electromagnetic part that is set as accurately as possible, to calibrate and assemble.
  • this pressure relief valve still has a variety of components that make it difficult to achieve a manufacturing optimization with regard to pre-assembly and final assembly.
  • This publication is in Incidentally, it can not be deduced how the connection between valve tappet and armature is to be carried out. However, a high degree of coaxiality between the armature and the valve tappet is a prerequisite for proper operation of the pressure relief valve.
  • the embodiment according to DE 10 2007 002 465 AI involves the risk of creating coaxial errors between the armature and the valve tappet.
  • a solenoid valve in that the core is arranged on one of the valve sleeve opposite side of the housing and the armature is constructed of several sections, wherein a first, directed to the core portion has a larger diameter than the inner diameter of a portion of the bobbin and wherein the coil carrier is formed on a side opposite the core as a valve sleeve. It is manufacturing technology particularly advantageous if at least parts of the inference arrangement are arranged in the coil carrier. For a positionally accurate mounting of the core, it is advantageous if a region of the core which is opposite to the armature has a larger diameter than a region of the coil carrier which is opposite the valve closure element. In the valve sleeve advantageously a valve stem is guided, which is connected to the armature. From a technical point of view and to avoid Koaxi Rundsmayn it is particularly advantageous if the armature and the valve lifter are integrally formed.
  • the portion of the bobbin on a bearing bush for the anchor is designed as a storage area for the anchor.
  • the bobbin can be injection molded be prepared, wherein it is advantageously made of a form and temperature stable material, such as Grivory HT2V 3HLV or Grivory XE3881.
  • a solenoid valve 1 shown in the drawing consists of a housing 2, in which a core 3, an armature 4, a bobbin 5, on which a coil 6 is wound, and a yoke assembly 7 are arranged.
  • the armature 4 is in the present case integrally connected to a valve stem 10, which acts in a known manner on a valve closure member 16.
  • the valve stem 10 is guided in a valve sleeve 22, which is formed on a core of the opposite side of the bobbin 5 and is integrally connected thereto.
  • a trained solenoid valve 1 is used as an oil pressure limiting valve.
  • a return inner section 9 is designed in one piece with the return cover section 12 facing away from the core 3 and is integrated in the coil housing 5.
  • the in-return inner and cover sections 9, 12 in the production of the Coil carrier 5 by injection molding with cast.
  • an end interference resistor 13 has already been integrated in the coil carrier 5. In this way, essential components can be provided during the pre-assembly in the bobbin 5. In the production of a standard coil component then only the selected for the valve function winding 6 must be selected and applied to the bobbin 5.
  • the solenoid valve is then completed by the arrangement of core 3, armature 4 and the associated components such as a spring 14, which holds the armature 4 in the present case under bias, and a stopper pin 15 which is adjustably arranged in the core 3 , In this case, it is helpful for the positioning if an area of the core 3 opposite from the armature 4 has a larger diameter than an area of the coil carrier 5 opposite the valve closure element 16.
  • bearing means 20 for the armature 4 are formed by the coil carrier 5, wherein the bearing region 21 substantially coincides with the region in which the return inner section 9 is provided.
  • This embodiment is made possible in that a first, directed to the core portion 4a of the armature 4 has a larger diameter than that Inner diameter of a portion 21 of the bobbin 5.
  • a part of the bobbin 5 is formed as a valve sleeve 22 for the integrally connected to the armature 4 valve stem 10 Koaxiloissmay be excluded.
  • the armature 4 and the valve stem 10 of course need not necessarily be integrally formed, they can of course also be coupled together by a positive or non-positive connection.
  • the coil carrier 5 is made of a shape-stable and temperature-stable material, for example Grivory HT2V 3HLV, Grivory XE388, PPA or PA 4.6.

Abstract

L'invention concerne une électrovanne munie d'un boîtier dans lequel sont disposés une bobine enroulée sur un support de bobine, un noyau et un système de culasse magnétique en plusieurs parties, qui forment un circuit électromagnétique. L'induit mobile est logé dans le support de bobine par l'intermédiaire d'éléments formant coussinets et agit directement ou indirectement sur au moins un élément de fermeture de vanne, ledit élément de fermeture de vanne s'appliquant sur au moins un siège de vanne monté dans un manchon de vanne. Le noyau est monté sur une face du boîtier opposée au manchon de vanne et l'induit se compose de plusieurs pièces partielles. Une première pièce partielle dirigée en direction du noyau présente un diamètre supérieur au diamètre intérieur d'une zone partielle du support de bobine et ledit support de bobine se présente, sur une face opposée au noyau, sous forme de manchon de vanne.
