Definitions

  • the invention relates to a solenoid valve according to the preamble of independent claim 1.
  • a conventional solenoid valve in particular for a hydraulic unit, which is used for example in an anti-lock braking system (ABS) or a traction control system (ASR system) or an electronic stability program system (ESP system) is shown in Figure 2.
  • the conventional solenoid valve 1 comprises a magnet assembly 6 with a cover disk 7 and a housing jacket 8, a valve cartridge which comprises a capsule 20, a valve insert 10, a plunger 5, a return spring 30 and an armature 40.
  • the capsule 20 and the valve insert 10 of the valve cartridge are joined together by pressing and by a sealing weld 21, the valve cartridge is hydraulically sealed from the atmosphere.
  • the lower connection of the magnet group 6 is done by directly pressing the cover 7 on the magnetically conductive valve core 10 of the valve cartridge.
  • the valve core 10 receives the pressure forces occurring in the hydraulic system and forwards them via a caulking flange 11 onto a fluid block 9.
  • the caulking flange 11 has a first caulking region 3 with a first diameter and a second caulking region 2 with a second smaller diameter and the height 4 for caulking 12 with the flipper block.
  • the fluid block 9, on which the solenoid valve 1 is mounted by caulking, is usually made of aluminum. By caulking 12, the position of the valve cartridge is fixed in the fluid block 9 and the pressure chamber is sealed against the atmosphere. As can be seen further from FIG.
  • the solenoid valve according to the invention with the features of independent claim 1 has the advantage that a second caulking for caulking of the solenoid valve is formed with a fluid block having a second diameter which is smaller than a first diameter of a first caulking, from the housing shell of a magnetic assembly, which is joined to a valve core.
  • the part of the solenoid valve projecting from the fluid block also shortens, so that advantageously the housing volume of the overall assembly is reduced, into which the fluid block is integrated with the solenoid valve.
  • valve insert and a plunger of the solenoid valve can be shortened by the amount of lowering of the magnet assembly, whereby the height of the solenoid valve further reduced and advantageously further reductions in weight and housing volume of the entire aggregate can be achieved.
  • the magnet assembly is pressed via a cover at least partially in the caulking directly on the valve core.
  • a transition region can be arranged between the first caulking region and the second caulking region, which reduces the first diameter of the first caulking region in steps and / or continuously to the second diameter of the second caulking region.
  • Figure 1 is a schematic sectional view of a solenoid valve according to the invention.
  • Figure 2 is a schematic sectional view of a conventional solenoid valve.
  • a magnetic valve 100 comprises a magnet assembly 6, which comprises a cover disk 7 and a housing jacket 8, and a valve cartridge, which comprises a capsule 20, a valve insert 110, a plunger 105, a return spring 30 and an armature 40 includes.
  • the capsule 20 and the valve core 110 of the valve cartridge of the solenoid valve 100 according to the invention are joined together during manufacture by pressing and sealed by a sealing weld 21 against the atmosphere.
  • the valve insert 110 of the solenoid valve 100 according to the invention has for caulking 12 with a fluid block 9, for example made of aluminum, a caulking flange 111 with a first caulking region 3, which is designed with a first diameter.
  • the first diameter of the first caulking region 3 for the caulking 12 with the fluid block 9 is made larger.
  • the caulking flange 111 of the solenoid valve 100 according to the invention does not have a second caulking region 2 with a second diameter and a height 4.
  • the function of the second Verstemm Schemes 2 with the second diameter is taken over in the solenoid valve 100 of the invention from a lower portion 102 of the housing shell 8 of the magnet assembly 6, wherein the first diameter of the caulking flange 111 is increased so that the first diameter is greater than that of the second diameter Outer diameter of the housing shell 8 of the magnet assembly 6 is executed.
  • the magnet assembly 6 is shifted by the height 4 down into the fluid block 9.
  • the height of the valve cartridge of the solenoid valve 100 according to the invention by the height 4 relative to the valve cartridge of the conventional solenoid valve 1 can be shortened.
  • the connection of the magnet assembly 6 via the cover 7 is at least partially in the caulking 12, so the magnet assembly 6 is pressed via the cover 7, for example directly to the valve core 110.
  • the second caulking region 2 of the caulking flange 11 of the valve insert 5 of the conventional solenoid valve 1 is not completely eliminated, but is designed as a transitional region, which gradually and / or gradually increases the first diameter of the caulked region 3 of the caulking flange 111 of the solenoid valve 100 according to the invention. or continuously reduced to the second diameter of the second Verstemm Kunststoffs, ie As a result, the strength of the caulking 12 can be adjusted to the force flow caused by the pressure difference between the internal pressure and the atmospheric pressure.
  • the solenoid valve according to the invention can preferably be used in hydraulic units which are part of an anti-lock braking system (ABS) or a traction control system (ASR system) or an electronic stability program system (ESP system).
  • ABS anti-lock braking system
  • ASR traction control system
  • ESP electronic stability program system
