Definitions
- the invention relates to a solenoid valve according to the Preamble of claim 1.
- a Solenoid valve is for example from EP 0 690 223 A2 known.
- the solenoid valve described there becomes Control of an electrically controlled Fuel injector used.
- Such a solenoid valve is also from DE 196 50 865 A 1 known. There a solenoid valve is suggested whose magnetic armature is made in several parts. To a Swinging of an armature disk after closing the Avoiding the solenoid valve is one here on the solenoid armature Damping device provided.
- the solenoid assembly is typically screwed to an injector body or injection valve housing via a solenoid clamping nut.
- a disadvantage of this screw connection proves that it requires a relatively complex and costly assembly.
- the solenoid tension nuts can come loose during operation of the solenoid valve, as a result of which the reliability and effectiveness of the solenoid valve can be impaired.
- Magnetic clamping nuts must be made from a relatively hard material. Steel alloys such as ETG 100 can be mentioned as typical materials.
- An object of the invention is to provide a improved connection possibility for magnetic assembly and Injector body of a solenoid valve.
- Solenoid valves are the subject of the dependent claims.
- the retaining ring have two crimped edges has that with corresponding grooves and / or projections the magnet assembly or the injector body interact. With the formation of two flanged edges is a very constant connection between Magnetic assembly and injector body ensures that proves to be robust and reliable.
- the retaining ring is more elastic than Magnetic clamping nuts designed.
- the necessary elasticity results from the specific circumstances, whereby as preferred materials for the connecting ring stainless Steel alloys such as alloys 1.4303 or 1.4301 are to be mentioned.
- the retaining ring with a lateral recess is formed.
- Such Recess can be used as a predetermined breaking point or predetermined breaking point serve so that the retaining ring for easy release the connection of the magnet assembly and injector body is removable. With this possibility of removal the retaining ring ensures that when disassembling of the solenoid valve no contamination occurs. In particular, particle formation or Grinding abrasion can be prevented, which when loosening conventional magnetic clamping nuts occurred.
- the magnet assembly 12 is by means of a magnetic clamping nut 14 with an injector body 13 connected.
- the magnetic clamping nut 14 does not have a individual recognizable screwing station on the one Open-end wrench can be used to tighten the magnetic clamping nut is.
- the disadvantage here is that the Magnetic clamping nut 14 itself when tightened in this way oval shaped. It can also cause plastic deformation the sleeve 12a come. Furthermore, it can by the Interaction between mother and key to one Particle removal comes, reducing the risk of pollution of the solenoid valve and the assembly lines.
- Solenoid valve A preferred embodiment of the invention Solenoid valve is shown in Figures 2 and 3.
- the solenoid valve is designated here overall by 21. It has a magnet assembly 22 and an injector body 23 on. You can also recognize one by the injector body trained connection piece 28, which for example for the connection of a pressure hole of the solenoid valve a high pressure accumulator is provided.
- the retaining ring 24 has a first one Flanged edge 24a and a second flanged edge 24b.
- the Flanged edge 24a acts with a lower groove 23a of the Injector body 23 together. It can be seen that the retaining ring 24 to form the flanged edge 24a in the groove 23a of the Injector body 23 is crimped.
- the second flanged edge 24b comprises a shoulder rest 22b a sleeve 22a of the magnet assembly 22. It should be noted that the sleeve 22a is a deep-drawn component can act.
- the assembly shown is expediently carried out Solenoid valve in that first the retaining ring 24 the injector body 23 is placed, and then the Retaining ring in the lower groove 23a of the injector body 23 is flanged. Then the magnet assembly 22 mounted or in connection with the injector body brought. Afterwards, the Magnetic assembly 22 with a hold-down on the Injector body 23 pressed while the second Flanging process to form the second flanging edge 24b he follows. It proves to be particularly advantageous that the second flanging process the shoulder pad 22b elastic is deformable, thereby producing the second Flanged edge 24b is simplified. A plastic one Deformation of the shoulder rest 22b does not take place.
- the retaining ring thus holds the magnet assembly and the Injector body together.
- the flanged edges 24a and 24b grip in the groove 23a of the injector body 23 or around the shoulder rest 22b of the sleeve 22a.
- Figure 3 is an uncut side View of the solenoid valve shown in Figure 2.
- the already explained with reference to Figure 2 Components are provided with the same reference symbols here.
- the retaining ring 27 can be disassembled by this lateral recess 23 is torn open.
