Abstract
A solenoid valve (1) which is used in particular for systems on internal combustion engines comprises an external pole (2), an internal pole (3), a magnetic coil (20) and an armature (25). In this case, the internal pole (3) is connected to the external pole (2) via a body (33) and a non-magnetically conductive separating body (32). With the magnetic coil (20) being fed with current, a magnetic closure is produced which guides the body (33), the armature (25) and the external pole (2) via the internal pole (3). A formation of the magnetic closure is enabled by the magnetically conductive body (33), via which a strengthening of the magnetic attraction force (F) acting on the armature (25) is achieved with a given working air gap (s) between the internal pole (3) and the armature (25).

But magnetic valve can also be configured as servo valve.Here is it is also contemplated that the application in air compression, the internal combustion engine of self-ignition.
Background technology
A kind of magnetic valve, especially a kind of control valve of high-pressure fuel pump by known in the A1 of DE 10 2,011 089 999.
Known magnetic valve has pole piece and the armature being axially movable, wherein, the side of pole piece constitutes the stopper section for armature.
This, pole piece is manufactured by ferrite material, especially by rustless ferritic steel.Additionally, the pole piece side for constituting stopper section is present
On the section manufactured by plasticity cold forming.Stopper section can be coated with hard chromium layers.Here, armature be embedded into annular,
In non-magnetic component.In axial direction section ground surrounds armature and section ground is surrounded and had for annular, non-magnetic component
Constitute the ferrite pole piece of stopper section, cold forming side.
It is a kind of by known in the A1 of DE 198 27 267 to be used for fuel from high pressure accumulator high-pressure injection to explosive motor
Fuelinjection nozzle in combustion chamber.Known Fuelinjection nozzle has magnetic valve, and the magnetic valve is used for by with least one
Choke valve unloading (eject position) of the throttling passage section limited by conduit wall or foundation (closed position) are in control room
Fuel pressure.Magnetic valve has along the spring and solenoid for closing direction effect, and the solenoid causes valve unit in excitation
Thus the traction of part, choke valve is opened.
Therefore, it is possible that passing through corresponding structure in the air gap region between interior pole and armature in the configuration of magnetic valve
The component of type arranges the magnetic separation portion of magnetic loop.The component can be configured to annular, such as non-magnetic component, DE 10
Situation in 2011 089 999 A1.Inside extremely can be fixed on the separating part by made by non-magnetic material.
The content of the invention
Magnetic valve with claim 1 feature of the invention has the advantage that, i.e. can realize improved configuration,
In the configuration, being drawn past by magnetic loop generation for manipulating armature has been improved particularly when the solenoid is activated
Power.
The magnetic valve that can realize proposing in claim 1 by the measure enumerated in the dependent claims it is favourable
Expansion scheme.
Therefore, can especially improve and armature is maintained at into the interior magnetic confining force extremely gone up.Here can also not led using multiple
The spacer body of magnetic and/or multiple magnetic conductors.But firm what a non-magnetic spacer body and just is provided with preferred configuration
One magnetic conductor.When the solenoid is activated, this by the suitable configuration of non-magnetic spacer body and magnetic conductor and arrangement
Jing can advantageously affect the magnetic induction line that magnetic loop is produced in other words in magnetic loop.
Spacer body can also be configured to the spacer body of magnetic conduction difference.
Magnetic conductor is made up of at least one magnetic material.Here, the magnetic material is selected from operational magnetic material
Go out, wherein, it is particularly possible to use ferrite material.
In configuration spacer body and magnetic conductor, the Beneficial Effect of magnetic induction line is important for magnetic loop.Here has
Profit, interior pole is at least substantially connected with magnetic conductor, and outer pole is at least substantially connected with non-magnetic spacer body.In addition it is favourable
, non-magnetic spacer body is at least made up of the material with Ovshinsky institutional framework substantially.Additionally or alternatively, magnet is worked as
It is favourable when being at least substantially made up of ferromagnetic material.Here, magnet can in an advantageous manner be inserted into non-magnetic point
In spacer.On the one hand magnetic conductor can be fixedly connected by this way with non-magnetic spacer body, on the other hand extremely fix with interior
Connection.
Also advantageously, magnetic conductor annular closure and/or sleeve shaped ground configuration.It is also advantageous that, non-magnetic separation
Body annular closure and/or sleeve shaped ground configuration.Therefore, non-magnetic spacer body can especially be configured as stripper loop.And therefore,
Magnetic conductor can especially be configured as the magnetic guiding loop being fixedly connected with such stripper loop.Here is it is further advantageous that magnetic conductor has
Axially extending connection lip, the radial thickness reduction of magnetic conductor on the connection lip, and non-magnetic spacer body have built-in
Groove, the connection lip of magnetic conductor is placed in the groove.Thus, the company especially between magnetic conductor and non-magnetic spacer body
Connect the cylindrical sleeve shape inner face of the composite construction that can obtain being made up of in region spacer body and magnetic conductor.Additionally, this can be in structure
Pole targetedly positions and tolerance related to this with high-precision in realizing during type composite construction.
Also advantageously, the such configuration of magnetic conductor so that when solenoid is powered, due to can be real by magnetic conductor
The shaping of existing magnetic loop, in the case that the working gas gap between interior pole and armature is given, at least in the impulse stroke of magnet
Realization on region is applied to the increase of the magnetic attraction on armature.It means that arranging non-magnetic compared to magnetic conductor is replaced
The configuration of spacer body, in the case that the working gas gap between interior pole and armature is given, by the configuration of magnetic conductor work is realized
