Definitions
- DE 196 501 586 A1 relates to a solenoid valve for controlling the fuel pressure in a control chamber in an injection valve such as a common rail injection system.
- a stroke movement of a valve piston is controlled, with which an injection port of the injection valve is opened or closed.
- the solenoid valve comprises an electromagnet, a movable armature and a valve member which is moved with the armature and acted upon by a valve closing spring in the closing direction and which cooperates with the valve seat of the magnet valve and thus controls the fuel outflow from a control chamber.
- a magnetic head is fixed on the injector body in such a way that the magnet is supported directly or indirectly on a shoulder in the injector body. If appropriate, a housing which encloses the magnet in a form-fitting manner can also be pressed against this shoulder.
- the fixation is usually carried out with a magnetic clamping nut, which comprises the magnet or a sleeve surrounding the magnet from above and is screwed onto an external thread located on the injector body.
- valve piece is pressurized from below with system pressure, ie the pressure level prevailing in the high-pressure reservoir (common rail).
- system pressure ie the pressure level prevailing in the high-pressure reservoir (common rail).
- the valve member is displaced within its rant notiones by a few microns up, causing the axial position of the valve seat relative to the injector depending on the system pressure, ie the pressure in the high-pressure accumulator (common rail) changes.
- both the valve seat and the upper stroke stop are displaced upward under system pressure and a system pressure-dependent reduction of the previously carefully set residual air gap occurs.
- this pressure-dependent reduction of the residual air gap is maintained when it is adjusted.
- this provision in turn means that the actually available magnetic force can not be fully utilized.
- the upper limit stop for the magnetic valve is within the first screwed connection for the magnetic head, the valve lift is reduced as a result of the displacement of the valve seat, depending on the system pressure. This is particularly disadvantageous because the displacement of the valve seat during the valve lift must be maintained and thus the desired for the stability of the switching behavior, the lowest possible valve lift at medium and small pressures is no longer present.
- a solenoid valve assembly ie, the solenoid valve in the fuel injector, is similar in most embodiments.
- a twisted magnet sleeve accommodates a magnetic coil, the magnetic core and a drain neck, which is generally produced as a rotated component.
- the hydraulic seal on the inside is done by means of one or more O-rings.
- the assembly is crimped and then carried the assembly of the connector lugs for contacting the magnetic coil and a welding of the pins. Finally, an encapsulation of the resulting preassembled module for shaping the plug geometry and the outer geometry of the magnetic head.
- a magnetic head for a solenoid valve assembly which is modular and has a clip-on plug contact.
- the radial alignment of the plug outlet can be adjusted infinitely variable.
- the male clip can be selected to accommodate different connector types and different angular outputs of the male contacts. Due to the modular design of the magnetic head with a clip-on connector, the process of flanging, the execution of a cohesive connection by welding the connector pins and the encapsulation of the magnetic head can be completely eliminated. The elimination of this work or assembly steps, a significant cost reduction can be achieved, the functionality of such a trained magnetic head of a solenoid valve assembly is maintained. In addition, can be achieved by the erfmdungsgzeß proposed solution that eliminates the magnetic clamping nut.
- the magnetic head housing is manufactured as a deep-drawn, hot or cold formed cup-shaped steel component, which includes a return pipe in its design.
- the pot-shaped component comprises an external thread, a disassembly favoring hexagon and two openings for the passage of the connector pins and finally a screwed-in groove for engaging retaining clips.
- a return pipe is formed on the pot-shaped component.
- the support of the core is possible either by using a spacer sleeve, by gluing or by using a snap ring.
- a rubber seal or a rubber plate or the like insulates the magnet core, or the magnet coil, to the injector body and takes over the sealing of the plug pins to the outside.
- the clip-on connector clip is preferably produced as an injection-molded part and comprises the inserted connector lugs.
- the connector lugs have on one side the plug geometry depending on the application purpose and on the other side the connector lugs are designed as resilient elements. As a result, when resiliently clipping the connector clips, these resilient elements can latch onto the connector pins and form a permanent connection with them, in which a self-bias is always ensured.
- the screwing or mounting of the magnetic head takes place on the already pre-assembled and equipped injector body.
- the magnetic head can be received on a screw device, for example, by means of the hexagon formed on it.
- a high-pressure tightness test and a low-pressure tightness test can be carried out, as well as quantity measurement via a removable mounting adapter.
- this can be completely dismantled, which can be carried out until after the wet test, so that no magnetic head assemblies are made as a committee.
- the plug top can be mounted in the last assembly step to avoid rejects.
- connector pin / spring element can perform a simple current or resistance test.
- the magnetic head assembly can also be completely completed first and then undergo the wet test in this form.
