Definitions
- the invention relates to a plastic-metal compound according to the preamble of claim 1 and of a fuel injection valve with a plastic-metal compound according to the preamble of claim 8.
- FIG. 1 shows a known prior art fuel injection valve, which has a conventional three-part construction of an inner metal flow guide part and at the same time a housing component.
- This inner valve tube is formed from an inlet port forming an inner pole, a nonmagnetic intermediate part and a valve seat carrier receiving a valve seat.
- an axially movable valve needle is arranged, which comprises an armature and a spherical valve closing body and a connecting tube connecting the armature with the valve closing body.
- the three individual components of the valve needle are firmly connected to each other by means of a cohesive joining process, in particular welding.
- an electromagnetically operable valve in the form of a fuel injection valve is already known.
- the inner valve tube forms the backbone of the entire injection valve and has in its entirety of the three individual components an essential support function.
- the non-magnetic intermediate part is connected by welds both tight and tight with the inlet port and with the valve seat carrier.
- the windings of a magnetic coil are introduced into a plastic coil bobbin, which in turn surrounds in the circumferential direction a part of the inlet port serving as inner pole and also the intermediate part.
- an axially movable valve needle is arranged, which comprises a sleeve-shaped armature and a spherical valve closing body and a connecting tube connecting the armature with the valve closing body.
- Connecting pipe is firmly connected by means of welds with the armature and also with the valve closing body.
- the valve closing body cooperates with a frusto-conical valve seat surface of a metal valve seat body.
- the valve seat body is firmly connected by means of a weld with the valve seat carrier.
- the fuel injection valve has a spherical valve-closing body cooperating with a valve seat, which is attached to a closing body carrier in the form of a plastic tube, while at the opposite end of the valve closing body, an anchor is attached to the plastic tube. Together, these components form an axially movable valve needle.
- the lower end of the plastic tube is dome-shaped, wherein in the curved recess of the valve closing body is positively held by means of a snap connection.
- the plastic tube is designed to be resilient in the region of the lower recess, since holding jaws have to embrace the valve closing body.
- the spherical valve closing body may be made of steel, a ceramic or a plastic.
- the valve closing body cooperates with a frusto-conical valve seat surface of a metal valve seat body.
- the valve seat body is firmly connected by means of a weld with the valve seat carrier.
- the plastic-metal compound according to the invention with the features of claim 1 has the advantage that it is simple and inexpensive to produce and still an automatic assembly is guaranteed.
- the plastic-metal press-fit connections can be produced in a particularly reliable and reliable manner by designing sawtooth-like structures at least on the metal component in the overlapping areas of the respective components to be connected.
- the sawtooth-like structure of the metal component penetrates into the plastic of the corresponding component and deforms it elastically, whereby a relaxation of the plastic in the sawtooth-like structure takes place.
- the inventive construction guarantees high security against loosening of the connection by pulling against the mounting direction and also offers a very high security against rotation, which is particularly desirable when the two corresponding components must remain in a certain rotational position to each other. In addition, a chip formation during assembly is excluded.
- the measures listed in the dependent claims advantageous refinements and improvements of claim 1 plastic-metal connection are possible.
- the erfmdungssiee fuel injection valve having the characterizing features of claim 8 has the advantage that a simplified and cost-effective production and automatic assembly of many individual components and thus the entire valve can be realized because of cohesive joining methods, such as welding, which have the disadvantage of heat distortion, and consuming positive connection techniques can be dispensed with. Rather, particularly advantageous press connections between a metal component partner and a component partner made of plastic can be used, which are simple and very safe and reliable attachable.
- the erfmdungsdorfe arrangement also has the advantage of a reduction of structure-borne noise and thus the noise compared to known solutions.
- the plastic-metal press connections can be made particularly secure and reliable if, in the overlapping areas of the respective components to be connected, sawtooth-like structures are formed optimized at least on the metal component.
- the sawtooth-like structure of the metal component penetrates into the plastic of the corresponding component and deforms it elastically, whereby a relaxation of the plastic in the sawtooth-like structure takes place.
- the connecting piece, the valve seat carrier and the valve needle in addition to the bobbin and the electrical connector made of a plastic, which are then firmly connected in each case with metal components of the fuel injection valve.
- the mass of the fuel injection valve can be significantly reduced. From the reduced mass of these components, there are the advantages of better dynamics of the valve and a reduced noise.
- This profiled area is designed as a knurl, which is formed by a plurality of parallel, distributed over the circumference of vertical or oblique grooves, grooves or Auf theoryfen. With this profiled area is ensured in an advantageous manner that the metal component positively and absolutely against rotation in the sleeve-shaped plastic component is fixed. In this case, the profiled area can be provided at both ends of the saw-tooth-like structure of the metal component.

- injection-molded perforated disk 34 for example of cup shape.
- the spray perforated disk 34 In the bottom part of the spray perforated disk 34 extends at least one, for example, four formed by eroding or punching ejection openings 39th
- the insertion depth of the valve seat body 29 with the cup-shaped spray disk 34 determines the default setting of the stroke of the valve needle 19.
- the one end position of the valve needle 19 is fixed at non-energized solenoid 1 by the system of the valve closing body 21 on the valve seat of the valve seat body 29, while the other end position the valve needle 19 results in excited magnetic coil 1 by the system of the armature 27 at the core end 9.
- the fuel injection valve is designed with a particularly simple and lightweight construction.
- a plurality of components of the fuel injection valve are made for example of a plastic or of a ceramic material, whereby a mass reduction of the fuel injection valve is made possible.
- the plastic extrusion coating 50 with the connector 52 and the bobbin 3 are made of a plastic, are e.g. in the embodiment of the invention still the components valve seat carrier 16 and valve needle 19 molded from a plastic. From a plastic injection of the fuel injection valve in the classical sense can therefore no longer be spoken, as several of the valve housing forming components themselves are made directly from plastic.

- the connecting tube 23 is e.g. produced by plastic injection molding and has an inner longitudinal opening, from which open several transverse openings.
- the transverse openings may optionally be provided with a mesh fabric 80 made of plastic or metal, which is attached in the injection molding process of the connecting tube 23 as an insert.
- the armature 27 has a sawtooth-like structure 63a with a "Christmas tree profile.”
- This structure 63a corresponds to an upper flared end of the connecting pipe 23 made of plastic.
- the armature 27 is pressed with its structure 63 a into the connecting pipe 23, in such a way that the structure 63 a firmly, securely and rotationally fixed hooked at the end of the connecting pipe 23 and braced.
- the connecting tube 23 is provided with a curved or dome-shaped recess 78.
- the curved receiving surface of the recess 78 ideally has a slightly smaller diameter than the diameter of the spherical valve closing body 21, whereby after attaching the valve closing body 21 by applying a low contact force, a frictional connection between the connecting pipe 23 and the valve closing body 21 is formed.
- the valve closing body 21 is pulled reliably, reliably and reproducibly out of the valve seat 30 of the valve seat body 29 via the connecting tube 23 when the magnet coil 1 is energized, although the valve closing body 21 is held "loose" on the connecting tube 23.
- a ceramic material for example Si 3 N 4 , is suitable, however, the valve closing body 21 can be metallic or ceramic or made of a plastic.
- Two further sawtooth-like structures 63 d, 63 e with "fir tree profile” are provided on a metal, magnetically conductive intermediate part 13, which is arranged below the bobbin 3 in the axial extension region of the armature 27.

- the press-in depth of the intermediate part 13 can be set in these components, where the intermediate part 13 then rests in the pressed state.
- the guide of the axially movable armature 27 is e.g. in the inner opening 66 of the intermediate part 13.
- valve seat body 29 In the lower end of the plastic valve seat carrier 16, the valve seat body 29 is inserted, which consists of a metal or ceramic material.
- the ceramic material Si 3 N 4 offers. Such a material has only about 1/3 of the mass of a comparably large component made of steel, as it is commonly used.
- the valve seat body 29 is formed on its outer periphery with a sawtooth-like structure 63 f, which may be referred to as "Tannenbaumpro hypoch.” For establishing a firm connection between the valve seat body 29 and the
- valve seat carrier 16 the valve seat body 29 is pressed with its structure 63 f in the valve seat carrier 16, in such a way that the structure 63 f hooked and spreads fixed, secure and rotationally fixed at the lower end of the valve seat carrier 16.
