Definitions
- the invention relates to a fuel injection valve according to the preamble of the main claim.
- 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 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.
- the 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 fuel injection valve according to the invention with the characterizing features of the main claim has the advantage that a simplified and cost-effective production and automatic assembly of the valve and in particular of the valve seat body can be realized because of cohesive joining methods, such as welding, which have the disadvantage of heat distortion, and complex positive connection techniques can be waived. Rather, particularly advantageous press connections between a metal component partner and a non-metallic component partner can be used, which are simple and very safe and reliable attachable.
- the arrangement according to the invention also has the advantage of reducing the structure-borne noise and thus the noise development compared with known solutions.
- the measures listed in the dependent claims advantageous refinements and improvements of the main claim fuel injector are possible.
- valve seat body is made of a ceramic
- the valve seat carrier is made of a plastic. From the reduced mass of these components, there are the advantages of better dynamics of the valve and a reduced noise.
- the plastic-ceramic press connections can be produced particularly reliably and reliably if the sawtooth-like structures are optimally formed in the overlapping areas of valve seat body and valve seat carrier.
- the sawtooth-like structure of the ceramic component valve seat body penetrates into the plastic of the valve seat carrier, and the plastic relaxes subsequently.
- FIG. 1 shows a fuel injection valve in a known embodiment according to the prior art
- Figure 2 shows an embodiment of a fuel injection valve according to the invention
- Figure 3 shows a valve seat body according to the invention
- Figure 4 is a plan view of the valve seat body of Figure 3.
- FIG. 1 shows, for a better understanding of the invention, a fuel injection valve in a known design according to the prior art.
- the example shown in the figure 1 electromagnetically actuated valve in the form of a
- Injector for fuel injection systems of mixture-compressing, spark-ignited internal combustion engines has a surrounded by a magnetic coil 1, serving as a fuel inlet nozzle and inner pole core 2, for example, here is tubular and has a constant outer diameter over its entire length.
- a coil body 3 stepped in the radial direction accommodates a winding of the magnet coil 1 and, in conjunction with the core 2, enables a compact construction of the injection valve in the region of the magnet coil 1.
- a lower core end 9 of the core 2 is concentric with a valve longitudinal axis 10 tightly connected to a tubular metal non-magnetic intermediate part 12, for example by welding and surrounds the core end 9 partially axially.
- the stepped bobbin 3 partially overlaps the core 2 and with a step 15 of larger diameter, the intermediate part 12 at least partially axially. Downstream of the bobbin 3 and the intermediate part 12 extends a tubular valve seat support 16 which is fixed to the
- valve seat carrier 16 In the valve seat carrier 16 extends a longitudinal bore 17, which is formed concentrically to the valve longitudinal axis 10. In the longitudinal bore 17, a tubular valve needle 19 is arranged, which is provided at its downstream end 20 with a spherical valve closing body 21, on whose circumference, for example, five flats 22 are provided for flowing past the fuel, for example by welding.
- the valve needle 19 represents the movable actuating part of the fuel injection valve.
- Return spring 25 or closing of the injection valve is the electromagnetic circuit with the magnetic coil 1, the core 2 and an armature 27.
- the armature 27 is connected to the valve closing body 21 remote from the end of the valve needle 19 by a weld 28 and aligned with the core 2.
- the core 2 remote from the end of the valve seat support 16 is in the longitudinal bore 17, a cylindrical metal valve seat body 29 having a fixed valve seat 30, mounted by welding tight.
- a guide opening 32 of the valve closing body 21 To guide the valve closing body 21 during the axial movement of the valve needle 19 with the armature 27 along the valve longitudinal axis 10 is a guide opening 32 of the
- Valve seat body 29 The spherical valve closing body 21 cooperates with the valve seat of the valve seat body 29, which tapers frustoconically in the flow direction.
- the valve seat body 29 is provided with an injection-molded perforated disc 34, for example in the shape of a pot concentric and firmly connected.
- 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 injection valve is largely enclosed by a plastic extrusion coating 50.
- a plastic filter 61 protrudes into the flow bore 46 of the core 2 at its inlet end 55 and ensures the filtering out of such fuel constituents that could cause blockages or damage due to their size in the injection valve.
- 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
- Fuel injection valve is enabled. While in the known fuel injection valve according to Figure 1 only 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 extrusion of the
- a plastic connecting piece 51 forms, for example, the inflow channel of the fuel injection valve and takes up the fuel filter 61.
- the bobbin 3 is for example, such that it integrally emerges from the electrical connector 52 with him.
- the valve needle 19 consists in the embodiment shown of three individual components, which together form the component valve needle 19.
- the anchor 27, e.g. is formed as a rotating part, thereby forming a first individual component, while a spherical valve-closure member 21 is a second individual component of the valve needle 19.
- a connecting tube 23 connecting the armature 27 to the valve closing body 21 constitutes a closing body carrier.
- the connecting tube 23 is e.g. produced by plastic injection molding and has an inner L Lucassöffhung, 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 plastic connecting tube 23.
- the armature 27 is pressed with its structure 63 a in the connecting tube 23, in such a way that the structure 63 a firmly hooked and secure fixed and twisted at the end of the connecting pipe 23.
- the tubular body for receiving the valve closing body 21 is 23 with a curved or dome-shaped recess 78.
- the curved Aufhahme represents the recess 78 has ideally 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 force conclusive 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.
- This annular intermediate part 13 is for example T-shaped in profile wherein two legs of the T-profile have the structures 63d, 63e and thus provide a firm secure connection to the bobbin 3 and the valve seat support 16.
- the third radially outwardly directed leg of the T-profile of the intermediate part 13 is a with a outer magnet component representing magnetic pot 14 connected by the magnetic circuit is closed.
- the valve seat body 29 is inserted into the lower end of the existing plastic valve seat carrier 16, which consists of a 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 "Christmas tree profile.”
- the valve seat body 29 with its structure 63 f in the valve seat carrier 16 in such a way that the structure 63 f hooks and spreads firmly, securely and rotationally fixed at the lower end of the valve seat carrier 16.
- the sawtooth-like structure 63 f of the ceramic component valve seat body 29 thus penetrates into the plastic of the valve seat carrier 16, and the plastic relaxes below.
- a valve seat body 29 is shown as a single component in an enlarged view.
- Different design possibilities of the saw-tooth-like structure 63 f are shown together in FIG. From the figure 3 it can be seen that the tooth shape of
- Structure 63 can be tapered in a functional manner (Za), tapered and perpendicularly tapered (Zb) or tapered (Zc) or formed in combinations.
- Figure 4 is a plan view of the valve seat body 29 of FIG 3. From the plan view it is clear that the guide opening 32 may be interrupted for the axially movable valve needle 19 with the valve closing body 21 multiple times. In this respect, the guide opening 32 forms only individual guide sections, which are formed circumferentially alternately with larger diameter flow grooves 33. Through the flow grooves 33, the fuel can be passed freely in the direction of the valve seat 30. It can also be provided only a flow groove 33.
- the energizable actuator of the fuel injection valve as the electromagnetic circuit with the solenoid coil 1, the core 2, the intermediate part 13, the magnet pot 14 and the armature 27 may e.g. also be designed as a piezoelectric or magnetostrictive drive.
