Definitions
- Patent application P 38 25 135.3 has already proposed an electromagnetically actuated valve in which the armature is soldered or welded to the connecting tube, the guide element to the core and to the connecting part, the intermediate part to the core end and to the connecting part and of the connecting part with the valve seat body.
- the valve manufactured accordingly has a large construction volume owing to the space required for the soldered or welded seams. When welding, there is a risk that the parts to be welded together deform due to thermally-induced stresses, but also that the required reliability of the connection cannot be guaranteed with larger wall thicknesses of the projecting parts.
- the valve according to the invention with the characterizing features of the main claim has the advantage that a secure connection welding can be achieved and the valve can be manufactured with smaller dimensions in the radial and axial directions.
- the simplified welding in a reduction in cross-section enables the heating of the parts to be welded to be reduced and at the same time forms a safe and reliable connection. Deformation of the parts due to the effects of temperature is therefore largely excluded.
- the cross-sectional reduction is particularly advantageous to design the cross-sectional reduction as a welding groove which is located near an end of a part to be welded and is delimited towards this end by a reinforcing collar.
- the weld groove according to the invention is not only easy to produce, the reinforcing collar also serves as protection for the weld seam and the small wall thickness in the area of the reduction in cross section. The position of the weld groove and thus also the weld seam near the ends of the part to be welded ensures a reliable connection.
- the reinforcing collar has an insertion phase and / or an edge break towards a central opening in order to make it easier to slide two cylindrical or tubular parts to be welded together.
- valve seat body has a circumferential groove between the valve seat and a weld seam connecting the valve seat body to the connecting part. This reduction in the cross-sectional area reduces the heat flow during welding from the weld seam into the valve seat of the valve seat body, so that warping of the valve seat due to thermally induced stresses is prevented.
- the cross-sectional area of the valve seat body between a processing bore of the valve seat body and a groove bottom of the circumferential groove is less than a quarter of the cross-sectional area of the valve seat body that lies between the line of contact of the valve closing body lying on the valve seat surface and the The circumference of the valve seat body is formed in order to reduce the heat flow as much as possible, but without endangering the stability of the valve seat body.
- the wall thickness of the reduction in cross section of the part to be welded in the area of the weld is approximately 0.3 mm, so that reliable welding is ensured on the one hand, but also on the other hand due to the small rings Wall thickness during welding only a reduced heat input is required.
- the wall thickness of the cross-sectional reduction of one part to be welded is significantly less than the wall thickness of the other part to be welded in the area of the weld, so that the significantly larger wall thickness of the other part ensures reliable welding and the necessary heat dissipation is guaranteed.
- FIG. 1 shows an exemplary embodiment of a valve designed according to the invention
- FIG. 2 shows the welding according to the invention of two metal parts of the valve projecting one above the other.
- the electromagnetically operable valve in the form of an injection valve for fuel injection systems of internal combustion engines, for example shown in FIG. 1, has a core 1 surrounded by a magnetic coil 3, which is tubular and through which the fuel is supplied. Subsequent to a lower core end 2, on which the magnet coil 3 is arranged, a first connecting section 5 of a tubular, metallic intermediate part 6, which comprises the core end 2, is concentric with a longitudinal axis 4 of the valve and has a cross-sectional reduction on the circumference 40, connected by a weld seam 54 which runs in the cross-sectional reduction 40 and is produced by means of a laser.
- the welding according to the invention shown in FIG. 2 of two projecting metal parts of the valve is intended to apply to all weldings of the valve in a correspondingly adapted form and shows, by way of example, the reduction in cross section 40 of the first connecting section 5 which is designed as a welding groove and which is in the vicinity of one end of the part , for example the intermediate part 6, is located and is delimited towards this end by a reinforcing collar 41 which extends radially beyond the groove base.
- the reinforcement collar 41 serves as protection for the weld seam 54 and the small wall thickness of the cross-sectional reduction 40 of approximately 0.3 mm. If the reinforcing collar 41 has an insertion phase 42 and / or an edge break towards the central opening 55 of the intermediate part 6, this facilitates assembly.
- the wall thickness of the other which is substantially greater in comparison to the reduction in cross-section 40, Eating part, here the core end 2, enables a safe and reliable welding.
- the first connecting section 5 encompasses a holding shoulder 36 of the core end 2, which has a smaller outer diameter than the core 1, and the second connecting section 7 encompasses a likewise smaller outer diameter than the neck formed in the adjacent area paragraph 37 of the connecting part 20.
- a valve seat body 8 having a groove 31 is welded into a holding bore 39, the laser-generated weld running in a reduction in cross section 52 of the connecting part 20, as shown in FIG. 2 as an example.
- the groove 31 lies between the valve seat 9 and the reduction in cross section 52.
- the lining up of the core 1, the intermediate part 6, the connecting part 20 and the valve seat body 8 thus represents a tight, rigid metal unit. Downstream of the valve seat 9, at least one spray opening 17 is formed in the valve seat body 8 .
- a sliding sleeve 22 pressed into a flow bore 21 of the core 1 serves to adjust the spring preload of a return spring 18 which bears against the sliding sleeve 22 and which is supported with its downstream end on a connecting tube 23.
- an armature 12 is connected by laser welding, in which the A cross-section reduction 51, which is designed to face away from the core end 2, runs a weld seam corresponding to that shown in FIG.
- the tubular intermediate part 6, together with a guide collar 10, also serves as a guide for the armature 12.
- this is connected to a valve closing body 14 which interacts with the valve seat 9 and is designed, for example, as a ball, for example by welding.
- the circumferential groove 31 in the valve seat body 8 causes the cross-sectional area of the valve seat body 8 between a processing bore 32 of the valve seat body 8 and a groove bottom 33 of the circumferential groove 31 to be less than a quarter of the cross-sectional area of the valve seat body 8, which is between the Contact line of the valve closing body 14 resting on the valve seat surface and the circumference of the valve seat body 8 is formed.
- This reduced cross-sectional area reduces the heat flow during welding from the weld seam 30 into the valve seat 9, so that warping of the valve seat 9 due to thermally induced stresses is excluded.
- the magnetic coil 3 is completely and at least partially surrounded in the axial direction and at least partially in the circumferential direction by at least one guide element 28, which is designed as a bracket in the exemplary embodiment and serves as a ferro-magnetic element.
- the guide element 28 is adapted with its area 29 to the contour of the magnetic coil 3, a radially inwardly extending upper end section 44 partially encompasses the core 1, a lower end section 45 partially the connecting part 20.
- the upper end section 44 is with its End facing away from the valve closing body 14 is connected to the core 1 by laser welding, the welding being formed in a simple cross-sectional reduction 46 of the upper end section 44 that extends only over part of the circumference of the guide element 28.
- the guide element 28 With its lower end section 45, the guide element 28 is laser-welded to the connecting part 20 in a cross-sectional reduction 47. bound, for example according to the weld shown in Figure 2. Since the guide element 28 does not perform a sealing function, a circumferential, tight welding is not necessary, so that the cross-sectional reductions 46, 47 at the upper end section 44 and the lower end section 45 do not have to be circumferential. In a further exemplary embodiment (not shown here), it is also possible, as at the upper end section 44 and also at the lower end section 45, to dispense with the formation of a welding groove extending over the entire circumference of the guide element 28 and only a simple one To provide a reduction in cross-section extending over part of the circumference of the guide element 28.
- a plastic sheathing 24 which also encloses at least the intermediate part 6 and a part of the connecting part 20.
- the colored identification of the valve enables quick identification of the valve type during production, assembly or also in the stocking of spare parts.
- an electrical connecting plug 26 is formed on the plastic sheathing 24, via which the electrical contacting of the magnetic coil 3 and thus its excitation takes place.
- the laser welding according to the invention which is carried out with a reduction in cross-section, not only enables the valve to have a compact structure, but is also distinguished by a high level of safety and reliability as well as being easy to carry out.
Abstract
Sur les modèles connus de soupapes à commande électromagnétique comportant un noyau, sur lequel est disposé une bobine magnétique, et un induit qui agit sur un élément de fermeture de la soupape au moyen d'un tube de raccordement, le soudage ou le brasage des éléments nécessite de disposer d'une place importante. De plus, un assemblage correct n'est pas toujours assuré. Avec la nouvelle soupape, le soudage des éléments par laser dans un rétreint, par exemple le rétreint (40), a pour effet de réduire les dimensions et produit de surcroît un assemblage fiable et exempt de fissures. Cette configuration de soupape convient en particulier pour les soupapes d'injection des systèmes d'injection de carburant.On known models of electromagnetically controlled valves comprising a core, on which is arranged a magnetic coil, and an armature which acts on a closing element of the valve by means of a connecting tube, the welding or the brazing of the elements requires an important place. In addition, correct assembly is not always guaranteed. With the new valve, laser welding of the elements into a necking, for example the necking (40), reduces dimensions and furthermore produces a reliable and crack-free assembly. This valve configuration is particularly suitable for injection valves of fuel injection systems.
