Definitions

  • the invention is based on an electromagnetically actuated valve according to the preamble of patent claim 1.
  • an electromagnetically actuated valve has already been proposed in which soldering or welding of the armature to the connecting tube, the guide element to the Core and with the connecting part, the intermediate part with the core end and with the connecting part and the connecting part with the valve seat body.
  • the valve manufactured accordingly has a large construction volume due 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 thermal stresses, but also that the required reliability of the connection is not guaranteed with larger wall thicknesses of the projecting parts.
  • the valve according to the invention with the characterizing features of claim 1 has the advantage that a reliable welding is achievable 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.
  • valve seat body has a circumferential groove between the valve seat and a weld seam connecting the valve seat body to the connecting part, since this reduction in cross-sectional area reduces the heat flow during welding from the weld seam into the valve seat of the valve seat body, so that the valve seat is distorted by thermal stresses is prevented.
  • the cross-sectional area of the valve seat body between a processing bore of the valve seat body and a groove base of the circumferential groove is less than a quarter of the cross-sectional area of the valve seat body, which is formed between the line of contact of the valve closing body abutting the valve seat surface and the circumference of the valve seat body by reduce the heat flow as much as possible without endangering the stability of the valve seat body.
  • the wall thickness of the reduction in cross-section of the 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 .
  • 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 actuated 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 has a core cross section 2 and has a cross-sectional reduction 40 on the circumference, is concentric with a core longitudinal axis 4, tight with the core 1 a weld seam 54 running in the cross-sectional reduction 40 and produced by means of a laser is connected.
  • 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 cross-sectional reduction 40 of the first connecting section 5 which is designed as a welding groove and which is close to one end of the part, for example of the intermediate part 6, and is delimited towards this end by a reinforcing collar 41 which extends radially beyond the base of the groove.
  • the reinforcing 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 toward the central opening 55 of the intermediate part 6, this facilitates assembly.
  • the wall thickness of the other to be welded which is substantially greater than the reduction in cross section 40 Part, here the core end 2, enables 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
  • the second connecting section 7 encompasses a holding shoulder 37 of the connecting part which is also formed with a smaller outer diameter than in the adjacent area 20th
  • 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 resting against the sliding sleeve 22, 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, for example in the form of 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 treatment 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 lies between the line of contact of the valve seat surface Valve closing body 14 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 magnet coil 3 is completely 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 ferromagnetic element.
  • the area 29 of the guide element 28 is adapted to the contour of the magnetic coil 3, an upper end section 44 which extends radially inwards partially surrounds the core 1, a lower end section 45 partially surrounds the connecting part 20.
  • the upper end section 44 is the valve closing body 14 End facing away from the core 1 connected by laser welding, the welding being formed in a simple cross-sectional reduction 46 of the upper end section 44, which only extends 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 connected to the connecting part 20 in a cross-sectional reduction 47 by means of laser welding, for example in accordance with the weld shown in FIG. 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.
  • a plastic sheathing 24 which also encloses at least the intermediate part 6 and part of the connecting part 20.
  • the color coding of the valve enables quick identification of the valve type during production, assembly or also when storing spare parts.
  • an electrical connector 26 is molded onto the plastic sheathing 24, via which the electrical contacting of the magnetic coil 3 and thus its excitation takes place.
  • the laser weldings according to the invention which are carried out in cross-sectional reductions, not only enable a compact structure of the valve, they are also distinguished by a high level of safety and reliability and simple execution.
