Definitions

  • the invention is based on an electromagnetically actuated valve according to the type of the main claim.
  • An electromagnetically actuated valve has already been proposed (German patent application P 38 25 135.3), in which, however, the circumference of the magnetic coil is only partially surrounded by at least one bow-shaped guide element that serves to guide the magnetic field lines .
  • the unfavorably designed magnetic field causes a high magnetic leakage flux and thus a high energy expenditure to be opened to open the valve.
  • the central fuel supply in connection with the angled electrical connector prevents the contacting of several valves by means of a common connector strip and the series connection of several valves arranged one behind the other.
  • the valve according to the invention with the characterizing features of the main claim has the advantage of a compact valve with a compact magnetic circuit.
  • a short way of the magnetic Field-forming closed field lines and the enveloping housing jacket reduce the magnetic stray flux and thus increase the ratio between useful flow and stray flux which is decisive for the energy to be used, so that less energy is required to open the valve.
  • the housing jacket enables a compact and simple design of the valve and thus also a cost-effective assembly during manufacture.
  • the metal housing shell is tightly connected to the connecting part by welding, because the necessary seal between the housing shell and the connecting part is formed at the same time.
  • the housing jacket is made by deep drawing and is tightly fitting with its upper end a 'to the core and with its lower end to the connecting part, so that harmful air gaps are avoided and welding is also simplified.
  • the housing jacket has an outwardly facing housing shoulder which, together with an end face of the plastic casing facing in the direction of the housing shoulder, forms the side surfaces of an annular groove, the groove base of which is formed by the circumference of the housing jacket.
  • the housing shoulder prevents a sealing ring mounted on the circumference of the housing casing from remaining in this receptacle when the valve is removed from a valve receptacle.
  • an annular groove is provided on the circumference of the housing jacket, the radially extending side faces of which face an end face of the plastic jacket facing the armature and an end face of one on the Housing shell drawn pull ring and the groove base is formed by the circumference of the housing shell.
  • At least one radial transverse opening serving to feed the fuel is formed between an upper sealing ring on the housing jacket and a lower sealing ring on the connecting part, said radial opening being connected to a valve space reaching as far as the valve seat.
  • the lateral fuel supply and the axially arranged electrical connecting plugs allow a series flushing of several valves arranged one behind the other with the fuel, the full integration of several valves in receptacles of the intake pipe of the internal combustion engine and the common contacting by means of a common plug connector.
  • the electromagnetically actuated valve shown in the drawing for example, in the form of an injection valve for fuel injection systems of internal combustion engines has a hollow core 1, which has a coil former 7 which is stepped in the radial direction and is provided with a winding which is stepped in the radial direction Magnetic coil 2 partially surrounds. Subsequent to a lower core end
  • a ball element 25 In the direction of the longitudinal axis 5 of the valve, a ball element 25, preferably having a hardened surface, is pressed into a core bore 17 of the core 1, the press-in depth of which determines the spring force of a return spring 26, which rests directly on the ball element 25.
  • the return spring 26 With its end facing away from the ball element 25, the return spring 26 is supported on an end face of a connecting tube 11, which is connected at its end facing the core 1 to an armature 12, which at the same time serves as a radial guide for the return spring 26, by welding.
  • a valve-closing body 10 At the end of the connecting tube 11 facing away from the armature 12, a valve-closing body 10 which is designed as a ball and which cooperates with a fixed valve seat 15 is fastened by welding.
  • a valve seat body 14 having the fixed valve seat 15 is tightly connected to the connecting part 8 by welding. Downstream of the conical valve seat 15, at least one spray opening 18 is formed in the valve seat body 14.
  • the housing shell 3 is at its upper end 35 with the core 1 by welding at least in places and at its lower end End 36 tightly connected to the connecting part 8 by welding.
  • the housing jacket 3 is designed in such a way that its upper end 35 bears closely against the core 1 and with its lower end 36 against the connecting part 8.
  • the magnetic coil 2 extends in the radial direction outward, a bottom 37 of the housing shell 3 to the larger-diameter cylindrical shell part 38 with the lower end 36.
  • the connecting part 8 has at least one radial transverse opening 20, which serves for the fuel supply, between an upper sealing ring 39 on the casing part 38 of the housing shell 3 and a lower sealing ring 40 on the connecting part 8, which extends with the valve chamber reaching to the valve seat 15 16 is in the interior of the connecting part 8 in connection.
  • the transverse opening 20 is formed in the connecting part 8, but it can also run at the height of the jacket part 38.
  • a carrier ring 32 is held, which has a fuel filter 33, through which fuel can flow to the transverse opening 20.
  • the coil body 7 of the magnet coil 2 is produced by a plastic extrusion coating, by means of which the electrical connecting plugs 30 required for contacting the magnet coil 2 are also molded on, so that an independent plastic injection molding is formed.
  • This plastic injection molded part is inserted into the housing shell 3 in such a way that it bears against the bottom 37 and the connecting plugs 30 protrude outward through through openings 45 in the bottom 37 approximately parallel to the longitudinal valve axis 5 in the direction of the upper end 35.
  • the core bore 17 is closed at its end facing away from the valve closing body 10 by a plastic plug 31, so that when a plastic jacket 22 is injected, which surrounds the end of the valve facing away from the valve seat body 14 at the bottom 37 and part of the connecting plug 30, no liquid plastic can get into the core hole 17.
  • the plastic sheath 22 extends radially beyond the bottom 37.
  • the core bore 17 is sealed off from the fuel located in the valve interior by means of the spherical element 25 pressed into the core bore 17.
  • An annular groove 47 is provided on the circumference of the casing part 38 of the casing casing 3, the radially extending side surfaces of which are directed through the end face 49 of the plastic casing 22 pointing in the direction of the armature and the end face of a pull ring 23 which is drawn onto the casing part 38 and which, for example, has a L-shaped cross-sectional shape, and the groove bottom is formed by the circumference of the jacket part 38.
  • the pull ring 23 ensures when removing the valve from a receptacle, not shown, in the intake manifold of an internal combustion engine that a. in the annular groove-mounted upper sealing ring 39 largely maintains its axial position on the circumference of the casing part 38 and does not remain in the receptacle of the suction pipe.
  • the jacket part 38 has a dashed, outwardly facing housing shoulder 48 which, together with the end face of the plastic casing 22 facing in the direction of the housing shoulder 48, forms the side faces of the annular groove 47, the groove bottom of which is formed by the circumference of the jacket part 38 is formed.
  • This solution also means that an upper sealing ring 39 mounted on the circumference of the jacket part 38 does not remain in this receptacle when the valve is removed from a receptacle of the intake manifold.
  • the lower sealing ring 40 is held on the connecting part 8 in a lower annular groove 50, which is delimited by two shoulders 51, 52 of the connecting part 8 which run radially outward from one another.
  • the armature 12 is guided in a slide opening 54 of the intermediate part 6, while the valve closing body 10 is slidably mounted in a guide opening 55 of the valve seat body 14.
  • valves according to the invention allow a series flushing of several valves arranged one behind the other and their common electrical contacting by means of a common connector strip.

Abstract

Dans les soupapes à commande électromagnétique déjà proposées, comportant un noyau entouré par une bobine magnétique ainsi qu'un induit actionnant un élément de fermeture de la soupape qui coopère avec un siège de soupape fixe, la bobine magnétique est entourée à sa périphérie par au moins un élément de guidage recourbé servant à guider les lignes de champ magnétique, ce qui provoque un flux de dispersion gênant. La nouvelle soupape est entourée au moins partiellement par une enveloppe de carter (3) métallique fermant le circuit magnétique, enveloppe qui est étroitement solidaire du noyau (1) à son extrémité supérieure (35) et de la pièce de jonction (8) à son extrémité inférieure (36) et qui dépasse, au moins dans le sens axial, par rapport à la bobine magnétique (2). Cette configuration de soupape convient en particulier pour une soupape d'injection d'un système d'injection de carburant.
