Definitions

  • the invention is based on an electromagnetically actuated valve according to the type of the main claim.
  • Patent application P 38 25 135.3 has already proposed an electromagnetically actuated valve in which at least part of the valve is enclosed by a plastic jacket and to which an electrical connector is molded. Depending on the embodiment of the electrical connector, different Ventilu injection tools are required. This prevents inexpensive, flexible assembly.
  • valve according to the invention with the characterizing features of the main claim has the advantage of simple manufacture and assembly, which allows inexpensive series production, since only one valve extrusion tool is required for various embodiments of the electrical connector. As a result, there is greater flexibility in assembly. Another advantage is that the magnetic coil is easy to handle and electrical connector existing plastic injection molding.
  • an axial gap is formed between the end face of the core end facing the armature and a shoulder of the intermediate part, in which, by clamping, a residual air gap between the inlet end face of the armature and the core end forms the stroke of the valve closing body when opening ⁇ operation of the valve limiting non-magnetic stop disk is arranged.
  • the fuel inlet connector has a constant outer diameter over its entire length.
  • the cylinder-shaped valve seat body has a constant outer diameter.
  • a valve with the features of independent claim 6 enables a compact, short design of the valve.
  • FIG. 1 shows an exemplary embodiment of a valve designed according to the invention
  • FIG. 2 shows the independent plastic injection-molded part consisting of a magnetic coil and an electrical connector.
  • 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 fuel inlet connection 1, which is surrounded by a magnetic coil 4 and serves as a core and which, for the best possible use of space, has a constant length over its entire length. for example, has outer diameters formed by means of centerless grinding.
  • the magnet coil 4 with a coil body 2, as shown in FIG. 2 is provided with a plastic coating 7, at the same time an electrical connector 21 is also molded on, so that there is an independent plastic injection part containing the magnet coil 4 and the connector 21 .
  • the magnet coil 4 which has a stepped coil body 2 in the radial direction with a winding 13 stepped in the radial direction, in conjunction with the fuel inlet connector 1 having a constant outer diameter, enables a short and compact structure of the injection valve, as will be explained below.
  • a lower core end 3 of the fuel inlet stud 1 is kon ⁇ centrally connected to a valve longitudinal axis 5 tight "a rohrför sodium metal ⁇ lenes intermediate part 6 by welding and thereby engages with an upper cylinder portion 41, the core end 3 partially axially.
  • the stepped coil body 2 partially overlaps the fuel inlet connector 1 and, with a step 42 of larger diameter, the cylinder section 41 of the intermediate part 6.
  • the intermediate section 6 is provided at its end facing away from the fuel inlet connector 1 with a lower cylinder section 43 which has a tubular connecting part 14 overlaps and is tightly connected to it by welding.
  • a cylindrical valve seat body 8 is tightly mounted by welding.
  • the lining up of fuel inlet connector 1, intermediate part 6, connecting part 14 and valve seat body 8 thus represents a rigid metal unit.
  • the valve seat body 8 has a constant outer diameter, for example formed by centerless grinding, so that the valve seat body 8 is full ⁇ can always be used in the connecting part 14 and, due to the longer overlap, a better seal between the valve seat body 8 and the inner bore 30 of the connecting part 14 is achieved.
  • An adjusting sleeve 20 which is pushed into a flow bore 19 of the fuel inlet connection 1 and has a slot 31 in the longitudinal direction and which is formed, for example, from rolled spring steel sheet, serves to adjust the spring preload of a return spring 32 which bears against the adjusting sleeve 20 and which is downstream ⁇ supported on a connecting pipe 11.
  • a tubular armature 12 is connected by welding to the end of the connecting tube 11 facing the return tube 32 and is guided through a guide collar 15 of the intermediate part 6.
  • a valve closing body 10 which interacts with the valve seat 9 of the valve seat body 8, is connected to it, for example by soldering or welding, and is formed, for example, as a ball. Downstream of the valve seat 9 is in the valve seat body
  • Opening 33 formed.
  • the weld seam 35 between the valve seat body 8 and the connecting part 14 is from the spray opening (s) 33 and relatively far away from the valve seat 9, so that a quantity influence and leakage are effectively prevented by a distortion of the valve seat body 8 due to the high temperatures occurring during welding.
  • an axial gap 29 is formed in which a residual air gap between the inlet-side end face 26 of the armature 12 and the end face 23 is clamped the non-magnetic stop disk 27 forming the core end 3 and limiting the stroke of the valve closing body 10 during the opening process of the valve is arranged.
  • the clamped stop disc 27 protects the end face 23 of the core end 3 because of its greater bending stiffness better from wear than a loose disc, in which there is a risk of tilting and uneven striking.
  • the magnet coil 4 is surrounded by at least one guide element 16, which is designed as a bracket in the exemplary embodiment and serves as a ferromagnetic element, which extends in the axial direction over the entire length of the magnet coil 4 and at least partially surrounds the magnet coil 4 in the circumferential direction and with one end rests on the fuel inlet connection 1 and with its other end on the connecting part 14 and with these z. B. is connected by welding.
  • a part of the valve is enclosed by a plastic sheathing 18, which extends axially from the fuel inlet connection 1, via the magnet coil 4 with connector 21 and the at least one guide element 16, and thereby radially extending side faces of one on the circumference of the inlet-side end 44 of the combustion chamber material inlet connector 1 provided annular groove 25 forms.
  • the bottom of the groove which for example has a sealing ring 45, has an annular groove 25 formed by the circumference of the fuel inlet nozzle 1.
  • the plastic casing 18 engages in a holding groove 46 at the inlet end 44 of the fuel inlet connector 1.
  • the described plastic injection 7 of the solenoid 4 in connection with the injection molded connector 21 allows a high degree of flexibility in the assembly of differently designed valves, since only one injection molding tool is used for connection connectors 21 and magnetic coils 4 for producing the plastic jacket 18 is required.

Abstract

Dans les soupapes à commande électromagnétique proposées comportant une tubulure d'admission du carburant entourée d'une bobine magnétique et servant de noyau, une partie au moins de la soupape est entourée d'un revêtement en matière plastique dans lequel est enrobée une prise de raccordement électrique. Selon la forme de la prise de raccordement électrique, différents outils de recouvrement de la soupape par extrusion sont cependant nécessaires. Avec la nouvelle soupape, on effectue, en même temps que le recouvrement par extrusion de la bobine magnétique (4), un moulage par injection de la prise de raccordement électrique (21) et on produit ainsi une pièce d'un seul tenant en matière plastique moulée par injection. Pour différentes formes de la prise de raccordement électrique, un seul outil de recouvrement de la soupape par extrusion suffit, ce qui permet une plus grande souplesse dans la chaîne de montage. La soupape peut être employée comme soupape d'injection pour les systèmes d'injection de carburant.
