Definitions

  • a magnetic valve has a housing provided with an aperture and a valve member movable in the housing between two positions in which it respectively opens and blocks the aperture.
  • An armature of ferromagnetic material is connected to the valve member for movement with the same and provided with a predetermined number of axially successive outer circumferential grooves.
  • Winding means cooperates with the armature for moving the same when energized and has a number of discrete disc-shaped annular windings surrounding the armature, this number corresponding to the predetermined number of grooves in the armature. Each of these windings constitutes a discrete electromagnet whose magnetic field acts upon the armature.
  • the present invention relates to a valve, and more particularly to a magnetic valve.
  • the present invention relates to magnetic valves having a rapid response time.
  • Valves of this type are used in a variety of applications, and are particularly advantageous in conjunction with electronically controlled fuel injection devices for high-revolution internal combustion engines.
  • valves and particularly magnetically operated valves, are already known.
  • they have structural characteristics which may be summarized by stating that the relationship between the mass of the valve bodyor reference to the mass of the armature is small, that the relationship of the magnet pole surfaces is large with reference to the mass of the armature, and that the used magnetic materials have as low as possible a remanenz induction with the winding being as of low inductivity as possible.
  • a magnetic valve which, briefly stated, comprises a valve housing having an aperture and a valve member movable between two positions in which it respectively opens and blocks this aperture.
  • An armature of ferromagnetic material is provided and is connected to the valve member for movement with the same, and it is formed with a predetermined number of axially successive outer circumferential grooves.
  • Winding means cooperates with the armature for moving the same when energized and has a number of discrete disc-shaped annular windings which surround the armature and each of which constitutes a discrete electromagnet whose magnetic field acts upon the armature. The number of discrete windings corresponds to the predetermined number of circumferential grooves in the armature.
  • FIGURE is a cross section through a diagrammatically illustrated magnet valve, according to the present invention.
  • the winding means of this magnetic valve is composed of a plurality of discrete disc-shaped annular windings 10. These are arranged in axially succession and between each two successive windings, there is positioned a disc 11 of ferromagnetic material. The windings are so constructed that the polarity of the magnetic field strength differs from disc to disc. Because the windings 10 and the members 11 are all annular, they together surround a substantially cylindrical space in which there is located an armature 12 which is movable in axial direction of this space.
  • the armature 12 is configurated as a hollow cylindrical member and guided by a guide cylinder 13 for axial movement.
  • the cylinder 13 itself is of hollow cylindrical configuration and connected at its upper portion with the valve housing.
  • the valve housing has a cylindrical center portion 14 in which the windings 10, the members 11 and that portion of the armature 12 which is permeated by the magnetic fields are arranged.
  • a projection 15 extends from the cylindrical center portion 14 of the housing, and at its lower end the projection 15 is provided with an aperture 16 through which the fuel to be injected into a nonillustrated internal combustion engine, exits.
  • the aperture 16 is closed by a valve member 17 which is connected with the armature 12 and movable between two positions in one of which it closes the aperture 16, as illustrated in the drawing, and the other of which it is withdrawn from the aperture and permits fuel to pass through the same.
  • a spring 19 is provided which cooperates with the armature l2 and a cover 18 which extends from above into the cylindrical portion 14 of the valve housing, urging the armature 12 and thereby the valve member 17 to valve-closing position which is illustrated in the drawing.
  • a nipple 20 is provided on the cover 18 for connection of a nonillustrated fuel supply conduit or tube. Fuel which is to be injected into the nonillustrated combustion engine enters through the nipple 20 and thereby the cover 18, and passes into the interior of the cylinder 13, from there into the projection 15, and from there through the aperture 16 when the same is opened, that is when the windings 10 are energized.
  • a nut 21 presses the cover 18 against, or rather towards the windings 10, so that the latter and the members 11 are immovably held in place.
  • the nut 21 cooperates with screw threads provided on the inner circumferential surface of the housing portion 14, as shown. Also secured to the cover 18 is the guide cylinder 13 for the armature 12.
  • the outer circumferential surface of the armature which faces the surrounding windings 10 is provided with a plurality of axially arranged circumferential grooves, whose number corresponds to the number of the windings or members 11, that is to the number of electromagnets thus provided.
  • the conductors to the individual windings 11 pass to a connector 22 on the one hand, and at the other hand, are connected at 23 with the housing of the valve which housing in turn is connected with mass when it is installed in a combustion engine.
  • energization of the winding means causes the development between any two adjacent members 11 of the two poles of the electromagnet.
  • the magnetic flux issues from one of these members 11 consisting of ferromagnetic material, and passes from there into one of the grooves which in nonenergized condition is still somewhat slightly offset with reference to the particular member 11, and from this groove it passes into the next adjacent member 11, also consisting of ferromagnetic material.
  • Each disc magnet constitutes or forms a magnetic circuit so that the system of disc magnet and grooved armature, may be considered and calculated as a plurality of unwound rotary magnets.
  • each disc II is approximately juxtaposed to one of the grooves 12.
  • valve constructed according to the present invention has extremely short response times and is therefore particularly well adapted for use in application where such short response times are desirable and required, such as in conjunction with fuel injection devices for high-revolution in ternal combustion engines.
  • a magnetic valve comprising a valve housing having an aperture; a valve member movable between two positions in which it respectively opens and blocks said aperture; winding means accommodated in said valve housing and composed of a plurality of coaxial ferromagnetic disk-shaped annuli each having an inner marginal portion and arranged in alternating sequence with a plurality of disk-shaped annular windings coaxial with one another and with said annuli; each of said windings constituting a discrete electromagnet a hollow cylindrical armature of ferromagnetic material connected to said valve member for movement therewith and located within the confines of said annuli and windings, said armature having an outer circumferential surface provided with a plurality of axially successive circumferential grooves corresponding in number to said windings and each of which is in only partial registry with the inner marginal portion of one of said annuli in the unenergized condition of said winding means; and a hollow guide sleeve for said armature accommodated in said valve housing and extending at least in part into said armaco
