Definitions

  • DE 196 50 865 A1 describes a solenoid valve for controlling the fuel pressure in a control chamber of an injection valve, such as a common rail high-pressure accumulator injection system. About the fuel pressure in the control chamber, a stroke movement of a valve piston is controlled, with which an injection port of the injection valve can be opened or closed.
  • the solenoid valve comprises an electromagnet, a movable armature and a valve member moved with the armature and acted upon by a valve closing spring in the closing direction, which valve member cooperates with the valve seat of the solenoid valve and thus controls the fuel drain from the control chamber.
  • the residual air gap of the magnetic circuit is designed very small to realize extremely short switching times.
  • the residual air gap which denotes the distance between the magnetic core and the armature, is set in magnetic valves for actuating fuel injectors in fuel injection systems by means of a residual air gap disc made of a non-magnetic metal foil.
  • a compromise between the strength or stability, the hydraulic requirements and the installation specifications must always be taken into account. So far, the residual air gap disc is placed on the armature and fixed by a spring plate of the solenoid valve spring, whereby the outflow of the control or leakage amount limits over the solenoid valve spring chamber.
  • a residual air gap disk is fixed to the magnet sleeve by frictional engagement at pinching points on the end face of the magnet core facing the magnet armature.
  • the residual air gap disc is made of a ferromagnetic or non-magnetic material, such as a metallic foil, with a simple geometry.
  • the residual air gap disk according to the invention is exchangeable, without the magnetic assembly having to be disassembled for this purpose.
  • the residual air gap disc in case of malfunction is removed from the magnet assembly and either cleaned or replaced while preserving the assembled so far magnet assembly. Particles which form and deposit during the assembly of the magnet assembly do not necessarily have to be subsequently retrofitted between the residual air gap disk and the magnet core.
  • the residual air gap disk is a simple annular disk, with at least three tongues arranged on the outer circumference, the outer ends of which have a pitch circle diameter which is greater than the diameter of the magnet sleeve at the pinching points, so that an excess occurs.
  • the number of tongues is chosen so that a centering is possible. Due to the design of the residual air gap disc, this is easy and inexpensive to manufacture.
  • These tongues of the residual air gap disc in the installed state by elastic or plastic deformation the adhesion with the magnetic sleeve ago. If the magnetic sleeve has segments in the region of the pinching points, then the number of tongues depends on the number of segments, with at least opposing segments of the magnetic sleeve with tongues forming a frictional connection.
  • the residual air gap disk is fixed in a position adjacent to the end face of the magnetic core. Furthermore, the residual air gap disc is now also secured against rotation about a vertical axis, whereby openings to be provided in the magnet assembly additional Return channels can be recessed and kept accessible. Additional return passages are provided between the magnetic core and the magnet sleeve, the magnet core having axially extending apertures on its outside. These additional return channels improve the outflow behavior of the control and leakage amount in the low-pressure side return.
  • the method for mounting the residual air gap disc according to the invention is carried out, for example, such that a mounting tool receives the residual air gap disk over its entire area and only leaves out the at least three tongues arranged on the outer circumference. Applying a slight pressure, the residual air gap disc can be inserted and positioned adjacent to the magnetic core, whereby the tongues deform and are clamped at the Einklemmstellen.
  • the representation according to FIG. 1 is to take a schematic representation of a magnetic assembly of a fuel injector.
  • a magnet assembly 10 which serves to actuate a fuel injector, for example a fuel injector for a high-pressure accumulator injection system (common rail), is embedded in an injector body 12 of the fuel injector.
  • the magnet assembly 10 is located opposite a magnet armature 14 which is formed in a known from the prior art embodiment as a one-piece magnet armature, ie armature plate and armature pin of the magnet armature 14 form a component.
  • the armature 14 may be formed in two parts, ie, the anchor plate is slidably formed on the anchor bolt.
  • the armature 14 is acted upon on a flat side 16 by a solenoid valve spring 18.
  • an adjustment ring 20 is provided, which lies on the injector body 12 and at the same time serves as a support for a magnet sleeve 32.
  • the magnet sleeve 32 is provided with a in FIG. 1 Not shown clamping nut attached to the injector body 12 of the fuel injector.
  • the magnet sleeve 32 accommodates a magnetic core 22, an inner side 36 of the magnetic sleeve 32 facing an outer side 38 of the magnetic core 22.
  • a magnetic coil 24 is recessed, the magnetic core 22 rests on an annular overlap 34 of the magnetic sleeve 32, which may also be divided into segments.
  • the magnetic core 22 is open at one of the plan side 16 of the magnet armature 14 opposite end face 26 and divided by the position of the magnetic coil 24 into an inner pole 28 and an outer pole 30.
  • the magnetic core 22 is fixed within the magnet assembly 10, for example via a crimp or a welded connection.
  • the magnetic core 22 of the magnet assembly 10 comprises a passage opening in which the solenoid valve spring 18 is arranged and which simultaneously serves as a return 40 via the controlled during actuation of the solenoid valve from the control chamber of the fuel injector tax or leakage amount in the low-pressure side return, for example, a fuel injection system flowing back.
  • FIG. 2 shows that at least one axially extending recess 39 is provided on the outer side 38 of the magnetic core 22.
  • the recess 39 is formed by the difference between an outer diameter 37 of the magnetic core 22 and an inner diameter 41 of the magnetic core 22 in the region of the at least one recess 39.
  • at least one additional return channel 48 is provided between magnetic sleeve 32 and magnetic core 22 via the at least one recess 39 , whereby the control and leakage amount flows with low flow resistance, as in Fig. 1 is shown.
  • a residual air gap disk 44 is arranged at pinch points 42, adjacent to the end face 26 of the magnetic core 22, with a frictional connection between the residual air gap disk 44 and the magnet sleeve 32 at the pinch points 42.
  • the residual air gap disc 44 which is made, for example, as a thin metal foil of a ferromagnetic or non-magnetic material, is embodied in one embodiment as a circular ring 50, as shown in FIG FIG. 3 evident.
  • the formed as a circular ring 50 residual air gap disc 44 does not cover the inner pole 28 of the magnetic core 22 but only the outer pole 30, wherein the spring chamber in which the solenoid valve spring 18 is received, is freely accessible.
  • the formed as a circular ring residual air gap disc 44 is further dimensioned so that an opening of the at least one additional return channel 48 is not covered.
  • FIG. 3 shows a plan view of a residual air gap disk 44 according to an embodiment of the invention.
  • the illustrated residual air gap disk 44 is designed as a circular ring 50, with an inner diameter 54 of the residual air gap disk 44 and an outer diameter 56 of the residual air gap disk 44.
  • the inner diameter 54 of the annulus 50 formed as a residual air gap disk 44 is dimensioned so that this outer diameter of the inner pole 28 of the magnetic core 22 of Magnetic assembly 10 exceeds.
  • the inner diameter 54 of the residual air gap disk 44 can be selected such that the magnetic coil 24 is not substantially covered by the residual air gap disk 44.
  • the outer diameter 56 of the formed as a circular ring 50 residual air gap disc 44 is dimensioned so that it is less than a diameter 60 (see. FIG. 3
  • the outer diameter 56 of the annular gap 50 formed as the annular air gap disc 44 is optionally equal to or less than the inner diameter 41 of the magnetic core 22 in the area the recess 39, whereby the at least one additional return channel 48 is freely accessible.
  • tongues 46 are provided, the outer ends of which lie on a pitch circle diameter 58.
  • the pitch circle diameter 58 of the tongues 46 exceeds the diameter 60 of the magnetic sleeve 32 at the nip 42.
  • at least three tongues 46 are provided, which are arranged at a pitch 59 of 120 ° to each other.
  • Preference is given to four tongues 46, which are arranged distributed in a pitch 59 of 90 ° to one another uniformly over the outer circumference 52 of the residual air gap disk 44.
  • six tongues 46 may be provided at a pitch 59 of 60 °.
  • the number of tongues 46 on the outer circumference 52 of the residual air gap disk 44 may also be more. A higher number of tongues 46 on the outer circumference 52 of the residual air gap disk 44 and, consequently, a higher number of pinching points 42 center and increase the holding safety and the resistance to twisting of the residual air gap disk 44.
  • the number of tongues 46 is based on the design of the magnetic sleeve 32 at the pinching points 42. If the magnetic sleeve 32 is divided into segments at the nip 42, the number of tongues 46 depends on the number of segments of the magnetic sleeve 32, wherein at least opposite segments of the magnetic sleeve 32 with tongues 46 form a frictional connection and the residual air gap disc 44 is centered.
  • the tongues 46 are designed in such a way that at the pinch points 42 there is an extremely small radial force component.
  • the excess i. the difference of the pitch circle diameter 58 of the outer ends of the tongues 46 and the diameter 60 of the magnet sleeve 32 at the nip points 42 causes deformation of the tongues 46, i. the tongues 46 abut with their outer ends against the magnetic sleeve 32 and are bent against the advancing direction when the residual air disc 44 is mounted with pressure.
  • the deformation of the tongues 46 which may be both elastic and plastic, causes a frictional connection of the residual air gap disc 44 at the Einklemmstellen 42, as shown in the illustration of FIG. 4 can be seen in detail.
  • the outer diameter 56 of the residual air gap disk 44 is selected so that it is smaller than the diameter 60 of the magnetic sleeve 32 at the nip 42, so that the elastic or plastic Deformation takes place only at the tongues 46 and not along the outer periphery 52 of the residual air gap disc 44th
  • the residual air gap disk 44 Since the residual air gap disk 44 is fixed in position after assembly of the magnet assembly 10, it may be both retroactively integrated into an existing magnet assembly 10, as well as simply removed again from a magnet assembly 10.
  • the assembly of the residual air gap disk 44 takes place, for example, with a tool which receives the residual air gap disk 44 in a planar manner, but omits the tongues 46 arranged on the outer circumference 52.
  • the residual air gap disk 44 in this embodiment can be viewed from below, i. from the side of the magnet armature 14 ago, be introduced with pressure until it rests against the end face 26 of the magnetic core 22.
