Definitions
- the invention relates to a solenoid valve having a magnetic group having a magnetic coil and a magnetic core consisting of a Magnetkerninnenpol and a Magnetkernau hybridpol, and with an anchor plate and an anchor bolt, further formed by a residual air gap stop in the region of a front side of the magnetic core, wherein further between the Anchor plate and the magnet group is a residual air gap.
- Such a solenoid valve is known from DE 10 2008 040 073 A1.
- this solenoid valve stabilization that is, a significant improvement in the reproducibility, the switching operations of a solenoid valve for actuating a fuel injector to be achieved without requiring additional process steps are required and additional costs are effected.
- This is achieved in that the end face of the magnetic core or one of the front side of the magnetic core opposite anchor plate surface has at least in a certain area a deviating from a plane plane inclined and / or curved surface.
- This solenoid valve has a residual air gap disc, which is fixed by frictional connection at Einklemmstellen on the armature plate assigning front side of the magnetic core adjacent to a magnet sleeve.
- 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 disc is installed after mounting the magnet assembly and before injector assembly, the entire assembly process is not disturbed and is therefore simplified.
- the residual air gap disc has protruding tongues which are bent open during the installation process at the pinch points. In addition to the tongues and on the outer circumference of the residual air gap, a gap remains to the magnet sleeve.
- the invention has for its object to achieve a minimization of Ankerscharteriesprellens.
- Such a configuration is used in particular in fuel injectors for common rail systems with pressure-balanced solenoid valve, which allow a system pressure of about 2200 bar.
- a pressure balanced solenoid valve has a residual air gap disc to produce a residual air gap in the open state at the upper stroke stop, which should allow a quick closing of the armature.
- the problem is the anchor bounce and remindlaufurgichtsensit technically, these properties can occur especially in a multiple injection.
- the outer residual air gap for inflowing medium in the form of fuel is free, so that pressure forces from the armature space at any time reach the anchor plate top and affect the closing and bouncing behavior.
- This property is at least substantially reduced by the embodiment according to the invention.
- the described residual air gap is closed by the residual air gap disk interacting with the magnetic core outer pole, a magnet sleeve comprising the magnetic group and the armature plate. As a result of this embodiment, a tight seal is produced, in particular in this critical exterior area.
- the residual air gap disk is a circular disk.
- the annular disc formed in this way is not, as in the prior art fixed to the anchor plate, but arranged in accordance with this general embodiment in Ankerhubides floating between the armature plate and the Magnetkernau hybridpol.
- the residual air gap disk is positioned only at the outer diameter over the magnet sleeve in the radial direction.
- the inner diameter of the annular disc is selected so that on the one hand no excessive hydraulic bonding of the anchor plate takes place and on the other hand there is a sufficient closure of the outer residual air gap.
- the annular disc on inner webs which are connected to each other in the center of the annular disk and in turn in another embodiment have an opening for the anchor bolt.
- the residual air gap disc can be positioned over the anchor bolt on the armature plate and provides a closure of the residual air gap in the radial direction between Magnetkernau hybrid and the outer diameter of the anchor plate.
- this closure can be done by a shoulder in the anchor plate or alternatively in the Magnetkernau presentpol.
- the residual air gap disk is arranged only in the center of the magnet group and designed with a correspondingly smaller diameter.
- this smaller residual air gap disc is also formed as a circular disk with or without webs.
- the residual air gap disk is preferably made of a non-magnetic material.
- 1 shows a cross section through a magnetic valve with a residual air gap between a Magnetkernau builtpol a magnetic group and an outer diameter of the armature in the radial direction closing residual air gap disc
- 2 is a plan view of a formed as an annular disc residual air gap disc and a simplified cross section through a solenoid valve with a built-circular disc
- Fig. 3 is a plan view of a residual air gap disc, consisting of a circular disk with inner webs and a cross section through a simplified illustrated solenoid valve with the built-in residual air gap disk and
- Fig. 4 is a plan view of a smaller residual air gap disc analogous to FIG. 3, which is installed according to a cross section through a simplified illustrated solenoid valve in the center of the solenoid valve and wherein an armature has a residual air gap in the region of Magnetkernau touchpols closing paragraph.
- the magnet group 2 has a magnetic core inner pole 3 and a magnetic core outer pole 4, between which a magnetic coil 5 is embedded.
- the magnet group 2 is arranged in total in a magnet sleeve 6.
- the front side of the Magnetkerninnenpols 3 and the Magnetkernau combinpols 4 opposite is an anchor plate 7, in which a central passage opening 8 is inserted and into which an anchor bolt 9 is inserted.
- the armature seat of the armature plate 7 closes a control room under fuel system pressure or relieves the control chamber in the valve chamber.
- the valve chamber is interconnected via a connecting line with the control room. Due to the switching positions of the valve, the control chamber is pressurized or depressurized.
- the control chamber further cooperates with a valve needle of the fuel injector, which is axially displaced due to the different pressures in the control chamber and in an open position injection openings in the fuel injector releases flows through the (under system pressure) fuel in the associated combustion chamber of an internal combustion engine.
- the anchor bolt 9 protrudes through a central opening 10 of the Magnetkerninnenpols 3 and is surrounded in this area by a valve spring 1 1.
- the valve spring 1 1 is supported on a cover, not shown, of the magnet sleeve 6 and exerts a compressive force on the armature plate 7, which is thus moved away from the magnet group 2.
- the armature plate 7 If the magnetic coil 5 is energized, the armature plate 7 is moved against the force of the valve spring 1 1 to the magnet group 2. In this case, the armature plate 7 can only be moved so far in the direction of the magnet group 2 until it rests against a residual air gap disk 12 arranged between the magnet group 2 and the armature plate 7.
- Restluftspaltissue 12 is sealingly against the magnet sleeve 6 and prevents a backflow of fuel through the existing between the armature plate 7 and the magnet sleeve 6 gap 13 in a residual air gap 18.
- a seat bouncing of the magnet group 2 zubewegten armature plate 7 is avoided.
- the sometimes very large pressure differences between the armature plate top side facing the magnet group and the anchor plate underside with conventional design and arrangement of the residual air gap disc 12 lead to large forces and accelerations during closing of the armature plate 7 from the fuel flowing from outside the anchor plate 7 exerts, which lead to a nests bouncing of the anchor plate 7.
- the residual air gap disk 12 is shown in a plan view, wherein in this embodiment the residual air gap disk 12 is designed as a circular ring disk 14.
- the illustrated in the upper figure of FIG. 2 is shown in a plan view, wherein in this embodiment the residual air gap disk 12 is designed as a circular ring disk 14.
- FIG. 1st Cross-section through the simplified illustrated solenoid valve 1 corresponds to the illustration of FIG. 1st
- the annular disk 14 is, instead of fixed on the anchor plate 7, in the armature stroke freely floating between the armature plate 7 the Magnetkernau touchpol 4.
- the annular disc 14 is positioned only on the outer diameter of the magnet sleeve 6 in the radial direction.
- the inner diameter of the circular ring Disc 14 is chosen so that on the one hand no excessive hydraulic bonding of the anchor plate 7 takes place and on the other hand there is a sufficient closure of the outer residual air gap 18.
- the residual air gap disk 12 is also referred to as
- Annular ring 14 ' is formed and has additional internal webs 15, which are connected to each other in the center of the annular disc 14'.
- a bore 16 is embedded in this central region.
- FIG. 3 shows the corresponding cross section through the corresponding solenoid valve 1.
- FIG. 4 shows a residual air gap disk 12 reduced in size compared with the illustration according to FIG. 3, in which the outside diameter of the annular disk 14 "is significantly smaller the annular disc 14 "are merged and one ne bore 16 for the passage of the anchor bolt 9 have.
- the installation of this residual air gap disk 12 is shown in the cross section through the solenoid valve 1, in which case the anchor plate T has a shoulder 17 which closes the gap between Magnetkernau touchpol 4 and armature plate T.
- the subsequent flow from outside onto the anchor plate T is prevented or reduced by the shoulder 17 in the anchor plate T.
- the shoulder 17 in the anchor plate T must be less than the thickness of the residual air gap disc, so that the stop takes place via the residual air gap disc.
- the shoulder 17 may also be designed in one piece with the magnet group 2, in particular the magnetic core outer pole 4.
