Definitions
- DE 196 50 865 Al describes a solenoid valve for controlling the fuel pressure in a control chamber of an injection valve, such as a common rail 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 is opened or closed.
- the solenoid valve comprises an electromagnet, a movable armature and a valve member which is moved with the armature and acted upon by a valve closing spring in the closing direction and which cooperates with the valve seat of the magnet valve and thus controls the fuel flow out of the control chamber.
- the anchor plate has a defined overtravel stop on the armature guide, which removes the kinetic energy of the movement of the armature after the electromagnet is switched off the system.
- the anchor bolt When the valve ball hits its seat, the anchor bolt is stopped in its movement.
- the anchor plate can still fly to the overstroke (ballistic operating phase) before it hits the overstroke stop.
- the part of the kinetic energy from the anchor bolt are reduced in the valve seat.
- the part of the kinetic energy from the anchor plate is dissipated in the injector body.
- valve spring exerting a closing force on the anchor bolt introduces lateral force components into the assembly of anchor plate and anchor bolt. Due to the guiding play between the armature guide and the anchor bolt, this leads to a tilting of the anchor bolt in the armature guide. In the case of a strong lateral force, this tilting can also be present in the upper position of the anchor bolt when the electromagnet is energized, since an anchor bolt stop can be present on one side. Thus, part of the set armature stroke, i. the movement of the anchor bolt in operation, not fully utilized. This leads to a lower injection quantity of fuel into the combustion chamber of an internal combustion engine.
- the invention proposes, in a two-part anchor assembly comprising an anchor bolt and an anchor plate to equip the anchor plate with an independent anchor bolt guide and to move the distance of the force application point of a valve spring of the solenoid valve on the anchor bolt to the upper end of an anchor guide.
- the maximum tilt of the anchor plate is reduced.
- Magnetic forces acting unevenly on the armature plate of the two-part armature assembly can be applied to the armature plate leading guide on the outside of the armature guide and thus do not contribute to a bending of the armature bolt, which is enclosed by the inventively proposed extended armature guide at.
- the anchor bolt Due to the reduction in the transverse forces acting on the anchor bolt, the anchor bolt is easier to move with respect to the elongated armature guide, so that reproducible injection quantities can be realized since, due to the minimization of the transverse forces, a smoother guiding of the anchor bolt in the elongated armature which surrounds it Anchor guide is accessible.
- the elongated armature guide which encloses the anchor bolt of the two-part armature assembly, on the one hand improves the smooth running of the armature Kerbolzenterrorism within the armature guide due to the achievable reduction of the transverse forces
- the elongated armature guide provides the leadership for the armature plate of the multi-part armature assembly. Due to the leadership of the anchor plate on the Jardinmantelfikiee the elongated armature guide induced by the anchor plate induced transverse forces do not act on the movable anchor armature within the anchor bolt and hinder its movement, but are absorbed by the technicallymantelfiambae the elongated armature guide.
- FIG. 1 shows the infiuence of the guide clearance between the anchor bolt and an armature guide designed according to the prior art and the tilting of the anchor bolt relative to the armature guide, shown enlarged.
- FIG. 2 shows a section through a solenoid valve, which is provided with the armature assembly according to the invention and the extended armature guide,

- FIG. 1 shows, in an enlarged view, the infiuence of the guide clearance between an anchor bolt whose anchor plate is not shown and an anchor guide according to the prior art.
- FIG. 1 shows an anchor bolt 10, which is enclosed by an armature guide 12.
- the anchor bolt 10 is acted upon by a valve spring 24. Between the upper Ringfikiee the armature guide 12 and the force application point of the valve spring 24 is a distance 22. The lateral forces between the anchor bolt 10 and the armature guide 12th arise, decrease with decreasing distance 22.
- FIG. 1 shows the anchor bolt 10 in a tilting angle ⁇ shown in relation to an injector main axis 14.
- the tilt shown in Figure 1 on an enlarged scale causes an inclination of the anchor bolt 10 within the surrounding this armature guide 12, so that a stiffness of the anchor bolt 10 due to the friction occurring at the armature guide 12 sets, and an unused Ankerhubweg ⁇ AH occurs.
- the unused Ankerhubweg .DELTA.AH can not be exploited in the lifting movement of the anchor bolt 10 relative to the stationary armature guide 12 and does not contribute to the stroke of the anchor bolt 10 and thus not to the opening movement of a valve body to be opened or closed.
- FIG. 2 a section through a solenoid valve actuating a fuel injector with the armature assembly proposed according to the invention and with an elongated armature guide is shown.
- a solenoid valve which comprises an electromagnet 32.
- an electromagnet 32 there is a two-part formed armature assembly, the anchor bolt 10 and an anchor plate 70 comprising.
- the anchor bolt 10 is enclosed by an elongated armature guide 28.
- the anchor plate 70 is guided on the outer circumferential surface of a neck 29 of the elongated armature guide 28.
- the anchor bolt 10 is acted upon by the valve spring 24.
- the distance of the force application point of the valve spring 24 and the upper side of the upper end of the elongated armature guide 28 is indicated by reference numeral 54 and considerably shorter than the distance 22 shown in Figure 1 between the force application point of the valve spring 24 and the armature guide 12 shown there according to State of the art.
- the anchor plate 70 as shown in Figure 2 is biased by an anchor plate spring 36, which in turn is supported on a disk-shaped receptacle 66 of the elongated armature guide.
- the disc-shaped receptacle 66 of the elongated armature guide 28 is by means of a clamping screw 52 on a previously screwed into the injector body 30 shim 56 and thus fixed in the injector body 30.
- the shim 56 which may be, for example, a classified shim, the Ankerhubweg is defined.
- the movement of the anchor plate 70 is bounded above by an adjusting ring 34 which is supported on the anchor bolt 10.
- a disc-shaped stop 38 of the anchor bolt 10 At the opposite end of the adjusting ring 34 of the anchor bolt 10 is a disc-shaped stop 38 of the anchor bolt 10, which abuts against the lower end face of the disc-shaped receptacle 66 of the elongated armature guide 28.
- the disc-shaped stop 38 of the anchor bolt 10 is enclosed by the classified adjustment ring 56.
- the classified adjusting ring 56 in turn rests on an end face 58 of an injection valve member guide 59.
- a control chamber 48 Within the injection valve member guide 59, a control chamber 48 is formed, which is pressurized with fuel under high pressure via an inlet throttle 50 and via a discharge throttle 46 is depressurized.
- the outlet throttle 46 can be released or closed by a closing element 42, which is of spherical design in the exemplary embodiment illustrated in FIG.
- a seat 44 is formed for the here spherically formed closing element 42 in the region of the outlet throttle 46.

- the sectional illustration according to FIG. 5 shows that the anchor plate 70 in turn has an overstroke stop 80 which cooperates with the overstroke stop 74 at the upper end of the extended armature guide 28 as shown in FIG.
- a guide surface 78 is formed, which with the outer circumferential surface of the elongated armature guide 28 as shown in Figure 3, see. there reference numeral 72, cooperates.
- the elongated armature guide 28 has the task of guiding the anchor bolt 10 inside and to provide a receptacle in the injector.
- the overstroke stop 74 on the elongated armature guide 28 shifts upward.
- the function of the guide of the anchor plate 70 is the proposed solution according to the invention now not taken over by the anchor bolt 10, but by the elongated armature guide 28.
