Definitions
- the invention relates to a solenoid valve for controlling a Injection valve of an internal combustion engine according to the generic term of claim 1.
- Solenoid valve is used to control the fuel pressure in the Control pressure chamber of an injection valve, for example one Injector of a common rail injection system used. about the fuel pressure in the control pressure chamber becomes the movement of a Valve piston controlled with an injection opening of the injection valve is opened or closed.
- the known Solenoid valve has one arranged in a housing part Electromagnets, a movable armature and a moved with the anchor, by a closing spring in the closing direction acted upon control valve member with a Valve seat of the solenoid valve interacts and thus the fuel outflow controls from the control pressure chamber.
- a well-known disadvantage of solenoid valves their armature plate is formed in one piece with the anchor bolt, consists in so-called anchor bounces.
- anchor bounces When the magnet is switched off the armature and with it the control valve member from the closing spring of the solenoid valve accelerated towards the valve seat in order to to close a fuel drain channel from the control pressure chamber.
- the impact of the control valve member on the valve seat can cause adverse swinging and / or bouncing Control valve member on the valve seat result, whereby the control of the injection process is impaired.
- the solenoid valve known from DE 197 08 104 A1 is therefore the anchor in two parts with an anchor bolt and one anchor plate slidably mounted on the anchor bolt executed so that the anchor plate when the Control valve member on the valve seat against the clamping force a return spring moved.
- the return spring is conveyed the anchor plate then back to its starting position at a stop on the anchor bolt.
- the overtravel shim is between the anchor plate and one leading the anchor bolt Slider fixed in the housing of the solenoid valve.
- the required overstroke the anchor plate during assembly of the solenoid valve in the housing of the solenoid valve can be set, using the Thickness of the overtravel shim the way is set the anchor plate against the force of the return spring replace the control valve member on the valve seat can.
- a disadvantage is that the Over stroke adjusting disc in a complex manner under the return spring the anchor plate must be installed. For this will an intricately designed, keyhole-like opening in the overtravel shim required. As the overtravel shim continues also the distance of the pole face of the electromagnet to the anchor plate is affected by a change the strength of the overtravel adjusting disc Residual air gap affects, which makes assembly even more difficult makes.
- the solenoid valve according to the invention avoids that in the prior art disadvantages occurring and enables a considerably simpler Assembly of the anchor group.
- the anchor can be advantageous with anchor plate, anchor bolt, return spring and intermediate piece pre-assembled outside the injection valve assembly line and the required displacement or overtravel the anchor plate on the anchor bolt outside the housing of the injection valve by selecting the thickness of the intermediate piece can be set. Knowing the axial length dimension of anchor plate, slide and anchor bolt can correct thickness for the intermediate piece can be determined.
- the pre-assembled anchor group can then be in the housing of the solenoid valve can be installed. During the Assembly is done using a shim between the Slider and an inner shoulder of the solenoid valve housing the maximum opening stroke of the anchor bolt is still set.
- the intermediate part as a sickle disk form, which is pushed laterally onto the anchor bolt becomes.
- a securing sleeve pushed onto the slide piece prevents advantageous slipping of the sickle plate from the anchor bolt.
- the securing sleeve can advantageously be provided by means of locking elements be fixed on the slider.
- Fig. 1 shows the upper part of a from the prior art known fuel injection valve, which for use is determined in a fuel injection system with a High-pressure fuel storage is equipped by a High pressure feed pump continuously with high pressure fuel is supplied.
- the fuel injector shown has a valve housing 4 with a longitudinal bore in which a valve piston 6 is arranged with one end on an arranged in a nozzle body, not shown Valve needle acts.
- the valve needle is in a pressure chamber arranged by a pressure bore with high pressure standing fuel is supplied.
- Through one then connected to the pressure chamber Injection opening is used to inject the fuel the combustion chamber of the internal combustion engine.
- By lowering the valve piston 6 the valve needle in the closing direction in the Injector valve seat pressed and the injection process completed.
- the valve piston 6 is facing away from the valve needle End in a cylinder bore, which in a Valve piece 12 is introduced, which in the valve housing 4 is used.
- the front side closes in the cylinder bore 13 of the valve piston 6 a control pressure chamber 14, the via an inlet channel with a not shown High pressure fuel connection is connected.
- the inlet channel is essentially made up of three parts.
- a radial through the wall of the valve member 12 leading bore whose An inlet throttle 15 on part of its length on the inside walls form, is with a circumferential surrounding the valve piece Annulus 16 constantly connected, which annulus in turn via in constant connection with the high-pressure fuel connection stands.
- the control pressure chamber is via the inlet throttle 15 14 the prevailing in the high-pressure fuel accumulator exposed to high fuel pressure.
- valve piece 12 Coaxial to the valve piston 6 branches out of the control pressure chamber 14 in the valve piece 12 running bore, one with a flow restrictor 18 provided fuel drain channel 17, which in a Relief chamber 19 opens out with a not in Fig. 1st low-pressure fuel connection shown is connected, which in turn with a fuel return of the injection valve connected is.
- the outlet of the fuel drain channel 17 from the valve piece 12 takes place in the area of a cone countersunk part 21 of the outer end face of the valve piece 12.
- the valve piece 12 is in one Flange area 22 fixed via a screw member 23 with the valve housing 4 braced.
- a valve seat 24 is formed in the conical part 21, with which a control valve member 25 of the injection valve controlling solenoid valve 30 cooperates.
- the control valve member 25 is in shape with a two-part anchor an anchor bolt 27 and an anchor plate 28 coupled, which armature with an electromagnet 29 of the solenoid valve 30 works together.
- the solenoid valve 30 further includes a the electromagnet 29 housing part 60, which with the Valve housing 4 fixed via screwable connection means 7 connected is.
- the anchor plate 28 under the influence of their inertial mass against the preload a return spring 35 dynamically displaceable the anchor bolt 27 and is supported by this return spring in the idle state against a sickle plate fixed to the anchor bolt 26 pressed.
- the other end supports itself the return spring 35 on an overtravel 70, which rests on a slider 34 which holds the anchor bolt 27 leads.
- the slider 34 has a flange 32 which together with the overtravel 70 and another Adjustment disc 38 between a clamping shoulder 42 of the Valve housing 4 and a peripheral edge 41 of the housing part 60 is firmly clamped.
- the anchor bolt 27 and with him the armature disk 28 and that coupled to the anchor bolt Control valve member 25 are constantly housed by one supporting closing spring 31 acted upon in the closing direction, so that the control valve member 25 normally in Close position is present on valve seat 24.
- the anchor plate 28 and with it the anchor bolt become electromagnets 27 attracted by the electromagnet and thereby the drain channel 17 open to the relief chamber 19.
- the anchor bolt 27 points to the one facing away from the electromagnet 29 End of an annular shoulder 33 which, when the electromagnet is excited on an annular stop surface 37 of the slider 34 strikes and so the opening stroke of the control valve member 25 limited. Used to set the opening stroke that arranged between the flange 32 and the clamping shoulder 42 Shim 38.
- the opening and closing of the injection valve is as follows described controlled by the solenoid valve 30. How already shown, the anchor bolt 27 is constantly through the closing spring 31 acts in the closing direction, so that the control valve member 25 when the solenoid is not energized is in the closed position on the valve seat 24 and the control pressure chamber 14 is closed towards the discharge side 19, so that there is very high the inlet channel Builds up pressure that is also present in the high-pressure fuel reservoir. The pressure generates across the surface of the end face 13 in the control pressure chamber 14 a closing force on the valve piston 6 and the related valve needle, the larger is on the other hand in the opening direction in a row of the existing high pressure forces.
- FIG. 1 shows the solenoid valve in the closed state with the electromagnet switched off 29.
- the overtravel adjusting disc 70 has an elaborate keyhole-like opening 71 for the anchor bolt.
- the opening 71 is necessary to the anchor plate 28 with the socket 65 during assembly move through the opening 71 and so the sickle disk 26th to be able to slide onto the anchor bolt.
- the overtravel shim 70 limits the displacement of the anchor plate 28 on the anchor bolt 27 to the dimension d.
- the ringing the anchor plate 28 is through the over-stroke adjusting disk 70 reduced and the anchor plate 28 gets back in faster their starting position at the stop designed as a sickle disk 26 back.
- the shim 38, the flange 32nd of the slider 34 and the overtravel 70 fixed in the solenoid valve housing.
- the strength of the Overtravel 70 also affects the distance of the Armature plate 28 from the electromagnet 29.
- the manufacture of the solenoid valve and the injection valve provided with the solenoid valve is therefore quite complex and complicated.
- Fig. 2 shows an embodiment of the invention Solenoid valve.
- the same parts have the same reference numbers Mistake.
- the slider 34 is as in the state the technology with a circumferential flange 32 with an intermediate layer the shim 38 and another shim 70a, the distance between the pole face of the electromagnet 29 and the anchor plate 28 is set between the peripheral edge 41 of the housing part 60 and the Clamping shoulder 42 of the housing part 4 clamped.
- the overtravel the anchor plate 28 is different from the known 1 not by means of the shim 70a set.
- the anchor group is for better understanding of the invention with anchor plate 28, anchor bolt 27, return spring 35, intermediate piece 50 and slide 34 shown in Fig. 3 enlarged.
- the assembly of the anchor group can advantageously be outside of the injection valve housing.
- Fig. 3 shows the anchor bolt 27 in contrast to FIG. 2 in one position, which is the position of the anchor bolt when fully open Solenoid valve and thus by the electromagnet 29 tightened anchor plate 28 corresponds.
- the anchor plate 28 is from the return spring 35 to a rotating one Projection formed stop 26a pressed on the anchor bolt 27.
- the armature pin 27 points to that of the electromagnet end facing away from an annular shoulder facing the slider 33, which is pushed onto an anchor bolt Intermediate piece 50 is present.
- the intermediate piece 50 in turn is supported on an annular stop surface 37 the slider 34 from. By striking the ring shoulder 33 on the stop surface 37 with the intermediate piece interposed 50 when opening the solenoid valve becomes the maximum Opening stroke of the anchor bolt 27 and the associated Control valve member 25 limited.
- the intermediate piece can one-part or multi-part and in particular disc-shaped be trained.
- the intermediate piece is designed as a sickle disk, as shown in FIGS. 4 and 5.
- the inside diameter g of the Sickle disc is slightly larger than the groove diameter an annular groove 44 of the anchor bolt 27, in which the Sickle disc 50 is inserted.
- the annular groove 44 should be like this be sized so that the width of the ring groove is always larger is dimensioned as all the possible thicknesses c of the sickle disks.
- the axial length a of the anchor plate, the axial length b of the slider and the axial length f of the anchor bolt from the first stop 26a to the ring shoulder 33 can be measured become.
- the dimension d + e can then depend be determined by the thickness c of the sickle disk, since a and b and f are known.
- the dimension d + e corresponds to the sum of the maximum opening stroke e of the anchor bolt and the maximum Overtravel distance d of the anchor plate up to the stop on the stop surface 36 of the slider 34.
- the overtravel d can Anchor plate 28 depending on the strength, respectively Thickness c of the sickle plate 50 during the pre-assembly of the Anchor group can be set exactly.
