- Internal-combustion engine-arranged injectors are connected, on each of which a solenoid valve for controlling the fuel injection is arranged.
- the fuel injection device can also be used as Fuel injection pump can be formed, through which fuel is pumped under high pressure and with which fuel injection valves arranged on the cylinders of the internal combustion engine are connected, wherein a magnetic valve for controlling the high pressure generation and thus the fuel injection is arranged on the fuel injection pump.
- the high-pressure fuel pump 10 has a pump piston 20 which is tightly guided in a cylinder bore 16 of a pump body 18 and delimits a pump working space 22 in the cylinder bore 16.
- the pump piston 20 is by a cam 24 of a camshaft
- Internal combustion engine is driven at least indirectly, for example via a rocker arm, against the force of a return spring 26 in one stroke movement.
- fuel is supplied to the pump work chamber 22 from a fuel reservoir 28, for example by means of a feed pump 29.
- the fuel injection valve 12 has a valve body 30 which is connected to the pump body 18 and which can be constructed in several parts and in which an injection valve member 34 is guided in a bore 32 in a longitudinally displaceable manner.
- An intermediate body 36 is arranged between the valve body 30 and the pump body 18.
- the valve body 30 has at least one, preferably a plurality of injection openings 38 at its end region facing the combustion chamber of the cylinder of the internal combustion engine.
- the injection valve member 34 has, for example, an approximately conical sealing surface 40 which is in contact with one in the valve body 30 whose valve region 41, which faces the combustion chamber, cooperates, from or after which the injection openings 32 lead away.
- valve body 30 there is an annular space 42 between the injection valve member 34 and the bore 32 towards the valve seat 41, which in its end region facing away from the valve seat 41 merges into a pressure space 44 surrounding the injection valve member 34 by a radial expansion of the bore 32.
- the injection valve member 34 has a pressure shoulder 46 directed towards the valve seat 41 at the level of the pressure chamber 44 due to a change in cross section.
- a prestressed closing spring 48 engages, by means of which the injection valve member 34 is pressed toward the valve seat 41.
- the closing spring 48 is arranged in a spring chamber 49 in the valve body 30 or in the intermediate body 36, which adjoins the bore 30.
- a spring 50 with a smaller diameter adjoins the spring chamber 49 at its end facing away from the pressure chamber 44.
- a control piston 51 is tightly guided in the bore 50 and delimits a control pressure chamber 52 in the bore 50.
- the control piston 51 is supported on the injection valve member 34 and, depending on the pressure prevailing in the control pressure chamber 52, generates a force supporting the closing spring 48 in the closing direction on the injection valve member 34.
- a channel leads from the pump working chamber 22 through the pump body 16, the intermediate body 36 and the valve body 30 54 into the pressure chamber 44 of the fuel injection valve 12.
- a connection 55 leads from the channel 54 to the feed pump 29 and to the fuel reservoir 28.

- the second solenoid valve 60 and the control pressure chamber 52 can also be omitted, the opening of the fuel injection valve 12 being determined only by the closing spring 48. If the pressure prevailing in the pressure chamber 44 generates a greater force on the injection valve member 34 than the closing spring 48 and the pressure prevailing in the control pressure chamber 52, the injection valve member 34 moves in the opening direction 35 and releases the injection openings 38.
- the intermediate body 36 is shown enlarged with the two solenoid valves 56 and 60 arranged therein.
- the intermediate body 36 has two recesses 61 extending from its end face facing the pump body 16, in each of which a magnetic assembly 62 of the magnetic valves 56, 60 is inserted.

- the solenoid valve member 66 of the respective solenoid valve 56, 60 is in a first position in which the connection 55, 59 is opened or closed, and when the solenoid coil 63 is energized, the solenoid valve member 66 of the respective solenoid valve 56, 60 becomes one second position moves, in which this closes or opens the connection 55, 59 accordingly.
- the magnetic assemblies 62 of the two magnetic valves 56, 60 are each held in the recesses 61 by a spring element 70.
- a spring element 70 designed as a round plate spring is provided, which clamps the magnet assembly 62 in the recess 61 in an axial direction, that is to say in the direction of the longitudinal axis of the recess 61 and the magnet assembly 62, via the respective pressure piece 65.
- the two spring elements 70 are integrally formed with one another and connected to one another via a web 71 shown in FIG. The spring elements 70 are bent in the axial direction in order to generate the required pretension.
- holding elements are integrally formed on the spring elements 70, which allow the spring elements 70 to be fixed on the intermediate body 36 and which are explained in more detail below.
- a holding element 72 in the form of a hook is formed on one of the spring elements 70.
- the hook 72 protrudes approximately radially outward from the spring element 70 and is bent in a U shape at the free end thereof.

- a further pin 76 is pressed into the intermediate body 36 and the lugs 75 laterally engage around it.
- depressions for the holding elements 72 and 75 and for the web 71 connecting the two spring elements 70 are introduced, so that they do not protrude beyond the end face of the intermediate body 36.
- the hook 72 engages around the pin 74 or is pressed onto the pin 74 and the lugs 75 grip around the pin 76, which results in a clamping connection of the spring elements 70 with the pins 74, 76, so that they can no longer fall out of the intermediate body 36.
- the spring assemblies 70 thus fix the magnetic assemblies 62 of the magnetic valves 56, 60 in the intermediate body 36 in such a way that they cannot fall out either.
- a functional test of the magnet assemblies 62 of the solenoid valves 56, 60 inserted into the recesses 61 of the intermediate body 36 is thus made possible without the risk of the magnet assemblies 62 falling out.
- the magnetic assemblies 62 inserted in the intermediate body 36 are secured against falling out by the spring elements 70 even during a subsequent transport before the final assembly of the fuel injection device.
- the pump body 16 and the valve body 30 are joined to the intermediate body 36, the pump body 16 forming a cover part through which the spring elements 70 axially are compressed and the magnetic assemblies 62 are clamped in the recesses 61 of the intermediate body 36 via them and are thus fixed without play.
- the spring element 170 is shown according to a second embodiment.
- only one spring element 170 is provided for one of the solenoid valves 56, 60.
- the spring element 170 is designed as a plate spring with a circular cross section, and a retaining element 172 surrounding it is integrally formed on it in the form of a retaining ring.
- the locking ring 172 is formed on the spring element 170 via an approximately radially extending web 171.
- the locking ring 172 is designed to be radially elastically deformable.
- the recess 161 in the intermediate body 136, into which the magnet assembly 62 is inserted, has, in its periphery near its end facing the end face of the intermediate body 136, an undercut cross-sectional enlargement 174, which can be formed by an annular groove, a depression or a bore, in which the locking ring 172 can be locked radially outwards.
- the diameter of the locking ring 172 in the relaxed state is somewhat larger than the diameter of the recess 161, wherein when the spring element 170 is inserted into the recess 161, the locking ring 172 is radially elastically compressed and in the end position of the spring element 170 relaxes outwards and in the Ring groove 174 engages.
- the spring element 170 is fixed on the intermediate body 136 and, via this, the magnetic assembly 62 is secured against falling out in the intermediate body 136.
- the spring element 170 becomes in the axial direction pressed together and thereby the magnetic assembly 62 held without play in the intermediate body 136.
