Between the penholder 55 and the slider element 49 there is a valve spring 57 , which is biased so that it the slider element 49 against the operating rod 43 in the cylinder element 51 protrudes, presses.

The following is based on the 2 and 3 the structure of the bracket element 39 described in more detail. The bracket element 39 is from a metal plate 59 , the four right angles curved sections 61 has formed, wherein the bracket element 39 Overall, a frame-like, seen from the side rectangular shape. Instead of the metal plate 59 may differ from the embodiment shown, another plate-shaped material (so-called flat material) to form the strap member 39 be used.

A first front page 63 of the bracket element 39 has a first circular opening 65 on, by one around the opening 65 circumferential and outwardly extending collar 67 is limited and the inner diameter of an outer diameter of a connecting portion 69 of the connector 15 (please refer 1 ) is tuned. The connecting section 69 of the connector 15 is with the collar 67 of the bracket element 39 preferably firmly connected by a pressure. One of the first front page 63 of the bracket element 39 opposite second end face 71 of the bracket element 39 has a second circular opening 73 whose inner diameter to an outer diameter of an anchoring portion 75 the magnet sleeve 46 (please refer 1 ) is tuned. The anchoring section 75 the magnet sleeve 46 is inside the second opening 73 of the bracket element 39 arranged such that the magnet sleeve 46 with respect to the bracket element 39 has a small radial clearance in the order of a few hundredths to tenths of a millimeter. Between the bracket element 39 and the magnet sleeve 46 So there is a gap that is about 0.05 mm to 0.1 mm in the embodiment shown.

At an area 77 on the second front side 71 of the bracket element 39 a first end section overlaps 79 the metal plate 59 of the bracket element 39 with a second end portion 81 the metal plate 59 , In the area 77 in which also the second opening 73 of the bracket element 39 located, has the bracket element 39 due to the overlap of the two end sections 79 . 81 a double wall thickness. The two end sections 79 . 81 each have four attachment points 83 on, with each attachment point 83 of the second end portion 81 an attachment point 83 of the first end section 79 opposite. Over the opposite attachment points 83 are the two end sections 79 . 81 connected with each other. These compounds can be formed for example by Krimpverbindungen or laser welding connections. In embodiments not shown, the bracket element 39 one out of four different number of attachment points 83 on.

Furthermore, the bracket element comprises 39 between his two end faces 63 . 71 two long sides 85 , Every long side 85 indicates one of the coil arrangement 24 facing side 86 an outward facing impression 87 on. An inner radius of the impression 87 corresponds at least in Essentially an outer radius of the coil assembly 24 ,

The 4 to 6 show the entire magnet assembly 19 , You realize that the first section 31 the plastic extrusion 29 with a side surface 88 of the bracket element 39 Aligns and that one edge 89 on an inner side of the stirrup element 39 to the first section 31 borders. Out 5 it can be seen that the coil carrier 21 protruding ribs 90 which, in the plastic extrusion 29 protrude. In the embodiment shown, the ribs are 90 designed as so-called melting ribs, which during encapsulation of the coil assembly 24 with the plastic extrusion 29 at least partially with a material (plastic in the embodiment shown), from which the plastic extrusion 29 is formed, merge. The coil carrier 21 and the plastic coating 29 thus together form a seal which the coil 23 seals to the outside, so that, for example, corrosion of the coil 23 is avoided due to penetrating spray water.

7 shows a high pressure fuel pump 93 as part of a fuel system 95 an internal combustion engine 97 , A fuel storage tank 99 is via a pre-feed pump 101 with the quantity control valve device 11 connected. The quantity control valve device comprises the valve assembly 17 on that with the electromagnetic actuator 13 is coupled. The quantity control valve device 11 is via a designed as a check valve inlet valve 103 with a workroom 105 the high pressure fuel pump 93 whose volume is connected by means of one in the working space 105 reciprocating pump piston 107 can be changed. The workroom 105 is via a likewise designed as a check valve exhaust valve 109 with a high-pressure accumulator 111 connected. To the high-pressure accumulator 111 is an injector 113 that is a combustion chamber of the internal combustion engine 97 is assigned, connected.

When operating the fuel system 95 becomes fuel 115 from the pre-feed pump 101 acted upon by a prefeed pressure. The pump piston 107 is in a float, and the work space 105 is periodically enlarged and reduced. At an enlargement of the working space 105 (Suction stroke) gets fuel 115 from the pre-demand pump 101 via the at least partially opened quantity control valve device 11 and the likewise opened inlet valve 103 in the workroom 105 , In a subsequent reduction of the work space 105 (Delivery stroke) is the in the work space 105 located fuel is subjected to a pressure which is so high that the exhaust valve 109 opens and the fuel 115 in the high-pressure accumulator 111 arrives. The injection valve 113 leads to the combustion chamber of the internal combustion engine 97 appropriate amounts of fuel at certain times 115 to. To a pressure in the high-pressure accumulator 111 To keep constant, the electromagnetic actuator 13 the quantity control valve device 11 controlled such that a delivery rate of the high-pressure pump 93 on average, the fuel consumption of the internal combustion engine 97 at least substantially corresponds. The electromagnetic actuator 13 the quantity control valve device 11 and the injection valve 113 are controlled by a control unit, not shown.

How out 1 can be seen, is the quantity control valve device 11 with de-energized coil 23 in the closed state. Will the coil 23 supplied with a current, the result is a magnetic flux from the connector 15 in the bracket element 39 and from there first into the magnetic sleeve 46 and then into the magnet armature 45 is directed. From the magnet armature 45 the magnetic flux returns to the connector 15 , A throttling of the magnetic flux through the from the radial play between bracket element 39 and magnet sleeve 46 resulting gap is at least largely avoided by the fact that the bracket element 39 at its second opening 73 has the double wall thickness. The higher a current through the coil 23 flowing stream, the larger one is in the direction of the longitudinal axis 35 based on 1 to the left on the magnet armature 45 acting magnetic force. The larger the magnetic force, the more the actuating rod pushes 43 the slider element 49 against the spring force of the valve spring 57 to the left. That is, by adjusting the current, it can be determined to what extent the slider element 49 the control openings 53 covered. It can therefore an opening degree of the quantity control valve device 11 be set.

When applying the coil 23 with the current being in the coil 23 an ohmic power loss in the form of heat released by the coil 23 essentially via the bracket element 39 is derived. An essential part of the heat is in the area of the embossings 87 from the coil 23 in the bracket element 39 derived. For how 6 As can be seen, there is a distance between the coil 23 and the stirrup element 39 minimal in this area, so that in this area a maximum thermal coupling of the coil 23 with the bracket element 39 results.

The illustrated embodiment of the quantity control valve device 11 has a plurality of predefined variants, wherein the individual predefined variants in the embodiment of the geometry of the plug-in section 25 differ. The following is based on the 8th a procedure 200. to Production of a quantity control valve device 11 described according to a particular of these variants. In this manufacturing process 200. is first in one step 201 a first tool part of the injection mold, which is used to produce the first section 31 and a first part of the transitional section 33 the plastic extrusion 29 is trained. In a subsequent step 203 is for each predefined variant, ie for each special shape of the plug-in section 25 , A second tool part for molding the male section 25 and a second part of the transition section 33 in the plastic extrusion 29 provided. The transition section 33 the plastic extrusion 29 This corresponds to a region within the entire encapsulation tool, on which the two tool parts adjoin one another. Because the flat surface 37 of the transitional section 33 has a larger surface area than the shadow area of the plug-in section 25 , The two tool parts can be provided with sealing surfaces for sealing the two tool parts against each other.

It then checks (step 205 ), whether the second tool part corresponding to the desired variant is attached to the first tool part and optionally (Y) to a step 209 branched. Otherwise (N), the second tool part, if it is attached to the first tool part, removed from the latter and the desired variant corresponding second tool part attached to the first tool part (step 207 ). After that, in one step 209 a plate-shaped development of the bracket element 39 from the metal plate 59 punched out and then the right angles curved sections 61 made by the settlement to the bracket element 39 is bent (step 211 ). Then in one step 213 the coil arrangement 24 within the temple element 39 arranged so that the stirrup element 39 the coil arrangement 24 on the opposite ends 41 embraces. In a final step 215 becomes the coil assembly 24 using the injection mold with the plastic extrusion 29 molded.

For sealing a space during the injection molding of the injection mold and the bracket element 39 is limited, the edge can 89 and / or the side surface 88 of the bracket element 39 be used, ie the Umspritzwerkzeug sitting during the Umspritzvorgangs on the inner edge 89 and / or the side surface 88 so that no liquid plastic between the injection mold and the inner edge 89 and / or the side surface 88 can flow through. Deviating from this can also be a method 200. be provided, only the steps 209 . 211 . 213 and 215 includes.
