Definitions
- the invention is based on a valve for metering a flowing medium, in particular an injection valve for fuel injection systems of internal combustion engines, according to the preamble of claim 1.
- a known, designed as a so-called multi-hole valve fuel injection valve for fuel injection systems of internal combustion engines (DE 10 2005 036 951 A1) has a hollow cylindrical valve seat support end valve seat body in which a plurality of spray holes with Lochein- and Lochautrittsö réelleen are arranged so that the hole inlet openings in the inner body wall and the hole outlet openings in the outer body wall of the valve seat body each lie on a divider circle.
- a valve seat in the form of a concentric with the valve seat body axis annular surface is formed, which encloses all hole inlet openings.
- the valve seat together with a closing head, forms one by means of an actuator, e.g.
- Electromagnet, driven valve member a the intake ports closing upstream upstream sealing seat.
- a guide body for the closing head is arranged, which has axially continuous fürströmumgskanäle and abuts the end face on the inner body wall of the valve seat.
- a valve chamber is formed in the valve seat carrier, which communicates via fuel supply channels with a fuel flow, so that fuel under system pressure is present at the sealing seat.
- the metering valve according to the invention with the features of claim 1 has the advantage that is uniformed by the arranged between the sealing seat and spray holes Anströmformer with at least one passage opening even if the number of passage channels on the one hand and spray holes on the other hand, the flow of the injection holes through the medium.
- the Anströmformer is formed as a flat Anströmular. This makes it possible to arrange the Anströmformer in the space within the valve greatly limited space between the sealing seat and hole inlet openings of the injection holes.
- the height of the Anströmusion can be kept very low, since it is structurally not charged and must absorb only the resulting from the pressure drop forces.
- a single flow opening is arranged as a circular central hole in the disk center in the Anströmusion. Through the central hole, the hole inlet openings of the injection holes are uniformly from the valve center, ie from the direction of the valve axis, flowing, so that the flow is largely unified.
- a plurality of throughflow openings are present in the inflow disk, which are designed as radially extending slots and aligned in a star shape in the inflow disk and whose number corresponds to the number of injection ports.
- Anströmformer is used when the hole inlet openings of the injection holes to be flowed laterally.
- a plurality of flow openings exist, which are formed as a circular, preferably small holes, so that there is a Lochsieb- structure of the Anströmular.
- the injection holes are arranged in a valve seat having the valve seat body, which closes a hollow cylindrical valve seat carrier.
- the valve seat carrier associated with a medium inlet valve chamber is formed, and the
- Flow channels are open to the valve chamber.
- the flow channels are formed in a hollow cylindrical guide neck of the valve seat body, which projects into the valve seat carrier, wherein the flow channels are formed as incorporated into the cylinder wall of the guide stub Axialnuten pointing into the nozzle interior groove opening.
- FIG. 1 shows a detail of a partial longitudinal section of a valve for a flowing medium
- FIG. 2 shows a section along the line II-II in FIG. 1
- FIG. 3 is an enlarged view of section III in FIG. 1,
- FIG. 4 shows a plan view of a flow-through former in the valve of FIG. 1,
- Figure 5 is a same view as in Figure 4 of another embodiment of a Anströmformers.
- Injection valve designed for fuel injection systems of internal combustion engines for injecting fuel into a combustion cylinder or in an air intake pipe of the internal combustion engine.
- the valve has a sleeve-shaped valve seat carrier 1 1, which protrudes from a valve housing, not shown here, and is closed off at its free end with a valve seat body 12.
- the valve seat body 12 is located with a radial flange 121 close to the annular end face of the valve seat carrier 1 1 and protrudes with a hollow cylindrical guide piece 122 form fit into the valve seat carrier 1 1 inside.
- the guide sleeve 122 has guide surfaces 27 ( Figure 2) for a closing head 13 of an axially slidably received in the valve seat carrier 1 1 valve member 14 which is driven by means of an actuator, not shown, for example, an electromagnet, to lift movements.
- the closing head 13 forms a sealing seat 16 with a valve seat 15 formed on the valve seat body 12.
- a valve chamber 17 located upstream of the sealing seat 16 communicates with a medium inlet, not shown here, in the valve housing, so that under system pressure medium, in the case of the injector so fuel is present at the sealing seat 16.
- the multi-hole valve designed valve has a plurality of injection holes 18 with hole inlet openings 181, which are arranged downstream of the sealing seat 16.
- the injection holes 18 are formed with valve axes inclined to the valve axis in the valve seat body 12 so that lying in the inner body wall of the valve seat body 12, spaced apart hole inlet openings 181 on a first so-called.
- Divisor circle so have the same distance in the circumferential direction of the circle ,
- Flow channels 19 in the circumferential direction of the circle are in turn the same size.
- the second so-called divider circle has a significantly larger diameter than the first divider circle for the hole inlet openings 181.
- the flow-through channels 19 are arranged in the cylinder wall of the guide neck 122 of the valve seat body 12 and formed as in the cylinder wall of the guide neck 122 incorporated axial grooves 20 with between the guide surfaces 27 extending groove openings.
- a total of five flow-through channels 19, that is to say five axial grooves 20, are present in the guide neck 122 as the optimum number of throughflow channels 19.
- the valve seat body 12 has a total of six injection holes 18, of which only two can be seen in the sectional view of FIG.
- Anströmvektoren to achieve is between the sealing seat 16 and the hole inlet openings 181 of Spray holes 18 a Anströmformer 21 arranged, which has at least one flow opening 22. Because of the very limited installation space in the valve seat body 12 between the valve seat 15 and hole inlet openings 181 is the
- Anströmformer 21 formed as a flat Anströmarea 23 which in the valve seat body 12 is fixed to a lying between the valve seat 15 and hole inlet openings 181 wall portion of the valve seat body 12.
- the flow disk 23 to be seen in section in FIG. 1 and in the enlarged view of FIG. 3 has a single flow opening 22, which is arranged as a circular central hole 26 in the center of the disk.
- Figure 4 and Figure 5 show two further variants of the Anströmular 23 in plan view.
- a plurality of flow openings 22 are provided, which are formed as radially extending slots 24 and aligned in a star shape in the Anströmular 23.
- the number of slots 24 corresponds to the number of spray holes 18, so in the embodiment, six.
- This Anströmectomy 23 is then used, if it is advantageous, the hole inlet openings 181 of the injection holes 18 flow laterally.
- the flow-through openings 22 are formed as preferably small holes 25 and circular, so that the Anströmular 23 has the structure of a perforated screen. Through this large number of small holes a perfectly uniform flow of the hole inlet openings 181 is achieved.
- each gaseous and liquid medium can be sprayed metered with the valve, in which a spray treatment of ist sprayten amount of medium to be achieved.
- the valve can be used for injecting a urea-water solution into the exhaust gas tract of the internal combustion engine in order to achieve a reduction of nitrogen oxides in the exhaust gas.
