Definitions
- the invention relates to a nozzle assembly for a fuel! Injector for injecting fuel into the combustion chamber of an internal combustion engine having the features of the preamble of claim 1. Furthermore, the invention relates to a fuel injector with such a nozzle assembly.
- German Offenlegungsschrift DE 10 2008 039 920 A1 discloses a nozzle assembly for a fuel injector, comprising a nozzle body having a bore which opens into a blind hole via a conical nozzle needle seat for a conical sealing surface of a nozzle needle received in the bore. In the area of the blind hole several injection openings are arranged in a row of holes.
- the nozzle needle has a nozzle needle tip with a pin which dips into the blind hole and in this way reduces the dead volume remaining in the blind hole in the closed position of the nozzle needle.
- the peg-like nozzle needle tip can be lifted completely out of the blind hole, so that there is a risk of the nozzle needle striking the nozzle body during re-immersion.
- the result is increased wear in the transition region from the nozzle needle seat into the blind hole, in particular in the area of an intersecting edge. The wear in turn leads to a changed switching behavior of the nozzle needle.
- a nozzle assembly for a fuel! Njektor comprising a nozzle needle with a dive into a blind hole pin indicate that is less prone to wear.
- the proposed nozzle assembly comprises a nozzle body and a nozzle needle, which is accommodated for releasing and closing at least one injection port in a high-pressure bore of the nozzle body, wherein a in a blind hole-like end portion overflowing conical portion of the high-pressure bore for forming a valve seat with a conical sealing surface of the nozzle needle to which is a plunged into the blind hole-like end portion pin is attached, sealingly cooperates.
- a valve seat near guide portion upstream of the valve seat between the nozzle needle and the nozzle body is formed for permanent guidance of the nozzle needle in the high pressure bore, whose radial guide clearance smaller than a radial gap between a cylindrical portion of the blind hole-like end portion of the high pressure bore and a cylindrical portion of the pin of the nozzle needle for training is a stroke-dependent throttle.
- the permanent guidance of the nozzle needle via the at least one valve seat near the guide region upstream of the valve seat prevents a radial deflection of the nozzle needle and thus the risk of striking the nozzle needle on the nozzle body. In this way, the wear in the transition region from the valve seat in the blind hole-like end portion is significantly reduced.
- the pin of the nozzle needle can be formed such that it a cylindrical part of the blind hole-like end portion cooperating throttle forming.
- the throttle formation is dependent on the stroke of the nozzle needle, so that over this the inflow to at least one injection port is controllable.
- the radial gap is greater than the radial guide clearance of the valve seat near the guide region upstream of the valve seat selected. Because the radial gap is not suitable for permanent guidance of the nozzle needle in the high-pressure bore, since its formation is dependent on the stroke of the nozzle needle. Accordingly, a radial function could only temporarily take over a radial gap.
- valve seat near guide region is not opposed, that at an axial distance thereto, d. H. in a valve seat remote region of the high-pressure bore, a further guide region for permanent guidance of the nozzle needle is formed, as is common in known nozzle assemblies for fuel!
- the injectors are the case.
- a further valve seat remote guide region upstream of the valve seat the leadership of the nozzle needle can be further optimized.
- the permanent guidance of the nozzle needle via the at least one valve seat near guide region not only has a wear-reducing effect, but also prevents an asymmetrical spray pattern caused by a disalignment of the nozzle needle. This affects the use of the nozzle assembly in a fuel! Njektor for injecting fuel into a combustion chamber of an internal combustion engine advantageous to the pollutant emissions of the internal combustion engine.
- the nozzle body or the nozzle needle to form the valve seat near the guide region upstream of the valve seat at least two axially extending guide ribs, between which flow channels are formed.
- the flow channels provide the inflow of fuel to the at least one injection port during operation of the fuel! safe.
- the guide ribs are formed on the nozzle body, they preferably cooperate with a cylindrical shaft section of the nozzle needle in a gap-forming manner.
- the guide ribs are preferably formed on a cylindrical wall surface of the nozzle which radially delimits the high-pressure bore. arranged sen emotionss and protrude into the high pressure bore.
- the guide ribs may be formed on the nozzle needle and cooperate with a high pressure bore radially bounding cylindrical wall surface of the nozzle body gap-forming.
- the guide ribs can be arranged in this case on a cylindrical shaft portion of the nozzle needle, so that they protrude into the high-pressure bore.
- the axially extending guide ribs for forming the valve seat near guide region upstream of the valve seat are arranged at the same angular distance from each other.
- at least three guide ribs are provided at a distance of 120 ° from each other.
- the angular distance is 90 °, with five guide ribs 72 ° and with six guide ribs 60 °.
- more than six guide ribs can be provided, wherein it must be ensured that sufficiently large flow channels remain between the guide ribs.
- the same angular distance of the guide ribs to each other ensures optimal guidance of the nozzle needle in the high-pressure bore.
- a radial gap of less than 20 ⁇ , preferably less than 10 ⁇ is proposed.
- the leadership function of the valve seat near guide area is maintained, its radial guide clearance is to be chosen correspondingly smaller.
- a plurality of injection openings are provided for forming at least one spray hole row.
- the plurality of injection openings of a spray hole row are preferably arranged at the same Wnkelabstand to each other to produce a symmetrical spray pattern. It is also proposed that at least two injection openings are provided, which are arranged at an axial distance from one another. This allows the formation of at least two axially spaced spray hole rows.
- the arrangement of the axially spaced injection openings is preferably carried out in such a way that the inflow of fuel through the throttle-forming Radi as a gap in dependence on the stroke of the nozzle needle is controllable.
- the at least two axially spaced injection openings for example, such are arranged so that at least one injection opening in the region of the blind-hole-like end portion and at least one further injection opening in the region of the conical portion downstream of the valve seat open into the high-pressure bore.
- the at least one injection opening opening into the blind-hole-like end section is then controllable via the throttle-forming radial gap.
- a fuel injector is proposed with a nozzle assembly according to the invention further.
- the less-prone nozzle assembly increases the life of the fuel injector.
- the pollutant emissions can also be reduced since the permanent guidance prevents a radial deflection of the nozzle needle and thus an asymmetrical spray pattern.
- the fuel injector may in particular be a fuel injector for a common rail injection system.
- FIG. 1 shows a longitudinal section through a nozzle assembly according to the invention in the region of a valve seat.
- the nozzle assembly shown comprises a nozzle body 1 with a high-pressure bore 4, in which a nozzle needle 2 is received in a liftable manner.
- the high-pressure bore 4 has, to form a valve seat 7, a conical section 6, which merges into a blind-hole-like end section 5, into which at least one injection opening 3 opens.
- a further injection opening 3 opens into the conical section 5 into the high-pressure bore 4.
- the nozzle needle 2 has a conical sealing surface 8 sealingly cooperating with the valve seat 7, on which che a pin 9 is attached.
- the pin 9 has a directly adjacent to the conical sealing surface 8 cylindrical part which cooperates with a cylindrical portion of the blind hole-like end portion 5 - in response to the stroke of the nozzle needle 2 - forming a radial gap 11.
- the radial gap 11 has a throttle function to control the inflow of fuel to the injection port 3, which opens into the blind-hole-like end portion 5 of the high-pressure bore 4. This has the consequence that in a first phase of the opening stroke of the nozzle needle 2, the injection takes place primarily via the injection port 3, which opens into the conical portion 6 of the high-pressure bore 4.
- the nozzle assembly shown has a valve seat near guide portion 10 upstream of the valve seat 7.
- the guide region 10 is formed by a plurality of axially extending guide ribs 12 of the nozzle body 1, which cooperate with a cylindrical shaft portion of the nozzle needle 2 forming a gap.
- the guide ribs 12 protrude from a cylindrical wall surface of the nozzle body 1 to the radial boundary of the high-pressure bore 4 into the high-pressure bore 4.
- the guide ribs 12 are provided at an angular distance of 90 °, wherein between the guide ribs 12 axially extending flow channels are formed, which ensure the inflow of fuel to the injection openings 3.
- the guide region 10 ensures a permanent guidance of the nozzle needle 2 in the high-pressure bore 4 independently of the stroke of the nozzle needle 2. This ensures that the nozzle needle 2 undergoes no radial deflection, which could lead to the striking of the pin 9 on the nozzle body 1.
- the Radial gap 11 greater than the radial guide clearance of the valve seat near the guide region 10 is selected.
- a further advantage of the permanent guidance of the nozzle needle 2 via the guide region 10 which is close to the valve seat can be seen in the fact that an asymmetrical spray pattern associated with a dehiscence of the nozzle needle 2 is prevented.
- This has a favorable effect on the pollutant emissions when using the nozzle assembly in a fuel injector for injecting fuel into the combustion chamber of an internal combustion engine. This means that pollutant emissions are reduced.
- the invention is not limited to the illustrated preferred embodiment. Modifications are possible, which relate in particular to the number, arrangement and specific design of the guide ribs 12 for forming the guide region 10.
- the guide ribs 12 may also be formed on the nozzle needle 2.
- the number, the arrangement and the specific configuration of preferably a plurality of injection openings 3 are freely selectable.
