Definitions
- the invention relates to a fuel injector according to the preamble of claim 1 and a method for assembling a fuel injector in a valve holder according to the preamble of claim 10.
- DE 28 27 789 AI known to provide two sealing rings on a stepped inlet connection of the fuel injector. These can be designed, for example, as whole ring assemblies, which then have a stuffing box ring, an O-ring, an asbestos ring and an unsmelted melting ring directly in succession.
- fuel injection valves are already known, the sealing of which is carried out by means of sealing packets, with additional rings with so-called so-called O-shaped rings
- a fuel injection system is known from DE 197 35 665 AI, in which a fuel injection valve by means of an intermediate piece with a valve receptacle
- Fuel supply line is connected and sealed against it.
- both the inlet connector of the fuel injection valve and the intermediate piece each have a sealing ring on their outer circumference, which are thus spatially clearly separated from one another.
- the fuel injector according to the invention with the characterizing features of claim 1 has the advantage that a sealing arrangement with two sealing rings is provided on its outer circumference, which is particularly easy to install, which avoids overstretching and over-expansion of the sealing rings and thus in principle damage to the sealing rings, which nevertheless Sufficiently large support shoulders for the sealing rings are guaranteed and, due to the increasingly stringent environmental requirements, completely prevents the release of hydrocarbons into the environment.
- Advantageous further developments and improvements of the fuel injector specified in claim 1 are possible through the measures listed in the subclaims.
- the particularly simple handling of the two subcomponents of the intermediate ring is advantageous. While the inner support ring with an inwardly projecting nose can be mounted very easily in a groove on the inlet connector of the fuel injector, the outer ring can be easily and securely locked onto the support ring.
- the latching bead on the support ring which is used for latching is advantageously designed in such a way that the high compression forces of the one sealing ring are absorbed by an upper horizontal latching surface when the fuel injector is installed in the receiving connector.
- the lower axial dismantling forces of the other sealing ring are sufficiently absorbed by a lower, obliquely designed locking surface of the locking bead.
- the method according to the invention for assembling a fuel injection valve in a valve holder with the characterizing features of claim 10 has the advantage that the entire assembly can be carried out fully automatically.
- the sealing rings are treated very gently during assembly, which is why damage to the sealing rings is excluded. It is particularly advantageous that the sealing rings hardly have to be spread apart despite being brought into annular chambers that are separate from one another and therefore do not have to be dangerously overstretched.
- the two-part design of the intermediate ring ensures that the first sealing ring can be installed without overstretching and that there are sufficient support shoulders for both sealing rings.
- FIG. 1 shows an inlet end of a fuel injection valve with a sealing arrangement according to the invention for sealing the fuel injection valve with respect to a valve seat
- FIG. 2 shows an enlargement of section II in FIG. 1.
- a fuel injector 1 which is designed, for example, as an injection valve for injecting fuel directly into the combustion chamber of a mixture-compressing, spark-ignition internal combustion engine. With an inlet end 2, the fuel injection valve 1 projects into a corresponding valve seat 3.
- the valve receptacle 3 is, for example, as a cup-shaped
- Recording port 4 formed, the part of a fuel not shown supply, eg. B. of a fuel rail.
- the fuel supply line usually has a plurality of receptacles 4, so that the fuel supplied via the fuel supply line can be distributed to a plurality of fuel injection valves 1.
- the recording clip 4 is z. B. executed step-like and has at its end facing away from the fuel supply line one or more protruding fastening elements 5.
- This loading elements 5 engage in openings 6 of a mounting bracket 7, which is used to reliably secure the fuel fine injection valve 1 in the valve seat 3.
- the mounting bracket 7 is, for example, in a circumferential groove 8 on the outer circumference of a plastic injection molding 9 of the
- Fuel injector 1 used.
- the fuel injection valve 1 is largely surrounded by the plastic encapsulation 9.
- a metal inlet connection 11 which serves to supply fuel to the interior of the fuel injection valve 1, protrudes from the plastic extrusion coating 9.
- two sealing rings 13, 14 designed as O-rings are arranged on the outer circumference of the inlet connector 11.
- the two sealing rings 13, 14, which follow one another axially close, are spatially spaced apart from one another by an intermediate ring 15 designed according to the invention.
- the upstream end of the fuel injection valve 1 is formed by an upper securing ring 16 which is applied to the inlet connection 11
- the two sealing rings 13, 14 are two "full-fledged" sealing rings made of known elastomer sealing material
- hydrocarbons can permeate through the elastomers commonly used for sealing rings and can fully enforce them.
- the intermediate ring 15, which divides the sealing space into two annular chambers 18, 19, consists of two subcomponents.
- An inner support ring 22 engages, for example, in a circumferential groove 23 on the circumference of the inlet connector 11. In i ⁇ lealer manner, the support ring 22 is simultaneously with the
- the support ring 22 On its inside, the support ring 22 has an inwardly projecting, bevelled nose 24 which can be inserted into the groove 23 with a precise shape.
- the area of the locking bead 25 is shown enlarged in FIG. 2.
- the locking bead 25 on the support ring 22 is designed such that the high compression forces of the second sealing ring 13 are absorbed by an upper locking surface 28 which is largely perpendicular to a longitudinal valve axis 30 when the fuel injector 1 is mounted in the receiving connector 4.
- the lower axial disassembly forces of the first sealing ring 14 are sufficiently absorbed by a lower, obliquely designed locking surface 29 of the locking bead 25.
- the outer ring 26 consists of a flexible plastic. When the outer ring 26 is mounted on the inner support ring 22, this plastic expands and then engages in the end position over the locking bead 25.
- the intermediate ring 15 consisting of the outer ring 26 and the support ring 22 serves as a support shoulder for the second sealing ring 13.
- the assembly of the sealing arrangement on the inlet connection 11 of the fuel injection valve 1 is briefly explained below.
- the invention is not restricted to the exemplary embodiment shown. So it is also conceivable, e.g. to design the inlet connection 11 in the area of the sealing rings 13, 14 in a stepped manner and / or to use sealing rings 13, 14 with different cross sections or diameters.
