Definitions

  • the invention relates to a valve for metering a fluid, in particular a fuel injection valve for internal combustion engines.
  • the invention relates to the field of injectors for fuel injection systems of motor vehicles, in which there is preferably a direct injection of fuel into combustion chambers of an internal combustion engine.
  • the invention relates to an arrangement with a valve and a fastening body, in particular a cylinder head, wherein the valve is preferably used for gasoline direct injection.
  • This fuel injection valve has a tubular valve seat carrier, which is insertable into a receiving bore of a cylinder head of an internal combustion engine and is sealed against a receiving bore of the cylinder head by means of a seal.
  • valve for metering a fluid, in particular a fuel injection valve for internal combustion engines, and a fastening body, in particular a cylinder head.
  • the valve has a valve housing, wherein an outer surface is configured on a joining portion of the valve housing and wherein a locking means in the form of locking lugs is arranged at a location on the edge of the outer surface of the joining portion, the permanent or at least in a serving for locking state radially over the Outer surface protrudes.
  • a mounting hole is formed, wherein the locking means of the valve acts in a mounted state of the valve so with a groove together that a rotation for the valve is formed.
  • the locking device is provided at the inflow end of the valve above the cylinder head near a fixing claw.
  • a spring acted locking mechanism can be provided, which has a spring element and a configured as a ball detent body.
  • the locking body can engage in a recess of the inner cylinder.
  • the arrangement according to the invention with the features of claim 1 has the advantage that an improved design and operation are possible.
  • an exhaust gas composition can be positively influenced.
  • valve is mounted in a suitable manner, wherein the valve housing is inserted at its joining portion in a mounting hole.
  • a correspondingly adapted embodiment of the mounting hole is realized to allow the assembly of the valve.
  • One possible advantage is an improved exhaust gas composition.
  • soot particle emissions are increasingly becoming the focus of combustion process development.
  • gasoline direct injection valves are currently working on a variety of topics, such as increasing jet accuracy and stability, and reducing penetration, injection timing, and wetting of the valve seat tip.
  • the aim of such measures is the most even fuel distribution in the combustion chamber and avoid surfaces wetted with fuel, which is relevant both in the combustion chamber and at the injector, at the time of ignition. Fuel wetted surfaces are considered to be major sources of soot in gasoline direct injection engines.
  • a relevant development trend also consists in the reduction of the displacement, which leads in addition to increased requirements with regard to the accuracy of the injection, in particular with regard to the injection pattern. Consequently, it is advantageous that the injection jet realized by the injector and especially its injection pattern are adapted as well as possible to the respective engine geometry and the flow conditions in the combustion chamber.
  • a conceivable possibility for orientation of an injector in the cylinder head consists in a molded plastic nose, which projects either into a cylinder head mounted groove or in a groove on a rail cup to achieve Vermosfix ist. Since such molded plastic noses are thin and pliable, so that they alone can not align the injector, the VerFfix isten have manufacturing and assembly reasons in the respective groove a relatively large game, resulting in relatively large possible twist angles.
  • the entire arithmetic tolerance chain with respect to the alignment accuracy of the injection holes of the injector with respect to the cylinder head to take into account, for example, from the positioning accuracy of the rail cup over the cylinder head, the positioning accuracy Verwarfix ist against the rail cup, in particular the game in the groove, the positioning accuracy of the valve seat with respect to the injector and the accuracy of the jet pattern relative to the valve seat together.
  • the injector is aligned directly opposite a groove mounted in the cylinder head.
  • the tolerance calculation performed above is thereby reduced to the positioning accuracy of the valve seat relative to the cylinder head, which is done by the latching, and the accuracy of the jet pattern relative to the valve seat.
  • the tolerance with respect to the positioning accuracy of the jet pattern relative to the cylinder head can be considerably reduced.
  • valve seat which are otherwise required for aligning the seat with respect to the injector, because a bore in the valve housing or the like or the Ausrichtnase or the like can be used directly as a reference for the drilling of the injection holes.
  • the design possibilities proposed in claim 2 have the advantage that after the axial insertion of the valve with its joining portion in the mounting hole a rotation is made possible, wherein the locking means engages in the groove on the mounting hole when the locking means is movable.
  • a gap between the outer surface of the valve housing and the mounting hole can be made as small as possible in the assembled state.
  • the embodiment according to claim 3 has the advantage that a latching mechanism can be realized.
  • an axial joining can first take place according to which the locking element is located on a specific side of the associated groove in the fastening bore.
  • the direction of rotation is then defined, in which over a short rotation angle, a locking of the locking element can be made in the groove.
  • the groove can be realized in this case with a limited coaxial expansion, which simplifies, inter alia, a seal.
  • a sealing element or the like must otherwise seal the region of the groove when the locking means is arranged seen from the seal in the joining direction.
  • the locking means is at least largely, that is largely or completely, movable in the radial direction. Especially in the case of a cylindrical jacket-shaped configuration of the outer surface, an optimum movement path in the radial direction can be achieved.
  • the spring element is at least largely, in particular completely, acted upon in the radial direction. As a result, a large latching force can be achieved in relation to the spring element.
  • the embodiment according to claim 5 has the advantage that the lock can be realized against rotation without significant structural changes in a valve.
  • the outer surface, arranged in or at the edge of the locking means may be only part of the outside of the valve housing to which the captive can be attached, as proposed according to claim 7.
  • an assembly can be used for the realization, which comprises for example a sheet metal sleeve, a spring element and the locking element.
  • the edge of the sleeve can be configured for example by crimping as flanged end stop, which forms the captive for the locking element.
  • Such a sleeve or the locking element itself can be added according to claim 9 in a recess of the valve housing or arranged in the recess of the valve housing.
  • the specified in claim 10 advantageous embodiments of the locking allow in relation to the particular application, an advantageous assembly and locking and optionally also an advantageous disassembly.
