Definitions

  • the invention relates to a fuel distributor, which is used in particular for fuel injection systems of mixture-compressing, spark-ignited internal combustion engines. Specifically, the invention relates to the field of fuel injection systems designed as medium-pressure systems.
  • a fuel rail used for high pressure steel or aluminum applications may be used.
  • a compressive strength for pressures of, for example, 20 MPa (200 bar) can be achieved.
  • Such a high-pressure steel rail can be produced as a soldering rail.
  • a steel tube serves as a base to which the individual components, such as e.g. Caps, screw-on, a high pressure port and interfaces to the injection valve, so-called cups, are soldered.
  • this embodiment is associated with high production costs. Specifically, a drawn pipe must be cut to size. Furthermore, the ends must be processed and appropriate outlets drilled.
  • connection caps can be configured as turned or deep-drawn parts, while the connections can be configured as turned parts.
  • fuel rail assemblies may be used for low pressure applications at 0.3 MPa (3 bar) to 0.5 MPa (5 bar) for related applications.
  • the scope of such fuel rail for low pressure applications is limited to this low pressure range.
  • the mounting device comprises spring elements which each extend between each one of each fuel injection valve associated spring receptacle of the fuel rail and a spring receiving the associated fuel injection valve. Further, the mounting device comprises a mounting bracket common to all fuel injection valves, which extends from a mounting bracket receptacle of the fuel rail to the mounting bracket receptacle of the fuel injection valves. The spring elements clamp the fuel rail and the fuel injectors against each other so that the fuel rail and fuel injectors are held in frictional engagement with their associated mounting bracket receptacles and the mounting bracket is releasable and removable upon compression of the spring members.
  • the fuel distributor according to the invention with the features of claim 1 has the advantage that a fuel distributor with comparatively low production costs can be created, which may be suitable in particular for a medium pressure.
  • the fuel distributor can be designed particularly low by the individual components, in particular the valve cups, are attached with an advantageous connection technology to a distributor to be produced inexpensively. As a result, the fuel distributor can be produced inexpensively while achieving the desired strength and pressure resistance.
  • the secure connection of the juxtaposed items under operating conditions and the attachment of the fuel distributor to an engine block or the like can be done via the clamping part.
  • the clamping part may in this case be formed in an advantageous manner as a punched and bent part.
  • the clamping part can be configured in an advantageous manner as a clamping plate. Such a clamping plate secures over the bias of the elastic deformation of the geometry of the secure connection of the assembled items. In this case, a simple assembly technique can be used, in which the items are arranged on the manifold and then fixed on the clamping part to the manifold.
  • the distributor piece is formed from at least one plastic.
  • the valve cups are formed from at least one plastic and optionally as an injection molded part.
  • the manifold can be designed as a tubular manifold, that is, as a manifold.
  • Such a tubular distributor piece can be designed, for example, as a thick-walled plastic tube produced by the extrusion method. In order to achieve a sufficient compressive strength, in this case preferably several fabric layers with different winding angles are incorporated. This thick-walled plastic pipe is deflected to the desired length and provided with mounting holes for the valve cups.
  • the manifold can be made particularly inexpensive and easily adapted to the particular application, in particular the desired pressure range.
  • the clamping part can be formed in an advantageous manner from a non-alloy steel sheet. As corrosion protection here is optionally a surface coating of Steel sheet possible. Thus, the clamping part can be made particularly inexpensive. The clamping part then secures the joined assembly parts at operating pressure and allows the attachment of the fuel distributor on the engine block or the like.
  • valve cups each have a hollow mandrel which is inserted into a provided for the respective valve cup bore of the manifold.
  • a sealing ring is provided for each valve cup, which bears against an outer side of the manifold and the hollow mandrel of the respective valve cup surrounds, and that due to the bias of the clamping part of the sealing ring between the outside of the manifold and the respective valve cup a bias voltage is applied.
  • the bias of the sealing ring is not necessarily equal to the bias that exerts the clamping part on the valve cup.
  • an annular receiving groove may be provided on the valve cup, in which the sealing ring is at least partially inserted in order to limit compression of the sealing ring and thus the bias of the sealing ring.
  • a defined pretensioning of the sealing ring is made possible so that an overstress is avoided and the sealing effect can be maintained over the service life.
  • the bias of the clamping member initially that is, during assembly, then be set correspondingly large, so that even with decreasing over time bias of the clamping part, the required for the sealing ring bias is still guaranteed.
  • the sealing effect between the individual valve cups and the manifold can be chosen so large that the required operating pressure can be reliably achieved.
  • a corresponding configuration, in particular with regard to the hollow mandrel and / or the sealing ring can also be used in other attachments, in particular a closure plug and a connection piece.
  • valve cups each have a channel which extends from the respective hollow mandrel to a valve receptacle and that the channel is angled at least approximately 90 °. This results in a space-saving design in which in particular a distance between the manifold and an engine block can be optimized.
  • an end plug is provided, which closes a tubular ausgestaltetes manifold at one end, and that the clamping member biases the end plug against the tubular manifold with a bias.
  • the end plug can also be fixed on the clamping piece on the manifold.
