Definitions

  • the invention relates to a piston engine with the features of the preamble of claim 1, such as from the Document FR 2 779 681 A known.
  • a piston engine has an engine block with several cylinders and is equipped with a fresh gas supply, the several, assigned to the cylinders and on the engine block has specified feed pipes. About this fresh gas supply intake air or charge air is fed to the engine, which is needed for the combustion.
  • Modern piston engines are equipped with a fuel injection system that a high pressure supply line assigned to the cylinders having. In such a high pressure supply line the fuel under high pressure is common to the cylinders provided, using injectors a targeted metering of the fuel takes place.
  • Such one common high pressure supply line is generally referred to as "common rail".
  • the high pressure supply line is due to the high Fuel pressures are preferably made of metal.

  • Establishing the plastic Feed pipes on the engine block are usually made using Metal bushings that are in a flange section of the feed pipes be welded or melted to the feed pipes to be able to screw on the engine block.
  • the high pressure supply line can then directly on the engine block or attached to the feed pipes and thus indirectly to the engine block become. It is also possible to use the feed pipes and to manufacture the high-pressure supply line in one piece from metal, this integral assembly then using a appropriate screw on the engine block becomes.
  • the present invention addresses the problem to design a piston engine of the type mentioned at the beginning, that the attachment of the high pressure supply line and of the feed pipes simplified.
  • the invention is based on the general idea of the high-pressure supply line to design so that these with the Feed pipes cooperates in that the Attachment of the high pressure supply line at the same time Feed pipes to be fixed on the engine block.
  • This Measure can use additional fasteners for fixing the supply pipes on the engine block are not required.

  • the piston engine also has a fuel injection system, of which a high-pressure supply line 5 is shown here is the injection valves, not shown with connections 6 fueled. Because the fuel in the high pressure supply line 5 under a high working pressure stands, the high pressure supply line 5 is preferred in metal construction, in particular by a die casting process, manufactured.
  • a hold-down device 7 is formed for each feed pipe 1, which has a retaining ring 8.
  • Each of these retaining rings 8 is shaped so that the associated feed pipe 1 with an upper section 9 can be inserted therein and in an enlarged central section 10 comes into contact with it.
  • the inner contour of the retaining ring 8 expediently to the outer contour of the middle section 10 adapted so that there is a large area can form between the retaining ring 8 and the feed pipe 1.

Accordingly, the on Bearing section formed from the end facing away from the actuating lever 21 24 the smallest diameter, while the most formed end portion facing the actuating lever 28 has the largest diameter.
  • bearing openings not visible here trained to complement the bearing sections 24 to 28 are formed so that the drive shaft 19 coaxial to the dash-dotted line 20 in the Assembly of feed pipes 1, connecting webs 2, bearing approach 3 and carrier 4 can be introduced. It is clear that the bearing openings mentioned with regard to their So the diameter of the bearing portions 24th are tuned to 28 that the drive shaft 19th is pivotable and that on the other hand a sufficient Sealing between the individual feed pipes 1 guaranteed can be. Only in the position section 28, the end of the drive shaft having the actuating lever 21 19 is assigned, additional sealants be assigned. For example, this storage section contains 28 an annular groove 29 into which e.g. a 0-ring inserted can be. The bearing opening contained in bearing approach 3 is closed on one side for hermetic sealing formed so that the associated bearing portion 24th axially penetrates into this bearing opening.
