Definitions

  • the invention relates to a thin-walled intake manifold for an internal combustion engine according to the preamble of claim 1.
  • suction pipes are increasingly used because they are considerably lighter are as thin-walled suction pipes and in terms of their surface and shape can be designed more freely. They are made of metal or plastic, both of which lack strength
  • the invention is therefore based on the object of a generic To design the intake manifold so that the lack of strength compensates and the bursting of the thin-walled suction pipe is excluded.
  • the drawing shows a section through a section 1 of a downstream Throttle valve seat, not shown, lying plastic / metal suction pipe, that leads to one of the cylinders of the internal combustion engine.
  • this intake manifold is provided downstream of the throttle valve connector to arrange an opening 2 leading into the atmosphere, which through a valve 3 responsive to the pressure in the intake manifold 1 is controlled.
  • This valve 3 is a so-called elastomer umbrella valve 4, which projects into a central opening 6 with a stem 5 and is held by a stud 7 of a screw bushing 8.
  • the screw bushing 8 has a collar ring 10 spaced apart by ribs 9 on which a cover cap 11 is pushed and clipped to it, the ribs 9 of the screw bushing 8 form a tool attachment 12, so that the screw bushing 8 can be screwed into the opening 2.
  • the invention is based on the knowledge that the bursting of the suction pipes 1 due to an explosion-like occurrence that occurs occasionally after the engine is started Ignition of stored / condensed and in the intake manifold 1 mixed with the air contained in the intake manifold 1 fuel / fuel vapor residues is caused.
  • this pressure increase is caused by opening of the valve 3 limited.
  • the air / fuel gas can be released into the free atmosphere emerge.
  • the burning one cools in the opening 2 divided by ribs 13 Gas from and also in the outlet opening covered by the cap 11 13 between screw bushing 8 and collar ring 10. Then closes valve 3 again, the internal combustion engine remains ready for operation.
  • the cover cap 11 prevents dirt and water from entering the opening 2.
