Definitions

  • the invention relates to an intake pipe for an internal combustion engine with a safety valve which can be brought into the open position by a pressure in the interior which exceeds the atmospheric pressure, the safety valve consisting of a ring sleeve made of rubber-elastic material.
  • Such an intake pipe is known from EP 0 280 122 A2.
  • the intake pipe is equipped with a burst protection, which preferably has a separate opening of the intake system and an elastic, lip-like sealing element that cooperates in a biased manner with a limitation of the opening.
  • the lip-like sealing element is designed as a flap valve and, depending on the design, lifts off its sealing surface at a predetermined overpressure within the intake pipe.
  • Intake pipes for internal combustion engines are generally known and mostly consist of a metallic material or plastic.
  • the wall thickness of the previously known intake pipes is often dimensioned such that combustion pressures, which can return to the intake pipe if the internal combustion engine is incorrectly set, can be absorbed without damage. It should be noted, however, that the wall thicknesses of such intake pipes have a considerable thickness, which both in is less satisfactory in terms of production technology and in terms of economy and functionality. Thin-walled plastic intake pipes often cannot withstand the excess pressure and burst.
  • the invention has for its object to further develop an intake pipe of the type mentioned in such a way that the ring sleeve is held securely outside the cross section of the intake pipe when there is negative pressure in the intake pipe.
  • the ring sleeve sealingly encloses a wall opening of the intake pipe in the area of its outer diameter and a pin in the area of its inner diameter, that the ring sleeve is designed as a bellows, that the bellows and the pin each have an adapted surface profile and that the surface profiles can be sealingly engaged with one another when subjected to negative pressure.
  • the wall thicknesses of the intake pipe can be dimensioned to be comparatively thin-walled, since the excess pressure that can be present in the intake pipe is reduced via the safety valve.
  • Such an intake pipe has good performance characteristics over a long period of use, is simple and inexpensive to manufacture in terms of production technology, and has a low weight.
  • FIG. 2 also shows a section of an intake pipe, the ring collar being fixed on the intake pipe on the one hand and in the axial direction on the other hand on a vacuum connection which can be snapped into the wall opening of the intake pipe.
  • the bellows 9 is designed as a preassembled unit 10 with the vacuum port 8.
  • the outer diameter 5 of the bellows 9 is held captive in an undercut and is supported in the region of its inner diameter 7 on the vacuum connection 8.
  • the bellows 9 briefly lifts off the vacuum connection 8 until the overpressure is released from the intake pipe and a pressure equalization with the atmosphere is established.
  • the bellows 9 can be provided with reinforcement or stiffening ribs at least in the area of the wall opening 3 of the intake pipe 4.
  • the preassembled unit 10 can be attached to the suction pipe by friction welding / rotary welding or snapping.
