Definitions

  • Valves for example for gas channels
  • They are known. They often consist of a housing with a valve seat, in which a rotatably arranged flap for closing the gas channel is arranged.
  • the flap is provided with an external piston seal.
  • This usually consists of a metal ring that has a gap for reasons of flexibility. In operation, it is often disadvantageous that leakage air can pass through this gap, which is not desirable. This is particularly the case when the gases to be conducted through the valve have relatively high temperatures and additionally fluctuate greatly in their temperatures.
  • the invention is therefore based on the object of providing a valve in which the formation of leakage air can be largely avoided.
  • a secure closing of the gas channel should thus be largely ensured even at higher and fluctuating gas temperatures.
  • a valve which consists of a housing with a valve seat for a flap which is rotatably mounted on a drive shaft, in which a double-wound lamellar ring is arranged around the flap in a circumferential groove of the flap ,
  • the double-wound lamellar ring is a flat metal ring that is double-wound and thus has almost the shape of a simple key fob.
  • the valve seat can also be part of the housing, for example. It has surprisingly been found that the arrangement of the double-wound lamellar ring as Piston seal the formation of leakage air can be largely avoided.
  • the flexibility of the double-wound lamellar ring is given such that the valve can be securely closed even at higher and fluctuating temperatures of the gas. Since the arrangement of a gap is dispensed with, it is advantageously avoided that leakage air can get from one side of the flap to the other side of the flap.
  • the valve seat is designed as a steel ring which is pressed into the housing. This can significantly increase the wear resistance in the valve seat. This is particularly advantageous if the valve is often to be opened and closed.
  • an aluminum housing is arranged.
  • the valve thus has a lower weight, while at the same time ensuring high wear resistance in the valve seat.
  • the invention relates to the use of the valve as a gas recirculation valve of a motor vehicle.
  • Gases that are passed through a gas recirculation valve of a motor vehicle generally have high temperatures and large temperature fluctuations. In this case, the formation of leakage air is completely undesirable.
  • the use of the valve according to the invention as a gas recirculation valve of a motor vehicle is therefore particularly advantageous.
  • Fig. 1 shows the valve in cross section.
  • Fig. 2 shows a three-dimensional representation of the double-wound lamellar ring.
  • the valve is shown in cross section.
  • the valve consists of a housing 3 with a valve seat 4 for a flap 2 which is rotatably mounted on a drive shaft 1.
  • a double-wound lamellar ring 5 is arranged on the outside of the flap 2 in a circumferential groove in the flap 2.
  • the valve seat 4 is designed as a steel ring which is pressed into the housing 3. This has an advantageous effect on the wear resistance of the valve seat 4.
  • the housing 3, however, is made of aluminum, which has an advantageous effect on the weight of the valve.
  • the valve is particularly suitable as a gas recirculation valve of a motor vehicle.
  • the double-wound lamellar ring 5 is shown three-dimensionally. It has the shape of a simple key ring.
