Definitions

  • the invention relates to a device for connecting a corrugated tube to a counterpart.
  • Corrugated pipes have the advantage over smooth pipes and hoses that they also follow strong bends without kinks and closures occurring. This property makes corrugated pipes interesting for many technical applications, for example in mechanical engineering and in motor vehicles. Corrugated pipes are suitable for the transport of liquids such as windshield wiper liquid or hydraulic oil. Corrugated pipes are also suitable for guiding cables and light guides.
  • the corrugated tube has a preferably cylindrical body which extends in the axial direction and comprises wave crests and wave troughs running in the circumferential direction. At least some of these wave crests and / or wave troughs have circumferential sealing structures which rise radially out of the contour of the wave crests and / or wave troughs, namely radially outwards or inwards.
  • the connection arrangement which is provided for the fluid-tight connection of the corrugated tube to a counterpart, has one with the counterpart. piece firmly connected corrugated pipe connection section and a device connection section.
  • the corrugated pipe connection section comprises an inner support sleeve and / or an outer connection sleeve.

  • the opening lever specified in claim 6 facilitate releasing the sleeve from the casing.
  • a particularly compact, space-saving connection of the corrugated pipe to the counterpart is achieved by the features specified in claim 7. This is particularly advantageous when the device is used in a motor vehicle, since there are narrow installation conditions.
  • the device is designed as specified in claim 8, then the accuracy requirements for the end face of the corrugated tube are reduced. For example, it can run slightly obliquely.
  • the conical design of the sheath and sleeve, as specified in claim 9, further facilitates the joining of the connection device.
  • the advantages of a device with the features specified in claim 10 are that the tightness of the connecting device is also improved in the area of the counterpart.

  • One end area of the corrugated pipe is connected to a connection piece provided on the liquid container and realized in the form of a nipple
  • the other end area of the corrugated pipe is connected to a connection piece provided on the spray nozzle device and realized in the form of a nipple.
  • connections must each have a required pulling force, so that it is ensured that the corrugated tube cannot become detached from the nipple due to vibrations during normal driving of the motor vehicle.
  • FIG. 1 shows a sectional illustration of a part of a corrugated tube 1 which is to be connected to a nipple.
  • the corrugated tube shown has a preferably cylindrical body which extends in the axial direction and comprises wave crests 2 and wave troughs 3 which extend in the circumferential direction.

Furthermore, it can be seen from this figure that the bevel 7 of the nipple 5 is enclosed by the bevel 10 of the casing 9. In this case, the annular ring provided in the area of the bevel 10 shaped elevation 11 improves the sealing of the device against unwanted leakage of liquid.
