Definitions

  • the invention relates to a holder for a regeneration valve of a fuel evaporation
  • the holder consists of elastic material which is designed in the form of a sleeve.
  • the regeneration valve is inserted into the sleeve and held by elastic deformation of the sleeve.
  • the elastic material is required in order to dampen the operating noises that occur during operation of the regeneration valve, so that no disturbing noises can penetrate into the vehicle interior in particular.
  • the sleeve is, for example, still encompassed by a sheet metal part in order to be screwed to the inner wall of the engine compartment or to the internal combustion engine by means of a screw connection.
  • the sheet metal part is first screwed onto the sleeve, after which the regeneration valve is inserted into the sleeve and turned into its circumferential position is precisely aligned.
  • the regeneration valve is then fixed in the aligned rotational position by means of a fuse in the holder. This can be done, for example, by jamming the sheet metal part with the inserted regeneration valve.
  • the regeneration valve is electrically contacted by means of a pluggable plug. It is necessary to fix the rotational position of the regeneration valve, since violent vibrations sometimes occur during operation of the internal combustion engine and the regeneration valve

Abstract

Les supports de soupape de régénération de la technique antérieure se présentent généralement sous forme d'une gaine en matériau élastique destinée à maintenir la soupape de régénération par déformation élastique. Il est souvent difficile de trouver un emplacement de montage approprié à ce type de support, en raison du grand nombre de composants logés dans le moteur. Le support selon l'invention se présente sous la forme d'un étrier de fixation (1) relié à la soupape de régénération et monté sur une paroi (22) du carter. La forme de l'étrier de fixation (1) permet de trouver une multitude d'emplacements de montage potentiels, car elle est adaptée aux possibilités de montage limitées dans le moteur. Le support de l'invention est conçu pour des soupapes de régénération à commande électromagnétique.
