Definitions

  • the invention relates to a ventilation device for a fuel tank, in particular of a motor vehicle, with a ventilation line leading to the outside of the fuel tank, which is connected to the interior of the fuel tank via a ventilation opening of a ventilation connection with a larger flow cross section and a ventilation opening of a ventilation connection with a small flow cross section the ventilation connection with its ventilation opening at a level lower than the ventilation opening of the ventilation connection opens into the interior of the fuel tank and the interior of the fuel tank can be shut off from the ventilation line by a roll-over valve.
  • the ventilation opening and ventilation connection serves to discharge gas displaced by the filled fuel in the fuel tank to the outside during a refueling process.
  • the ventilation opening which is higher than the ventilation opening, has only a small cross-section, acting as a throttle, through which not enough gas can be discharged to prevent the pressure build-up described during refueling.
  • the ventilation opening serves to discharge the gas volume, which increases when the temperature rises, so that there is no pressure increase in the fuel tank.
  • the roll-over valves block the ventilation openings in the corresponding position of the motor vehicle.
  • the object of the invention is therefore to provide a ventilation device of the type mentioned, which has a simple structure and requires only a small amount of space.
  • a single ventilation line then leads from the roll-over valve either to the filler neck of the fuel tank and from there via an activated carbon filter to the outside.
  • the ventilation line can also be led directly to the outside via an activated carbon filter.
  • the ventilation connection can be an ventilation pipe protruding into the fuel tank, the interior of which is connected to the interior of the fuel tank via the ventilation opening.
  • the ventilation opening is a continuous radial recess in the ventilation pipe, which connects the interior of the fuel tank with the interior of the ventilation pipe at a higher level than the ventilation opening, no additional components and no additional installation space are required for the ventilation.
  • the ventilation opening can be a ventilation pipe of smaller cross-section than the cross-section of the ventilation pipe.
  • the ventilation opening can flow into its interior at a level of approximately 85% to 90% of the total volume of the fuel tank.
  • vent opens near the highest point of the fuel tank into its interior, venting of the tank is ensured under largely all operating conditions of the motor vehicle.
  • a blow-out container can be arranged behind the roll-over valve, which serves to separate fuel particles contained in the gas derived from the fuel container and to return them to the fuel tank.
  • the roll-over valve is arranged inside the fuel tank, the amount of fuel that permeates outside the fuel tank is kept particularly low.
  • the roll-over valve can also be arranged outside the fuel tank.
  • the roll-over valve preferably has a through opening which can be closed by a closing member and which leads from the ventilation duct to the ventilation duct, the closing member being able to be acted upon in the closing direction by a gravity body and / or a floating body.
  • a gravity body When the motor vehicle is in a head position, the gravity body applies its weight to the closing member and holds it on the through opening, so that no fuel can leak out.
  • the floating body serves to act upon the closing member closing the through opening if there should be such an increase in the fuel in the fuel tank that the floating body is caused to float.
  • the ventilation line can lead directly to an activated carbon filter or to a filler neck of the fuel tank and from there to an activated carbon filter.
  • Figure 1 shows a section of a side view of a fuel tank a ventilation system on average
  • FIG. 2 shows an enlarged illustration of the ventilation device according to FIG. 1.
  • the fuel tank 1 shown in FIG. 1 has an opening 3 on its upper wall 2, into which a ventilation device 4 is inserted to close the opening 3.
  • the fuel tank 1 has a filler neck 5 opening at its upper right area.
  • the ventilation device 4 has a cover part 6 with a flange 7, which can be inserted into the opening 3 until the flange 7 rests on the upper wall 2 and through which the opening 3 can be closed.
  • An outwardly leading connection piece 8 with a ventilation line leading to the outside of the fuel tank 1 is formed in one piece on the cover part 6.
  • the tank-side end of the ventilation line 9 is a through opening 11 designed as a valve seat of a rollover valve 10, which can be closed by a closing member 12.
  • the closing member 12 is moved towards the outside of the tank for closing.
  • a ventilation pipe 13 extends coaxially to the through opening 11 approximately vertically into the interior 18 of the fuel tank 1, which is attached with its upper end to the cover part 6 and forms a guide for the closing member 12.
  • a freely moving ball forming a gravity body 14 is furthermore arranged in the ventilation tube 13, through which the closing member 12 is subjected to the force of its weight against the valve seat of the through opening 11 when the tank is in the appropriate position, and this closes.
  • a grating 15 is arranged below the ball in the ventilation tube 13, but only insignificantly reduces the passage cross section of the ventilation tube 13.
  • the ventilation pipe 13 opens into its interior 18 with its ventilation opening 16 at a height 17 of a fill level of 85% of the total volume of the fuel tank 1.
  • a continuous recess is formed in the ventilation pipe 13 in a radially directed manner, which forms a ventilation connection 19 which, with its ventilation.
  • opening 21 opens into the interior 18 of the fuel tank 1.
  • the area in the ventilation pipe 13 between the ventilation connection 19 and the through-opening 11 forms a ventilation channel 20 into which the gas entering the ventilation pipe 13 from the interior 18 of the fuel tank 1 via the ventilation opening 16 and the ventilation opening 21 together via the roll-over valve 10 and the through opening 11 of the ventilation line 9 is supplied.
  • the ventilation opening 16 has a considerably larger passage cross section than the ventilation opening 21 acting as a throttle, so that gas to be displaced during refueling can be discharged unhindered via the ventilation opening 16 as long as this ventilation opening 16 is not yet covered by the fuel in the fuel tank 1 and thus blocked becomes.
  • Such displaced gas volumes during refueling are, however, too large to be discharged through the remaining ventilation opening 21, so that a pressure which switches off the fuel nozzle builds up in the fuel tank 1.
  • the ventilation line 9 is continued from the connecting piece 8 via a bubble tank 22 to the filler neck 5 and opens there into the upper end thereof. Fuel particles contained in the gas are separated by the bubble tank and returned to the interior 18 of the fuel tank 1 via the ventilation line 9 and the open roll-over valve 10.

Abstract

L'invention concerne un dispositif de ventilation et d'aération pour le réservoir de carburant (1) d'un véhicule, comportant un conduit d'aération (9) menant l'air vers l'extérieur du réservoir (1), ce conduit étant relié à l'intérieur (18) du réservoir (1) par un orifice de ventilation (16) d'un raccord de ventilation à grande section de passage et par un orifice d'aération (21) d'un raccord d'aération à section de passage inférieure. Le raccord de ventilation et l'orifice de ventilation (16) s'ouvrent à l'intérieur du réservoir (1) à une hauteur (17) de niveau de remplissage plus faible que l'orifice d'aération (19) du raccord d'aération. Un clapet anti-fuite (10) permet de verrouiller l'intérieur (18) du réservoir (1) du conduit d'aération (9). Les raccords de ventilation et d'aération débouchent dans un conduit d'aération commun (20), qui mène à l'unique clapet anti-fuite (10), à la sortie duquel est raccordé le conduit d'aération (9).
