Definitions

  • the present invention relates generally to the ventilation of motor vehicle headlamps.
  • a constant concern in the design of a ventilation device for the interior space of a headlamp resides in that more or less charged air in humidity must be able to enter or exit the projector, depending on differential pressures may exist at the same time that penetration of water, mud, soiling, etc. in said interior space.
  • Document FR-A-2 660 412 teaches a device for ventilation which includes, on the outside of the housing, a generally leads in a "U" shape with one end open is sheltered from direct water splashes and, on the inside of the housing, one opening opening at a time axially and radially in the interior space of the projector.
  • a hydrophobic filter is interposed on the route ventilation.
  • Such a device is however disadvantageous in that that it has limited effectiveness when you want ability to do without such a hydrophobic filter, in particular when the projector is directly exposed to rain under pressure or when fording.
  • the plug described in this document must be include in its fund specific means for the keep away from the free end of the game ventilation system, otherwise the elbow which connects the first and second channels is closed, and ventilation is no longer provided. This increases the cost of comes back from the set.
  • the present invention aims to overcome these drawbacks and provide ventilation that is not likely to be defect, and an improved liquid barrier effect.
  • the part of the ventilation device without plug can be realized by injection molding without the need for drawers or analogs, i.e. with a simple molding tool and economical, while offering the free end of the part which projects inwards a vertical wall of significant height, favorable to the barrier effect vis-à-vis liquids.
  • the reference 100 denotes a wall, for example the rear wall, of a projector housing.
  • first protruding portion 110 coming for example molding with the housing and whose outline is in this case generally cylindrical with a horizontal axis.
  • a second protruding part 120 Inward of the housing (to the left) extends a second protruding part 120, preferably also coming from molding. Its outline is generally semi-cylindrical horizontal axis. The protruding parts 110 and 120 are coaxial in this case.
  • a plug 130 is mounted so removable on this end to close it. It has a circular shutter part 131 and a flange peripheral 132 oriented essentially axially.
  • the plug is held in place by force elastic tightening exerted by its collar on the outside of the protruding part 110, the plug being made for example of rubber.
  • the cylindrical part 110 comprises, on all of its longitudinal extent and in its lower region a slit 111.
  • the semi-cylindrical contour portion 120 includes a flat bottom wall 124, a semi-cylindrical top wall 122, an end wall 123 and an opening 121 formed in the wall 122, located near the wall terminal 123 and opening up into space inside of the projector.
  • a baffle-like partition 112 extends in the part protruding 110 from the wall 100, in the extension of the wall 124.
  • This partition 112 is essentially parallel to the axis of said part 110, and stops at a certain distance from the free end of said part 110.
  • the partition 112 is in this case flat and horizontal.
  • the wall 100 of the housing has an opening semicircular 101 which opens on one side into channel C1 bounded by bulkhead 112 and the upper region of the wall of the protruding part 110, and on the other side in the channel C2 bounded by the projecting part 120.
  • the ventilation air path is formed, in the embodiment described above, through the slot 111, by a channel C3 with which the slot 111 communicates and which is defined in the interior space of part 110 below of the partition 112, between this and the flange 132 of the cap 130, by a bend about 180 ° upwards between the free edge in the axial direction of the partition 112 and plug 130, then through channel C1 and channel C2, and finally through opening 121.
  • Tests conducted with the ventilation device according to the invention have put forward a ventilation quite satisfactory and very good test behavior to rain by pressure and fording.
  • a projector can be equipped with one or several ventilation devices as described above, and the shape and dimensions of the various parts can vary widely from those described and represented.
