Abstract

The filter consists of a housing (1) about 13 cm long by 12 cm in diameter, made e.g. from 50 per cent fiberglass and 50 per cent plastic for small engines and of stainless steel for commercial vehicles, having a stepped intake pipe (2) at one end for fitting into exhaust pipes of different sizes. The housing contains a filter cartridge (5) made from woven non-oxidizing metal fabric, and its outlet (3) is fitted to a detachable cover (4) for replacing the filter. The intake pipe is offset axially to allow the housing to be fitted between the vehicle bodywork and shock absorber.

Description

I, présente invention concerne un dispositif de filtrage d'un
courant de gaz émanant des tuyaux d'échappement des véhi-
cules contenant des particules de carbone et dérives de ce gaz.I, the present invention relates to a device for filtering a
gas flow from vehicle exhaust pipes
cules containing carbon particles and derivatives of this gas.

La a finalitc de cette invention est de réduire les effets de la po
lution de l'environement provoqués et renvoyés dans l'air par
les voitures, camions, bus, roulant à l'essence et tout particu
lièrement au diesel.The purpose of this invention is to reduce the effects of po
lution of the environment caused and returned to the air by
cars, trucks, buses, gasoline powered vehicles and everything
especially diesel.

I, principe de cette invention est de filtrer les fumées émanan-
tes des véhicules et qui éviterait par conséquence, la volatisation dans l'atmosphère de toutes ces particules nocives à la santé
(suie).I, principle of this invention is to filter the fumes emanating
of vehicles and which would consequently prevent the volatilization in the atmosphere of all these particles harmful to health
(soot).

I, dispositif selon cette invention permet de remédier à cet in
convénient, il comporte en effet, selon une première caractéris-
tique :
Un boîtier (corps) fabriqué en fibre de verre (50 %), et en
matière plastique (50 %), pour véhicules de petite cylindrée,
et en inox. pour les utilitaires, afin de supporter des hautes
températures.I, device according to this invention overcomes this in
convenient, it has indeed, according to a first characteristic
tick:
A housing (body) made of fiberglass (50%), and
plastic material (50%), for small displacement vehicles,
and stainless steel. for utilities, to support high
temperatures.

Le dit boîtier a une longueur d'environs 13 cm. et 12 cm. de
diamètre, selon le mode particulier de réalisation :
le dispositif comporte une entrée adecuate au diamètre du tuyau d'échappement des véhicules où il sera fixé, à l'autre
extrémité (sortie) un bout de tuyau, afin qu'il puisse recevoir
la sonde lors d'un contrôl technique anti-pollution.Said case has a length of around 13 cm. and 12 cm. of
diameter, depending on the particular embodiment:
the device has an inlet adecuate to the diameter of the vehicle exhaust pipe where it will be fixed, to the other
end (outlet) a piece of pipe, so that it can receive
the probe during an anti-pollution technical check.

A l'intérieur du boîtier, sera logé un filtre composé en tissu dc
matière métallique inoxidable, afin d'éviter l'oxydation due à la
condensation d'eau, il sera réemplacé régulièrement.Inside the housing, will be housed a dc fabric filter
stainless metal material, to avoid oxidation due to
water condensation, it will be replaced regularly.

Le rôle du filtre c'est de piéger la suie qui est mélangée dans la
fumée émise par la combustion du véhicule.The role of the filter is to trap the soot which is mixed in the
smoke from vehicle combustion.

La figure 1 représente en coupe le dispositif de l'invention. Figure 1 shows in section the device of the invention.

En référence au dessin, le dispositif comporte un boîtier (1), dont l'une des faces latérales est munie d'un tuyau de différents diamètres (2), afin de l'adapter à tout les types de tuyaux d'écha- ppement (entrce), cette partie du corps du boîtier sera décalée par rapport à son axe centralc afin de pouvoir l'ajuster au mieux entre la carrosserie et le para-choc du véhicule.Referring to the drawing, the device comprises a housing (1), one of the side faces of which is provided with a pipe of different diameters (2), in order to adapt it to all types of exhaust pipes (entrce), this part of the housing body will be offset from its central axis in order to be able to adjust it as best as possible between the bodywork and the vehicle bumper.

L'autre extrémité (3), permettra de fixer la sonde pour les contrôles techniques, le couvercle (4), sera démontable afin de remplacer le filtre régulièrement, et il sera fixé à l'aide de vis à 120 .The other end (3), will fix the probe for technical inspections, the cover (4), will be removable in order to replace the filter regularly, and it will be fixed with screws at 120.

Le e filtre (5), composé de tissu métallique inoxidable sera logé à l'intérieur du boîtier (1).  The e filter (5), made of stainless metallic fabric, will be housed inside the housing (1).

Une variante du mme dispositif et de mme conception permettrait de le fixer entre deux pots d'échappement, à la différence que le couvercle ce trouverait sur le corps du boîtier mme. A variant of the same device and of the same design would make it possible to fix it between two exhaust pipes, with the difference that the cover would be on the body of the same case.
