Abstract

The device fits on the ends of exhaust pipes of military, civil, or public works vehicles and is designed to prevent the problems of obstruction by foreign bodies, such as stoppers, rags or bits of wood. It is produced as a sleeve, which can be fitted to the end of the exhaust pipe, by welding, or it can be produced as an integral part of the exhaust pipe itself. The device is formed as an outlet tube (1), in steel and of 143mm in length. It has a series of perforations (2) arranged in rows around the outer cylindrical surface. A closing plate (3) is fitted to the open end and has at least one hole (4), which has a diameter smaller than the internal diameter of the tube itself. USE/ADVANTAGE - It prevents any foreign body from obstructing the free flow of exhaust gases.

Description

DESCRIPTION
L'invention vise un dispositif destiné à éviter les risques d'obstruction par des corps étrangers tels que bouchons, chiffons, morceaux de bois, etc... des sorties des tuyaux d'échappement des moteurs des véhicules autos, militaires, civils et travaux publics caractérisé en ce qu'il est constitué par un conduit (1) de sortie en acier de 143 millimètres de longueur presentant sur sa surface de multiples perforations de 15 millimètres, 20 au total soit 4 rangees de 5 (2).DESCRIPTION
The invention relates to a device intended to avoid the risks of obstruction by foreign bodies such as plugs, rags, pieces of wood, etc. of the outlets of the exhaust pipes of the engines of automobile, military, civil and work vehicles. public characterized in that it is constituted by a steel outlet duct (1) of 143 millimeters in length having on its surface multiple perforations of 15 millimeters, 20 in total, ie 4 rows of 5 (2).

En extrémite une plaque de fermeture (3) pourvue d'un trou (4) de 15 millimètres soit en tout 21 perforations. Son diamètre extérieur est de 43 millimètres (5), son diamètre intérieur est de 35 millimètres (6), côté soudure les trous s'arrêtent à 19 millimètres du bord (7) côte fond à 10 millimètres du bord de la plaque (8).At the end, a closing plate (3) provided with a hole (4) of 15 millimeters, that is to say a total of 21 perforations. Its outside diameter is 43 millimeters (5), its inside diameter is 35 millimeters (6), welding side the holes stop at 19 millimeters from the edge (7) bottom edge at 10 millimeters from the edge of the plate (8) .

Le dispositif destiné à éviter les risques d'obstruction par des corps étrangers des sorties de tuyauteries d'échappement des moteurs de véhicules autos, militaires, civils, travaux publics est caractérisé en ce qu'il est constitué d'un conduit de sortie (1) présentant sur sa surface de multiples perforations (2) et en extrémité une plaque de fermeture (3) dans laquelle est ménagée au moins une ouverture (4) de diamètre plus faible que le diamètre intérieur du conduit.The device intended to avoid the risks of obstruction by foreign bodies of the exhaust pipe outlets of the engines of cars, military, civil, public works vehicles is characterized in that it consists of an outlet duct (1 ) having on its surface multiple perforations (2) and at the end a closure plate (3) in which is formed at least one opening (4) of smaller diameter than the inside diameter of the conduit.

Ce dispositif est réalisé soit sous forme d'un embout sépare destine à être rapporté par soudure sur la tuyauterie d'échappement soit est réalisé directement sur la tuyauterie d'échappement elle-même.This device is produced either in the form of a separate end piece intended to be attached by welding to the exhaust piping or is produced directly on the exhaust piping itself.

Avec ce dispositif, il est bien évident qu'aucun corps étranger ne peut obstruer la sortie des gaz donc le départ et la marche des moteurs ne peuvent être contraries. With this device, it is quite obvious that no foreign body can obstruct the exit of the gases therefore the starting and the running of the engines cannot be prevented.
