Description
Pot d'échappement La présente invention a pour objet un pot d'échappement pour moteur à combustion interne comprenant un boîtier allongé présentant à une de ses extrémités un orifice d'entrée muni de moyens pour son raccordement au conduit d'échappement du moteur et, à son autre extrémité, d'un orifice de sortie des gaz brûlés, caractérisé par le fait que ce boîtier comprend deux éléments assemblés l'un à l'autre, chacun de ceux-ci étant pourvu d'une paroi intérieure façonnée de manière à former une cavité limitée dans le sens de la longueur du boîtier par deux bossages présentant des canaux longitudinaux d'évacuation des gaz brûlés, une garniture en ma tériel isolant étant intercalée entre les parois de cha que élément.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution du pot d'échappement objet de l'invention.
La fig. 1 en est une vue en coupe axiale longitu- dinale suivant I-I de la fig. 2 ; la fig. 2 est une vue en coupe suivant II-II de la fig. 1 ; la fig. 3 est une vue en coupe suivant III-III de la fig. 1 ; la fig. 4 est une vue en coupe suivant IV-IV de la fig. 1.
Le pot d'échappement représenté comprend un boîtier allongé 1 présentant à une de ses extrémités un orifice d'entrée 2 muni de moyens pour son raccordement au conduit d'échappement d'un mo teur à combustion interne et, à son autre extrémité, un orifice 3 de sortie des gaz brûlés. Le boîtier 1 est formé par deux éléments 4 et 5 présentant des parois en tôle 6 et 7 pourvues latéra lement de rebords extérieurs 8 et 9, ces derniers étant placés en regard et assemblés par soudage.
Chaque élément 4 et 5 présente une paroi inté rieure 10 de même forme que la paroi extérieure correspondante de celle-ci, à laquelle elle est sou dée par ses bords ; chaque paroi 10 est en tôle façonnée percée de trous 11 et présentant une ou verture médiane 12 limitée dans le sens de la lon gueur du pot d'échappement par deux bossages 13 présentant des canaux longitudinaux coaxiaux 14, les canaux 14 d'un élément étant en regard de ceux de l'autre élément ; le long de ces canaux 14 sont destinés à se déplacer, dans le sens de la flèche 15, les gaz brûlés entrant par l'orifice 2 et sortant par l'orifice 3.
A l'extrémité avant de chaque paroi intérieure 10, entre l'orifice d'entrée 2 et le bossage 13 cor respondant, est aménagée une cavité 16 ; de même, à l'extrémité aval de chaque paroi intérieure 10, entre l'orifice de sortie 3 et le bossage 13 corres pondant, est aménagée une cavité 17 semblable à 16.
Entre la paroi 6 ou 7 d'un élément et la paroi intérieure 10 correspondante est placée une garni ture en matériel isolant, en fibre de verre, par exem ple ; cette dernière est destinée à freiner les oscilla tions desdites parois intérieures.
Le fonctionnement du pot d'échappement repré senté est le suivant Les gaz d'échappement provenant du moteur pénètrent dans ledit pot par l'orifice 2, se détendant dans la cavité 16 puis pénétrant par les canaux lon gitudinaux 14 dans la cavité 12 où ils continuent à se détendre<B>;</B> ensuite, ces gaz aboutissent à la cavité 17, après s'être déplacés dans les canaux lon gitudinaux 14, où ils se détendent encore avant de s'échapper au dehors par l'orifice 3.
Il est prévu, en variante, de réaliser les parois 10 en tôle non perforée.
Exhaust The present invention relates to a muffler for an internal combustion engine comprising an elongated housing having at one of its ends an inlet port provided with means for its connection to the engine exhaust duct and, at its other end, an outlet for the burnt gases, characterized in that this housing comprises two elements assembled together, each of these being provided with an internal wall shaped so as to form a cavity limited in the direction of the length of the casing by two bosses having longitudinal channels for evacuating the burnt gases, a lining of insulating material being interposed between the walls of each element.
The appended drawing represents, by way of example, an embodiment of the exhaust pipe which is the subject of the invention.
Fig. 1 is a view in longitudinal axial section along I-I of FIG. 2; fig. 2 is a sectional view along II-II of FIG. 1; fig. 3 is a sectional view along III-III of FIG. 1; fig. 4 is a sectional view along IV-IV of FIG. 1.
The muffler shown comprises an elongated housing 1 having at one of its ends an inlet orifice 2 provided with means for its connection to the exhaust duct of an internal combustion engine and, at its other end, a burnt gas outlet 3. The housing 1 is formed by two elements 4 and 5 having sheet metal walls 6 and 7 provided laterally with outer edges 8 and 9, the latter being placed opposite and assembled by welding.
Each element 4 and 5 has an interior wall 10 of the same shape as the corresponding exterior wall thereof, to which it is welded by its edges; each wall 10 is made of shaped sheet metal pierced with holes 11 and having a central or median opening 12 limited in the direction of the length of the muffler by two bosses 13 having coaxial longitudinal channels 14, the channels 14 of an element being next to those of the other element; along these channels 14 are intended to move, in the direction of arrow 15, the burnt gases entering through orifice 2 and exiting through orifice 3.
At the front end of each interior wall 10, between the inlet orifice 2 and the corresponding boss 13, a cavity 16 is provided; likewise, at the downstream end of each inner wall 10, between the outlet orifice 3 and the corresponding boss 13, there is a cavity 17 similar to 16.
Between the wall 6 or 7 of an element and the corresponding inner wall 10 is placed a lining of insulating material, fiberglass, for example; the latter is intended to slow down the oscillations of said interior walls.
The operation of the muffler shown is as follows The exhaust gases from the engine enter said muffler through the orifice 2, relaxing in the cavity 16 then entering through the longitudinal channels 14 into the cavity 12 where they continue to relax <B>; </B> then these gases end in cavity 17, after having moved into longitudinal longitudinal channels 14, where they further relax before escaping out through the orifice 3.
As a variant, provision is made for the walls 10 to be made from non-perforated sheet metal.
