Description
Buse pour carburateur de moteur à explosion. L'invention a pour objet une buse pour carburateur de moteur à explosion.
Le dessin ci-joint en montre schématique ment et à titre d'exemples, deux formes d'exé cution.
La fig. 1 est une coupe longitudinale d'une première forme d'exécution représentée montée contre la paroi intérieure d'une canalisation usuelle 2 d'un carburateur dont le papillon de réglage est représenté en 3, l'arrivée d'es sence étant indiquée en 4.
La fig. 2 est une vue par-dessus, et la fig. 3 une vue par-dessous de la fig. 1.
La fig. 4 montre une seconde forme d'exé cution disposée dans une canalisation d'un carburateur.
Les surfaces externe et interne de la buse 1 représentée en fig. 1 à 3 sont composées chacune de deux parties tronconiques réunies par leur petite base, la surface extérieure étant telle qu'elle ménage, entre elle et la surface intérieure de la canalisation 2 dans laquelle elle est placée, une chambre 5 de passage d'air additionnel. Le bout extrême de la buse présente des dents 9 venant en contact avec la surface intérieure de la cana lisation, des ouvertures 7 étant ménagées entre les dents 9 pour le passage de l'air additionnel de la chambre 5 dans la canalisa tion. A son autre bout extrême, la buse pré sente des dents 8 venant en contact avec la canalisation, des ouvertures 6 étant ménagées entre ces dents 8 pour l'entrée de l'air addi tionnel dans la chambre 5.
Comme l'on montré des essais, l'emploi de la buse représentée améliore le remplissage de la chambre d'explosion; ne créant pas de tourbillons, elle ne trouble pas l'aspiration mais, au contraire, l'accélère; elle ne cause pas de dépression entre elle et la canalisation; enfin elle permet à l'appel d'air additionnel d'essuyer la condensation des gaz sur la pa roi de la canalisation et de s'en saturer pour améliorer la carburation par l'utilisation pres que complète du carburant.
Avec la buse représentée en fig. 4, l'air additionnel s'échappe toujours par des ouver tures de sortie 7, mais la buse comporte une partie 10 qui est telle que sa surface exté rieure est en contact avec la surface intérieure de la canalisation, de sorte que la chambre de passage de l'air additionnel ne règne que sur une portion<B>5.</B> de cette buse, commu niquant, d'une part, avec les ouvertures 7, d'autre part, avec l'air extérieur par des ou vertures <B>6.</B> ménagées dans la paroi de la canalisation 2.
Avec cette forme d'exécution, on pourrait régler l'entrée d'air additionnel au moyeu d'une bague 11 perforée, permettant de dé couvrir ou d'obturer plus ou moins les ouver tures 6a, soit à la main, soit par une com mande automatique reliée aux mouvements du papillon usuel.
Nozzle for internal combustion engine carburetor. The subject of the invention is a nozzle for an internal combustion engine carburetor.
The accompanying drawing shows schematically and by way of example, two embodiments.
Fig. 1 is a longitudinal section of a first embodiment shown mounted against the inner wall of a usual pipe 2 of a carburetor, the adjusting butterfly valve of which is shown at 3, the fuel inlet being indicated at 4 .
Fig. 2 is a top view, and FIG. 3 a view from below of FIG. 1.
Fig. 4 shows a second embodiment arranged in a pipe of a carburetor.
The outer and inner surfaces of the nozzle 1 shown in FIG. 1 to 3 are each composed of two frustoconical parts joined by their small base, the outer surface being such that it leaves between it and the inner surface of the pipe 2 in which it is placed, an air passage chamber 5 additional. The extreme end of the nozzle has teeth 9 coming into contact with the interior surface of the pipe, openings 7 being formed between the teeth 9 for the passage of additional air from the chamber 5 into the pipe. At its other extreme end, the nozzle has teeth 8 coming into contact with the pipe, openings 6 being made between these teeth 8 for the entry of additional air into chamber 5.
As shown in tests, the use of the nozzle shown improves the filling of the explosion chamber; not creating vortices, it does not disturb the aspiration but, on the contrary, accelerates it; it does not cause depression between it and the pipe; finally, it allows the additional call for air to wipe the condensation of the gases on the pa king of the pipe and to saturate it to improve the carburetion by the almost complete use of the fuel.
With the nozzle shown in fig. 4, the additional air always escapes through outlet openings 7, but the nozzle has a part 10 which is such that its outer surface is in contact with the inner surface of the pipe, so that the passage of the additional air only prevails over a portion <B> 5. </B> of this nozzle, communicating, on the one hand, with the openings 7, on the other hand, with the outside air through or <B> 6. </B> vertures in the wall of the pipe 2.
With this embodiment, the additional air inlet could be adjusted to the hub of a perforated ring 11, making it possible to uncover or close the openings 6a more or less, either by hand or by a automatic control linked to the movements of the usual throttle.
