eRFCiAUE'3.'lUR D'EAU* D'ALIMENTATION OONSTrrUE DI7,S T1BO> ET DES COLLECTEURS TRANSVERSAUX EN FONTE"
Il est connu d'utiliser des raccords comme moyen de con- nexion entre les tubes en fonte des réchauffeurs d'eau à gaz chauds et les collecteurs transversaux de ces réchauffeurs.
Ce moyen de connexion n'offre pas l'élasticité néces- saire pour permettre l'absorption des chocs ou des tensions de dilatation pouvant se produire dans les tubes.
Ce désavantage est supprimé, suivant l'invention, par le nouveau raccord en forme de tube ondulé. Les Figs. 1 à 5 re- présentent des raccords présentant une ou plusieurs ondu- lations et dont les extrémités vissées ou serties, , d'une part, dans les tubes en fonte., et d'autre part dans les

collecteurs transversaax. Grâce aux dites ondulations , ces éléments de connexion (raccords) possèdent une élasticité remarquable, ce qui leur permet d'absorber toutes les tensions qui se produisent entre les tubes.et les collecteurs par suite de chocs ou de la dilatation.
Lorsqu'un tube doit être retiré d'un groupe de plusieurs tubes, aux fins de réparation par exemple, les longueurs de tubes, situées de part et d'autre du tube devant être changé peuvent être écartées à leur point de fixation et ceci grâce à l'élasticité des raccords en forme de tubes ondulés, de sorte que le tube en question est dégagé et peut alors être changé.

EMI1.1
eRFCiAUE'3.'lUR OF WATER * OONSTrUE DI7, S T1BO> SUPPLY AND CAST IRON TRANSVERSE COLLECTORS "
It is known to use fittings as a means of connection between the cast iron tubes of hot gas water heaters and the transverse manifolds of these heaters.
This connection means does not provide the elasticity necessary to allow the absorption of shocks or expansion stresses which may occur in the tubes.
This disadvantage is eliminated, according to the invention, by the new connector in the form of a corrugated tube. Figs. 1 to 5 represent fittings having one or more corrugations and the ends of which are screwed or crimped, on the one hand, in the cast iron tubes., And on the other hand in the
<Desc / Clms Page number 2>
transversaax collectors. Thanks to said corrugations, these connection elements (fittings) have a remarkable elasticity, which allows them to absorb all the tensions which occur between the tubes. And the collectors as a result of shocks or expansion.
When a tube must be removed from a group of several tubes, for repair purposes for example, the lengths of tubes, located on either side of the tube to be changed can be moved away at their point of attachment and this thanks to to the elasticity of the fittings in the form of corrugated tubes, so that the tube in question is released and can then be changed.
