Abstract

L'invention concerne un réservoir à eau pour moteur diesel monocylindrique à vaporisation. Le réservoir à eau comprend un couvercle supérieur et un corps inférieur qui sont assemblés pour former un réservoir à eau solidaire de manière que ce réservoir soit relié au réservoir de carburant de façon compatible. La trémie et l'intégralité du couvercle supérieur du réservoir à eau sont obtenus par extrusion, la partie inférieure du réservoir à eau se trouve sur le moteur diesel. Le couvercle supérieur du réservoir à eau peut être monté librement et retiré du corps solidaire ce qui confère au réservoir à eau de nouvelles fonctions, à savoir il peut facilement contenir des outils et des pièces de rechange susceptibles de se perdre lors de leur transport ou stockage et l'espace de rangement s'en trouve réduit. Grâce à cette configuration, le réservoir est plus facile à fabriquer. Suite à l'extrusion à froid, il n'est plus nécessaire de souder après l'opération d'emboutissage et il est, par conséquent, plus facile de fabriquer un réservoir à eau pratique et bon marché.
