La présente invention sera mieux comprise à l'étude d'un groupe-moteur d'un véhicule automobile équipé d'un réservoir d'huile de lubrification, décrit à titre d'exemple non limitatif et illustré par le dessin sur lequel :
- la figure 1 représente une vue longitudinale d'un groupe-moteur d'un véhicule automobile, le réservoir d'huile de lubrification étant en coupe ;
- et la figure 2 représente une vue en bout dudit groupe-moteur, le réservoir d'huile de lubrification étant en coupe transversale.
- FIG. 1 represents a longitudinal view of an engine group of a motor vehicle, the lubricating oil reservoir being in section;
- and Figure 2 shows an end view of said engine group, the lubricating oil reservoir being in cross section.
En se reportant aux figures, on voit qu'on a représenté un
groupe-moteur 1 d'un véhicule automobile, dont l'ensemble des
équipements est porté par un carter 2 et à l'avant duquel est prévu un
groupe-ventilateur 3.Referring to the figures, we see that a
motor unit 1 of a motor vehicle, all of which
equipment is carried by a

véhicule dont la structure ou caisse comprend deux longerons 5 qui
s'étendent de part et d'autre et à distance du groupe-moteur 1.The engine group 1 is arranged in a
Le groupe-moteur 1 est équipé d'une bâche à huile 6 de faible
épaisseur et de grandes surfaces principales opposées, dont les parois
sont par exemple en tôle.The engine group 1 is fitted with a
Cette bâche 6 présente une partie 7 qui s'étend sensiblement
horizontalement en-dessous et à distance du groupe-moteur 1, ainsi que
des flancs longitudinaux 8 qui s'étendent vers le haut de telle sorte que
la bâche 6, en coupe transversale, se présente sensiblement sous la
forme d'un U dont le fond est formé par la partie 7 et dont les branches
8 vont en s'écartant, les bords supérieures des flancs 8 s'étendant juste
en-dessous des longerons 5.This
Dans l'exemple représenté, la partie 7 de la bâche 6 présente
une partie avant 7a qui est située à un niveau inférieur à sa partie
arrière 7b, ces parties 7a et 7b étant reliées par une partie intermédiaire
7c inclinée vers l'avant.In the example shown,
La bâche 6 est suspendue à la caisse du véhicule grâce à des
bandes de liaison 9 qui relient les bords supérieurs de ses flancs 8 aux
parties inférieures des longerons 5, ces bandes 9 incorporant de
