Abstract

1. Arrangement of a degassing box provided with a filler cap (11) and part of a liquid cooling circuit of a heat engine of a vehicle with a cab, said box being connected to the circuit by at least one flexible conduit (10), characterised in that the degassing box (8) is mounted on a support (15, 16) which is pivotal about a fixed axis (17, 18) with respect to the cab of the vehicle so as to allow a limited tilting of the degassing box and facilitate access to the filler cap.

Description

La présente invention est due à la collaboration de Monsieur Gilles BAILLEUX,The present invention is due to the collaboration of Mr. Gilles BAILLEUX,

Elle concerne un circuit de refroidissement par liquide d'un moteur thermique, notamment sur un véhicule automobile. De façon plus précise, elle concerne l'agencement de la boîte de dégazage dont est muni un tel circuit.It relates to a liquid cooling circuit of a heat engine, in particular on a motor vehicle. More specifically, it relates to the arrangement of the degassing box with which such a circuit is provided.

Il est en effet nécessaire, sur un circuit de refroidissement par liquide d'un moteur thermique, de prévoir une boîte de dégazage destinée à recueillir les gaz qui peuvent apparaître en un point quelconque du circuit. Cette boîte doit être placée en partie haute, par rapport au reste du circuit, et elle comporte habituellement un bouchon fermant un orifice par lequel se fait le remplissage en liquide.It is indeed necessary, on a liquid cooling circuit of a heat engine, to provide a degassing box intended to collect the gases which may appear at any point of the circuit. This box must be placed in the upper part, relative to the rest of the circuit, and it usually includes a plug closing an orifice through which the liquid is filled.

Or, il peut arriver que, par manque de place, ledit orifice soit d'accès particulièrement difficile.However, it may happen that, for lack of space, said orifice is particularly difficult to access.

L'invention se propose de remédier à cet inconvénient grâce à un agencement simple procurant un bon accès à l'orifice de remplissage, même lorsque la boîte de dégazage est disposée en dessous et à une très faible distance d'une partie fixe.The invention proposes to overcome this drawback by means of a simple arrangement providing good access to the filling orifice, even when the degassing box is placed below and at a very short distance from a fixed part.

Suivant l'invention, le circuit de refroidissement par liquide d'un moteur thermique, comportant une bofte de dégazage munie d'un bouchon de remplissage et reliée audit circuit par au moins un conduit souple, est caractérisé en ce que la boîte de dégazage est montée sur un support articulé autour d'un axe fixe, en vue d'autoriser un basculement limité de la boîte de dégazage, permettant d'accéder au bouchon de remplissage.According to the invention, the liquid cooling circuit of a heat engine, comprising a degassing box provided with a filling plug and connected to said circuit by at least one flexible duct, is characterized in that the degassing box is mounted on a support articulated around a fixed axis, in order to authorize a limited tilting of the degassing box, allowing access to the filling plug.

Un exemple de réalisation de l'invention fait l'objet de la description qui suit, en référence aux dessins joints dans lesquels :

  • - la Fig. 1 est une vue de face partielle d'un véhicule montrant un circuit de refroidissement agencé suivant l'invention ;
  • - la Fig. 2 est une coupe suivant la ligne 2-2 de la Fig, 1.
An exemplary embodiment of the invention is the subject of the description which follows, with reference to the accompanying drawings in which:
  • - Fig. 1 is a partial front view of a vehicle showing a cooling circuit arranged according to the invention;
  • - Fig. 2 is a section along line 2-2 of FIG, 1.

Dans l'exemple décrit, l'invention est appliquée à un véhicule utilitaire 1, à cabine avancée, dont on a notamment représenté le pare-brise 2, le tableau de bord 3, le volant de direction 4 et le capot 5 enveloppant le moteur.In the example described, the invention is applied to a utility vehicle 1, with an advanced cabin, of which the windshield 2, the dashboard 3, the steering wheel 4 and the hood 5 enveloping the engine have been shown. .

Ce moteur comporte, de façon classique, un circuit de refroidissement par liquide comportant, en particulier, un radiateur 6, une pompe de circulation 7 et une boîte de dégazage 8. Cette dernière est reliée, par deux conduits souples 9 et 10, d'une part au radiateur 6, d'autre part, à la pompe 7, et elle comporte un bouchon de remplissage 11.This engine comprises, in a conventional manner, a liquid cooling circuit comprising, in particular, a radiator 6, a circulation pump 7 and a degassing box 8. The latter is connected, by two flexible conduits 9 and 10, of on the one hand to the radiator 6, on the other hand, to the pump 7, and it includes a filling plug 11.

Comme il apparaît sur la Fig. 2, la boite de dégazage est disposée entre un tablier 12 et une calandre 13, de telle sorte que le bouchon 11 se trouve au-dessous, et à une courte distance, d'une tôle de structure 14, sensiblement horizontale.As it appears in FIG. 2, the degassing box is disposed between an apron 12 and a grille 13, so that the plug 11 is located below, and at a short distance, from a substantially horizontal sheet metal 14.

Suivant l'invention, la boîte de dégazage 8 est portée par un support basculant constitué par deux bras 15, 16 articulés sur deux chevilles 17,18 portées par des tôles 19, 20 sensiblement verticales.According to the invention, the degassing box 8 is carried by a tilting support constituted by two arms 15, 16 articulated on two pegs 17,18 carried by sheets 19, 20 substantially vertical.

Comme il est classique sur ce genre de véhicule, la calandre 13 est amovible et, lorsqu'elle est en place, la boite de dégazage 8 est immobilisée par deux plots 21, 22 en matière élastique, fixés respectivement sur le tablier 12 et sur la calandre 13.As is conventional on this type of vehicle, the grille 13 is removable and, when it is in place, the degassing box 8 is immobilized by two studs 21, 22 made of elastic material, fixed respectively on the bulkhead 12 and on the grille 13.

Lorsque cette dernière est déposée, la boite de dégazage 8 peut être basculée vers l'avant, ce mouvement de basculement étant limité par appui du bras 15 contre un bord plié 23 de la tôle 19. Dans la position basculée vers l'avant, comme représenté en trait mixte sur la Fig. 2, le bouchon 11 se trouve dégagé de la tôle horizontale 14 ce qui permet très facilement de faire le remplissage du circuit de refroidissement ou, simplement, de contrôler le niveau du liquide.When the latter is deposited, the degassing box 8 can be tilted forward, this tilting movement being limited by pressing the arm 15 against a folded edge 23 of the sheet 19. In the tilted forward position, as represented in phantom in FIG. 2, the plug 11 is released from the horizontal sheet 14 which makes it very easy to fill the cooling circuit or, simply, to control the level of the liquid.
