Description

  

  <B>Circuit hydraulique de refroidissement du moteur</B>     d'un   <B>véhicule</B>    Dans le brevet     principal    N  367006, on a décrit  un circuit hydraulique de refroidissement du     moteur     d'un véhicule qui comprend un vase d'expansion  placé en un     point    refroidi du véhicule situé plus bas  que le     point    haut du circuit.  



  La présente invention se     rapporte    à un circuit       hydraulique    de     refroidissement    tel que     défini    ci-des  sus et qui est     caractérisé    en     ce    que le vase     d7expan-          sion    est     placé    à l'intérieur d'une des     ailes        adjacentes     au     moteur        dans    la partie supérieure de     cette        aile     et en arrière de la roue.  



  Cette position est     avantageuse    car ledit vase est  protégé du     rayonnement        calorifique    du moteur par  une tôle d'auvent et du rayonnement solaire par     l'aile     de la voiture ;     il        est    en outre bien     ventilé    par l'air  circulant dans le passage de roue, et il ne se trouve  pas situé à une     distance        excessive    du     radiateur.     



  Le dessin     annexé    représente, à titre d'exemple,  une     forme    d'exécution du circuit hydraulique     appli-          qué    à une voiture à moteur avant.  



  La     fig.    1 est une vue en coupe     partielle    du cir  cuit dans une direction axiale de la voiture, suivant  la flèche 1 de la     fig.    2.  



  La     fig.    2 est une vue de côté du même circuit,  suivant la flèche II de     la.        fig.    1.  



  Sur le dessin, 101 est le vase d'expansion, 103  le radiateur, 102     la    tubulure reliant le vase au radia  teur, 108 la roue avant     dans    le passage de laquelle  est monté le     vase,    ce passage étant     limité    par la tôle  d'auvent 105 et l'aile 106.  



  Ce vase     d'expansion    101 est constitué par deux       de#mi-coquilles    1011 et 1012 soudées entre elles et  dont les     bords    tombés extérieurs sont pourvus de    boutonnières 107 pour sa     fixation    au moyen     de    bou  lons 1071.  



       Il    est     raccordé,    de façon étanche, à sa     partie          inférieure,    à la tubulure 102.  



  Il est en outre     raccordé,    à sa     partie    supérieure,  à un clapet     pression-dépression    104 débouchant dans  le coffre moteur.  



  Ce     clapet    a pour but, d'une part, d'éviter une       surpression    trop forte dans, le     circuit    de refroidis  sement en cas     d'échauffement        anormal    du circuit  (pour des     raisons    de     constructions    la     valeur        maxima     de cette surpression a été     fixée    à environ 650     g/cm2),     d'autre part il évite qu'une dépression trop forte, se  produisant lors du     refroidissement,

      vienne troubler  le bon     fonctionnement    de     la    pompe à eau et du       calorstat    (cette valeur pourra être de -50 à  <I>-70</I>     g/cm2).     



  Au cours du     montage    le radiateur et la     tubulure     102 sont     complètement        remplis    d'eau et le vase       d'expansion    est     rempli    jusqu'au quart de sa hau  teur. Le bouchon de     remplissage    est ensuite plombé.



  <B> Hydraulic circuit for cooling the engine </B> of a <B> vehicle </B> In main patent N 367006, a hydraulic circuit for cooling the engine of a vehicle has been described which comprises a coolant tank. expansion placed at a cooled point of the vehicle located lower than the high point of the circuit.



  The present invention relates to a hydraulic cooling circuit as defined above and which is characterized in that the expansion vessel is placed inside one of the wings adjacent to the engine in the upper part of this. wing and back of the wheel.



  This position is advantageous because said vessel is protected from heat radiation from the engine by a canopy sheet and from solar radiation by the wing of the car; it is also well ventilated by the air circulating in the wheel arch, and it is not located at an excessive distance from the radiator.



  The appended drawing shows, by way of example, an embodiment of the hydraulic circuit applied to a front engine car.



  Fig. 1 is a partial sectional view of the circuit in an axial direction of the car, along arrow 1 of FIG. 2.



  Fig. 2 is a side view of the same circuit, along arrow II of the. fig. 1.



  In the drawing, 101 is the expansion tank, 103 the radiator, 102 the pipe connecting the tank to the radiator, 108 the front wheel in the passage of which the tank is mounted, this passage being limited by the cowl plate 105 and wing 106.



  This expansion vessel 101 is made up of two # mid-shells 1011 and 1012 welded together and the outer flanged edges of which are provided with buttonholes 107 for its fixing by means of bolts 1071.



       It is connected, in a sealed manner, at its lower part, to the tubing 102.



  It is also connected, at its upper part, to a pressure-vacuum valve 104 opening into the engine compartment.



  The purpose of this valve is, on the one hand, to avoid an excessively high overpressure in the cooling circuit in the event of abnormal heating of the circuit (for construction reasons, the maximum value of this overpressure has been set at approximately 650 g / cm2), on the other hand it prevents too strong a depression, occurring during cooling,

      disturb the correct functioning of the water pump and the calorstat (this value may be from -50 to <I> -70 </I> g / cm2).



  During assembly, the radiator and the pipe 102 are completely filled with water and the expansion tank is filled to a quarter of its height. The filler cap is then sealed.
