Abstract
Description
On connait des dispositif d'alimentation en liquide qui comprennent une pompe à ailettes et un moteur électrique à deux sens de rotation pour entraîner la pompe, la disposition étant telle que, dans un premier sens de rotation du moteur, le liquide est refoulé vers une première sortie et, pour le sens de rotation opposé, vers une seconde sortie.Liquid supply devices are known which include a vane pump and an electric motor with two directions of rotation for driving the pump, the arrangement being such that, in a first direction of rotation of the motor, the liquid is discharged to a first outlet and, for the opposite direction of rotation, to a second outlet.
Mais ces dispositifs ne permettent pas d'alimenter trois sorties indépendantes les unes des autres; il faut dans ce cas prévoir une deuxième commande agissant sur une vanne à trois voies.However, these devices do not make it possible to supply three independent outputs from each other; in this case it is necessary to provide a second control acting on a three-way valve.
La présente invention a pour objet un dispositif d'alimentation du circuit de lavage d'un véhicule automobile qui ne comporte qu'une seule pompe et permet d'alimenter trois gicleurs indépendants en agissant sur un commutateur unique. The present invention relates to a device for supplying the washing circuit of a motor vehicle which comprises only one pump and makes it possible to supply three independent nozzles by acting on a single switch.
Ce dispositif est caractérisé en ce qu'il comporte une pompe à ailettes, un moteur à deux sens de rotation et à deux vitesses pour entraîner la pompe, et des moyens pour orienter sélectivement le liquide refoulé, selon la pression de ce liquide et du sens de rotation de la pompe, vers une première sortie, vers une seconde sortie, ou vers une troisième sortie, ces trois sorties alimentant le gicleur du lave-glace arrière, le gicleur du lave-glace avant, et les gicleurs des lave-projecteurs.This device is characterized in that it includes a vane pump, a motor with two directions of rotation and two speeds to drive the pump, and means for selectively orienting the pumped liquid, according to the pressure of this liquid and the direction of rotation of the pump, to a first outlet, to a second outlet, or to a third outlet, these three outlets supplying the nozzle of the rear windscreen washer, the nozzle of the front windscreen washer, and the jets of the headlight washers.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du dispositif d'alimentation selon l'invention, avec référence au dessin annexé dans lequel
La Figure 1 est un schéma de l'installation;
La Figure 2 est une vue en coupe schématique
de la moto-pompe lorsque la pompe est
entraînée à grande vitesse;
La Figure 3 est une vue semblable à la Figure
2, la pompe étant entraînée à faible vitesse;
La Figure 4 montre l'alimentation du moteur.An embodiment of the supply device according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which
Figure 1 is a diagram of the installation;
Figure 2 is a schematic sectional view
motor pump when the pump is
driven at high speed;
Figure 3 is a view similar to Figure
2, the pump being driven at low speed;
Figure 4 shows the motor supply.
A la Figure 1, on voit une moto-pompe 1 qui est reliée par un conduit 2 à un réservoir de liquide 3 et par des conduits 4, 5 et 6 respectivement aux gicleurs des lave-projecteurs 7, au gicleur d'un lave-vitre avant 8 et au gicleur d'un lave-vitre arrière 9. In Figure 1, we see a motor pump 1 which is connected by a conduit 2 to a liquid tank 3 and by conduits 4, 5 and 6 respectively to the nozzles of the headlamp washers 7, to the nozzle of a washer front window 8 and the nozzle of a rear window washer 9.
Comme on le voit aux Figures 2 et 3, la moto-pompe 1 comprend dans un même carter 10, un moteur 11, à deux sens de rotation et à deux vitesses, dont l'arbre de sortie 12 est relié au rotor d'une pompe à ailettes 13. Un commutateur comportant une position d'arrêt et trois positions de travail 14, 15 et 16 permet de faire tourner le moteur 11 respectivement à grande vitesse dans un premier sens de rotation, à petite vitesse dans le premier sens de rotation et à petite vitesse dans le sens de rotation opposé.As seen in Figures 2 and 3, the motor pump 1 comprises in the same housing 10, a motor 11, with two directions of rotation and two speeds, whose output shaft 12 is connected to the rotor of a vane pump 13. A switch comprising a stop position and three working positions 14, 15 and 16 makes it possible to rotate the motor 11 respectively at high speed in a first direction of rotation, at low speed in the first direction of rotation and at low speed in the opposite direction of rotation.
Le carter 10 est conformé de manière que l'admission de la pompe 13 soit reliée au conduit 2 et que son refoulement soit relié dans un premier sens de rotation de la pompe au conduit 6 et dans le sens de rotation opposé à un conduit 17. Le conduit 17 est relié au conduit 4 par une vanne normalement fermée à tiroir 18 soumise à l'action de la pression et d'un ressort antagoniste 19 et au conduit 5 par une vanne normalement ouverte à tiroir 20 soumise à l'action de la pression et d'un ressort antagoniste 21.The casing 10 is shaped so that the inlet of the pump 13 is connected to the duct 2 and its discharge is connected in a first direction of rotation of the pump to the duct 6 and in the opposite direction of rotation to a duct 17. Line 17 is connected to line 4 by a normally closed valve with slide valve 18 subjected to the action of pressure and an opposing spring 19 and to line 5 by a normally open valve with slide valve 20 subjected to the action of pressure pressure and an opposing spring 21.
La communication entre les conduits 5 et 17 est établie lorsque la pompe tourne à petite vitesse et que la pression de refoulement de la pompe est inférieure à, par exemple, 1,5 bar alors que la communication entre les conduits 4 et 17 ne l'est que lorsque la pompe tourne à grande vitesse et que la pression de refoulement est au moins égale à, par exemple, 5 bars. Il est nécessaire que les tiroirs 18 et 20 se déplacent simultanément pour ne pas fermer l'évacuation de la pompe. Communication between lines 5 and 17 is established when the pump is running at low speed and the pump discharge pressure is less than, for example, 1.5 bar while communication between lines 4 and 17 does not is that when the pump is running at high speed and the discharge pressure is at least equal to, for example, 5 bars. It is necessary that the drawers 18 and 20 move simultaneously so as not to close the discharge of the pump.
Lorsque le commutateur est dans la position 14, le moteur 11 tourne à grande vitesse dans le second sens de rotation. Le liquide est refoulé dans le conduit 17 et les tiroirs 18 et 20 sont repoussés de sorte que le conduit 17 est mis en communication avec le conduit 4 et que le liquide est refoulé vers les gicleurs des lave-projecteurs 7 (Figure 2).When the switch is in position 14, the motor 11 rotates at high speed in the second direction of rotation. The liquid is discharged into the conduit 17 and the drawers 18 and 20 are pushed back so that the conduit 17 is placed in communication with the conduit 4 and that the liquid is discharged towards the nozzles of the headlight washers 7 (Figure 2).
Lorsque le commutateur est dans la position 15 ou 16, le moteur tourne à faible vitesse et les tiroirs 18 et 20 sont maintenus en butée par leurs ressorts 19 et 21 (Figure 3). Dans la position 15, la pompe 13 tourne dans le même sens que précédemment de sorte que le liquide est refoulé par les conduits 17 et 5 vers le gicleur du lave-vitre avant 8. Par contre, dans la position 16, la pompe 13 tourne dans le sens opposé et le liquide est refoulé par le conduit 6 vers le gicleur du lave-vitre arrière 9. When the switch is in position 15 or 16, the motor rotates at low speed and the drawers 18 and 20 are held in abutment by their springs 19 and 21 (Figure 3). In position 15, the pump 13 rotates in the same direction as previously so that the liquid is discharged through the conduits 17 and 5 towards the nozzle of the front window washer 8. On the other hand, in position 16, the pump 13 rotates in the opposite direction and the liquid is discharged through line 6 to the nozzle of the rear window washer 9.
Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown but, on the contrary, covers all variants thereof.
