Abstract

Système de freinage comportant un bloc-vannes (10) géré par une unité de commande (40), un maître-cylindre (20) alimenté par le réservoir (30) de liquide de frein. Le réservoir comporte un flotteur (51) guidé dans une cheminée (52) et portant un aimant (54) pour coopérer avec un commutateur magnéto-sensible (55) et détecter le niveau bas (Nmin) du liquide de frein dans le réservoir. L'aimant (54) est relié au fond du flotteur (51) par un support (53) descendant sous le flotteur. Le support 53 a une longueur (1) pour qu'au niveau bas (Nmin) du liquide de frein, l'aimant (54) se trouve au voisinage (54min) du fond (31) du réservoir (30) au-dessus du commutateur (55). Cette unité est installée sous le fond du réservoir dans l'axe de mouvement (xx) du flotteur et de l'aimant constituant le système de détection de niveau bas (Nmin). elle est reliée directement à l'afficheur (11) du tableau de bord (10).Braking system comprising a valve block (10) managed by a control unit (40), a master cylinder (20) supplied by the brake fluid reservoir (30). The reservoir comprises a float (51) guided in a chimney (52) and carrying a magnet (54) to cooperate with a magneto-sensitive switch (55) and to detect the low level (Nmin) of brake fluid in the reservoir. The magnet (54) is connected to the bottom of the float (51) by a support (53) descending under the float. The support 53 has a length (1) so that at the low level (Nmin) of the brake fluid, the magnet (54) is in the vicinity (54min) of the bottom (31) of the reservoir (30) above the switch (55). This unit is installed under the bottom of the tank in the axis of movement (xx) of the float and the magnet constituting the low level detection system (Nmin). it is connected directly to the display (11) of the instrument panel (10).
