Title (EN) UNIT FOR AUTOMATICALLY BLEEDING OFF THE WATER WHICH SEPARATES IN A VEHICLE FUEL FILTER, IN PARTICULAR FOR DIESEL ENGINES
(FR) UNITE DE PURGE AUTOMATIQUE D'EAU SE SEPARANT DANS UN FILTRE A COMBUSTIBLE DE VEHICULE, EN PARTICULIER DESTINE AUX MOTEURS DIESELS
Abstract:
(EN) The unit comprises a sensor means (20) positioned in the collection chamber (15) to undergo activation when the water level reaches a predetermined maximum value; there is also provided an electrically operated withdrawal device (30) connected to the vehicle electrical system, to withdraw the water separated within the collection chamber through the bleed outlet (19), or to close said outlet; a microprocessor (40) is also provided, connected to said sensor means (20) and to the switch means (50) of the vehicle electrical power system, to electrically power the withdrawal device (30) when the sensor means (20) is activated and the ignition key (51) is in a first activation position (I).
(FR) La présente invention concerne une unité comprenant un capteur (20) positionné dans le collecteur (15) qui entre en action lorsque le niveau d'eau atteint une valeur maximale prédéterminée. L'unité comprend aussi un dispositif de soutirage (30) actionné électriquement, relié au système électrique du véhicule, destiné à éliminer l'eau, séparée dans le collecteur, via une sortie de purge (19), ou bien à fermer cette sortie. Un microprocesseur (40) est relié au capteur (20) et au commutateur (50) du système d'alimentation électrique du véhicule, afin d'alimenter en électricité le dispositif de soutirage (30) lorsque le capteur (20) est activé et que la clé de démarrage (51) se trouve dans une position de première activation (I).
