Abstract

INDICATEUR DE NIVEAU DE LIQUIDE, DESTINE EN PARTICULIER A INDIQUER LE NIVEAU DU CARBURANT DANS UN RESERVOIR DE VEHICULE, COMPRENANT UN FLOTTEUR 6 MUNI D'UNE OUVERTURE CENTRALE, UNE TIGE DE GUIDAGE 4 PASSANT A TRAVERS CETTE OUVERTURE, UN ENROULEMENT 5 EN FIL CONDUCTEUR PORTE PAR LA TIGE DE GUIDAGE SUR SENSIBLEMENT TOUTE SA HAUTEUR, AU MOINS UNE LAME CONDUCTRICE 7 PORTEE PAR LE FLOTTEUR ET CONSTAMMENT EN CONTACT AVEC L'ENROULEMENT, UN TUBE 1 AYANT UN FOND FIXE A L'EXTREMITE INFERIEURE DE LA TIGE DE GUIDAGE ETENTOURANT LE FLOTTEUR ET DES CONNEXIONS ELECTRIQUES RELIANT RESPECTIVEMENT LA LAME CONDUCTRICE ET L'UNE DES EXTREMITES DE L'ENROULEMENT A DES BORNES DE SORTIE. LE FLOTTEUR PORTE UN CONTACT CONSTITUE PAR UNE TIGE CONDUCTRICE 15 COULISSANT LIBREMENT DANS UN ALESAGE PRATIQUE DANS LE FLOTTEUR, LEDIT ALESAGE AYANT SON AXE SENSIBLEMENT PARALLELE A L'AXE DE LA TIGE DE GUIDAGE, LA TIGE CONDUCTRICE PORTANT UN ELEMENT DE RETENUE 22 A SON EXTREMITE SUPERIEURE, ET UNE SURFACE CONDUCTRICE 23 EST PLACEE SUR LE FOND DU TUBE, LA RENCONTRE ENTRE LA TIGE CONDUCTRICE 15 ET LA SURFACE CONDUCTRICE 23 FERMANT UN CIRCUIT D'ALERTE.LIQUID LEVEL INDICATOR, IN PARTICULAR INTENDED TO INDICATE THE FUEL LEVEL IN A VEHICLE TANK, INCLUDING A FLOAT 6 EQUIPPED WITH A CENTRAL OPENING, A GUIDING ROD 4 PASSING THROUGH THIS OPENING, A WIRE WIRE 5 BY THE GUIDE ROD ON SENSITIVELY ITS FULL HEIGHT, AT LEAST ONE CONDUCTIVE BLADE 7 CARRIED BY THE FLOAT AND CONSTANTLY IN CONTACT WITH THE WINDING, A TUBE 1 HAVING A BOTTOM FIXED AT THE LOWER END OF THE GUIDE ROD SURROUNDING THE FLOAT AND ELECTRICAL CONNECTIONS RESPECTIVELY CONNECTING THE CONDUCTIVE BLADE AND ONE OF THE ENDS OF THE WINDING TO THE OUTPUT TERMINALS. THE FLOAT MAKES A CONTACT CONSTITUTED BY A CONDUCTING ROD 15 SLIDING FREELY IN A CONVENIENT BORE IN THE FLOAT, THIS BORE HAVING ITS AXIS SENSITIVELY PARALLEL TO THE AXIS OF THE GUIDING ROD, THE CONDUCTING ROD CARRYING A RETAINING ELEMENT 22 UPPER, AND A CONDUCTIVE SURFACE 23 IS PLACED ON THE BOTTOM OF THE TUBE, THE MEETING BETWEEN THE CONDUCTIVE ROD 15 AND THE CONDUCTIVE SURFACE 23 CLOSING AN ALERT CIRCUIT.
