Abstract

LE THERMOSTAT PRESENTE UNE DISPOSITION QUI COMPREND DES MOYENS 2, 4, 5, 6, 7 DE POSITIONNEMENT DE DISQUES BIMETALLIQUES 8, 9 DE TYPE CONNU, DISPOSES DE MANIERE A ACTIONNER PAR L'INTERMEDIAIRE D'UN ELEMENT 18 DE TRANSFERT DE MOUVEMENT DES ELEMENTS DE CONTACT 13 SUSCEPTIBLES D'ETRE ACTIONNES SEPAREMENT, A DES TEMPERATURES DIFFERENTES, VERS L'OUVERTURE OU LA FERMETURE SELON LE SENS DE COURBURE INITIAL DE CES DISQUES BIMETALLIQUES, LES ELEMENTS DE CONTACT ETANT MAINTENUS EN PLACE DANS UN CORPS 1 DE MATIERE PLASTIQUE CHOISI DE MANIERE A PRESENTER UNE CERTAINE ELASTICITE QUI PERMET D'EVITER LA PRE-TENSION ELASTIQUE DES ELEMENTS DE CONTACTS MOBILES. LE BUT EST DE FOURNIR UN THERMOSTAT A PLUSIEURS TEMPERATURES D'INTERVENTION, EN PARTICULIER A DEUX TEMPERATURES D'INTERVENTION, AYANT UNE STRUCTURE SIMPLE ET COMPACTE, SUSCEPTIBLE D'ETRE MONTE FACILEMENT ET N'EXIGEANT PAS DE REGLAGES DE TARAGE A LA SUITE DE L'ASSEMBLAGE DE SES DIFFERENTS ELEMENTS.THE THERMOSTAT PRESENTS A PROVISION WHICH INCLUDES MEANS 2, 4, 5, 6, 7 FOR POSITIONING BIMETAL DISCS 8, 9 OF KNOWN TYPE, ARRANGED IN A MANNER TO BE ACTUATED THROUGH AN ELEMENT 18 FOR TRANSFER OF MOVEMENT OF THE ELEMENTS CONTACT 13 LIKELY TO BE ACTIONED SEPARATELY, AT DIFFERENT TEMPERATURES, TOWARDS OPENING OR CLOSING ACCORDING TO THE INITIAL DIRECTION OF CURVATURE OF THESE BIMETALLIC DISCS, THE CONTACT ELEMENTS BEING KEPT IN PLACE IN A PLASTIC MATERIAL BODY 1 WAY TO PRESENT A CERTAIN ELASTICITY WHICH PREVENTS THE ELASTIC PRE-TENSION OF THE MOBILE CONTACT ELEMENTS. THE GOAL IS TO PROVIDE A THERMOSTAT WITH SEVERAL INTERVENTION TEMPERATURES, IN PARTICULAR TWO INTERVENTION TEMPERATURES, HAVING A SIMPLE AND COMPACT STRUCTURE, LIKELY TO BE EASILY MOUNTED AND NOT REQUIRING TARGET ADJUSTMENTS FOLLOWING L 'ASSEMBLY OF ITS DIFFERENT ELEMENTS.
