Abstract

La moto-pompe (11) pourvue d'un régulateur de niveau à flotteur (14) comprend au moins un aimant (15) relié au flotteur (14) qui est guidé dans ses déplacements. Cet aimant agit au moins sur un générateur Hall (16, 17) commandant le déclenchement du régulateur à travers une paroi du carter formée au moins partiellement d'un matériau paramagnétique ou diamagnétique. Pour l'enclenchement et le déclenchement, soit deux aimants (25, 26) situés sur le flotteur (24) peuvent commander un seul générateur Hall (27) disposé à l'intérieur du carter, soit un seul aimant (15) fixé au flotteur (14) peut commander deux générateurs Hall (16, 17) dans le carter. Un dispositif de commande (12, 22) comprend des premières entrées (121, 122,...) reliant les générateurs Hall et des commutateurs, notamment des commutateurs électroniques, commandés en fonction des tensions d'entrée, et d'autres entrées pour des générateurs Hall servant à des fonctions de protection et de surveillance.
