Abstract

Un dispositivo regolatore di livello per veicoli presenta perlomeno un cilindro di mandata (attuatore 11, 12) che è azionato con fluido in pressione ed è disposto tra carrozzeria e sospensione, una sorgente (27) del fluido in pressione ed una depressione (28) per il fluido in pressione atta ad alimentare con fluido in pressione l'attuatore (11, 12), nonché una valvola (20, 20') per la regolazione proporzionale della pressione atta a governare il flusso del fluido in pressione. La valvola (20, 20') per la regolazione proporzionale della pressione presenta una valvola principale (25) ed una valvola di regolazione, iniziale (26) per comandare il cassetto di distribuzione (30) della valvola principale in perlomeno tre posizioni del cassetto, laddove nelle posizioni intermedie del cassetto le tre connessioni governate (21-23) della valvola principale (25) sono intercettate. Al fine di evitare variazioni brusche della posizione della carrozzeria all'atto della messa in funzione del dispositivo regolatore di livello, da un lato nella tubazione (16, 16') del fluido in pressione che dal cilindro di mandata (11, 12) porta alla valvola principale (25) è disposta una valvola di contropressione (19) che può essere fatta sfiorare e dall'altro la o nella valvola principale (25) è previsto un dispositivo di centraggio (70) azionato dal fluido in pressione, che fissa il cassetto di distribuzione (30), al più tardi con l'instaurarsi di una pressione per effetto della sorgente (27) del fluido in pressione, nella sua posizione intermedia e/o libera di nuovo immediatamente dopo l'apertura della valvola di contropressione (19).(Figura 3)
