Abstract

Il dispositivo (1) è utilizzabile per realizzare la tenuta idraulica tra un albero rotante (9) ed una sede (8) fissa. Esso comprende un elemento anulare (5) scorrevole assialmente all'albero (9), supportante dei labbri di tenuta (13) ed interposto tra un elemento anulare di battuta (6) solidale all'albero (9) ed un elemento anulare fisso (4) solidale alla sede (8).I labbri di tenuta (13) definiscono rispetto all'elemento anulare di battuta (6) una camera anulare di tenuta (14) collegata con una sorgente di pressione idraulica.L'elemento anulare scorrevole (5) definisce rispetto all'elemento anulare fisso (4) una camera anulare di scorrimento (11) anch'essa collegata ad una sorgente di pressione idraulica. La tenuta è ottenuta fornendo pressioni idrauliche modulate alla camera anulare di tenuta (14) ed alla camera anulare di scorrimento (11).The device (1) can be used to create the hydraulic seal between a rotating shaft (9) and a fixed seat (8). It comprises an annular element (5) sliding axially to the shaft (9), supporting the sealing lips (13) and interposed between an annular stop element (6) integral with the shaft (9) and a fixed annular element (4 ) integral with the seat (8). The sealing lips (13) define with respect to the annular abutment element (6) an annular sealing chamber (14) connected with a source of hydraulic pressure. The sliding annular element (5) with respect to the fixed annular element (4), it defines an annular sliding chamber (11) also connected to a source of hydraulic pressure. The seal is obtained by providing modulated hydraulic pressures to the annular sealing chamber (14) and to the annular sliding chamber (11).
