Abstract

Sistema di sbarramento per l'olio di lubrificazione dei cuscini di un compressore centrifugo con tenute a labirinti installato in ambiente confinato, costituito da un disco solidale concentricamente all'albero ruotante del compressore nella camera prospiciente il cuscino situato lato aspirazione del compressore, tra il detto cuscino e la relativa tenuta a labirinti, il quale disco presenta una bordatura ad U rovesciato in cui è contenuto un anello statorico solidale alla parete della detta camera e disposto concentricamente all'albero, il quale forma con il detto disco un piccolo meato che viene continuamente alimentato e tenuto pieno per affetto centrifugo del detto disco ruotante, con olio di sbarramento spillato dall'olio di lubrificazione, detto anello statorico essendo inoltre provvisto, nella parte affacciata al disco, di un cuneo inserentesi in una corrispondente cavità del disco nonchè di un dente deflettore anulare sopravvanzante il bordo esterno di detta cavità del disco stesso.
