Abstract

"DISPOSITIVO DE COMPENSAçãO DE PRESSãO PARA UMA CARCAçA DE MANCAIS". A invenção refere-se a um dispositivo de compensação de pressão (4) para uma carcaça de mancais, que incorpora um compartimento hermético, e cujo dispositivo é proposto para compensar variações em pressão no compartimento hermético, em que o dispositivo (4) incorpora uma carcaça (5, 6, 7) na qual é posicionado um fole (9) de material flexível, cujo carcaça tem pelo menos uma primeira abertura (10) através da qual o interior do fole (4) comunica-se com o lado da carcaça de mancais onde pode ser prevista uma pressão variável, e em que o fole (4) é ainda associado com uma abertura adicional (8), adaptada para permitir que o fole (4) altere sua forma temporária para compensar as variações em pressão em questão.
