Abstract

"COMPRESSOR ROTATIVO". Em um compressor rotativo para executar o suprimento de óleo aos rolamentos (32, 34, 45) através de uma passagem de suprimento de óleo principal (51) formada em um eixo de transmissão (17) empregando o diferencial de pressão entre a pressão de nível elevado e a pressão de baixo nível no invólucro (10), as partes vedantes (65) que têm uma estrutura à prova de ar são formadas em ambos os lados na direção do eixo de cada uma das faces deslizantes constituídas entre o eixo de transmissão (17) e os rolamentos (32, 34, 45), colocando as passagens de suprimento de óleo da parte de rolamento (59, 60, 61) entre a parte vedante (65), para aumentar a confiabilidade dos rolamentos (32, 34, 45) por impedimento da passagem de gás de alta pressão no espaço entre o eixo de transmissão (17) e os rolamentos (32 , 34, 45).
