Abstract

resumo compressor um compressor (1) impede óleo de lubrificação de vazar de uma extremidade inferior de um rolamento (3) e fluindo para fora de um revestimento (5). o compressor (1) inclui um mecanismo de compressão (7), um eixo de acionamento (11), um rolamento (3) para o eixo de acionamento (11), e uma passagem de suprimento de óleo (29) configurada para suprir óleo de lubrificação para uma folga entre o eixo de acionamento (11) e o rolamento (3). o eixo de acionamento (11) inclui uma parte do eixo de diâmetro grande (11f) suportada pelo rolamento (3), e uma parte do eixo de diâmetro pequeno (11g) conectada a uma parte de extremidade inferior da parte do eixo de diâmetro grande (11f). uma parte de vedação (10) configurada para reduzir ou impedir vazamento de óleo do rolamento (3) inclui uma superfície de recebimento de óleo (26) faceando uma superfície inclinada circular (12) formada em um limite entre a parte do eixo do diâmetro grande (11f) e a parte do eixo de diâmetro pequeno (11g) e sendo separada da superfície inclinada (12) com uma folga.
