Abstract

CONJUNTO DE VEDAçãO DE EIXO E COMPRESSOR INCORPORANDO O MESMO. Um conjunto de vedação de eixo para um compressor inclui um primeiro e segundo anéis de ressalto (35, 37), cada um dos quais está disposto em torno de um eixo (16) de um compressor que provê vedação. Um anel retentor (36) está disposto entre os dois anéis de ressalto, a fim de manter a forma do primeiro anel de ressalto (35), que serve para permitir o vazamento do fluido quando o eixo (16) gira e para impedir o vazamento quando o eixo (16) pára. Os três anéis (35, 36 e 37) são mantidos juntos nas partes radiais dos anéis (35b, 36a e 37e). Cada uma das partes radiais dos dois anéis de ressalto se estende na direção externa, além da parte radial do anel retentor, provendo uma área de contato anular. Os dois anéis de ressalto (35, 37) contatam de forma resiliente um ao outro, na área de contato. Uma projeção anular (43) é provida em pelo manos um dos anéis de ressalto, na área de contato, para impedir a folga dos anéis, causada pelo fluido vazado.
