Abstract

"CONJUNTO DE VEDAçãO DE BOMBEAMENTO REVERSO E CONJUNTO DE MáQUINA". Um conjunto de vedação de bombeamento reverso (16) inclui uma vedação separadora (18) e um anel de encosto (20). A vedação separadora (18) tem faces de vedação interna, externa, dianteira e traseira. A vedação separadora (28) adicionalmente tem uma parte de face perfilada embutida e se estendendo para dentro das faces de vedação interna e traseira. A face perfilada define um canal de vedação traseiro (54). O anel de encosto (20) é posicionado no canal de vedação traseiro da vedação separadora (18). A primeira face dirigida no sentido de canal do anel de encosto (30) é configurada para limitar o deslocamento de uma parte adjacente da vedação separadora (18).
