Abstract

resumo patente da invenção: "vedação com charneira curva com superfície intermediária escalonada" a presente invenção refere-se a uma reentrância fornecida na periferia da charneira de modo que a aresta que define essa reentrância se engate em uma vedação de anel em o em uma sede para a charneira. uma área de contato reduzida da charneira na vedação de anel em o resulta em pressão aumentada sobre a área de contato real. a pressão aplicada sobre a área de contato também força uma distorção no anel em o, em que uma parte do anel em o não é contida devido à presença da reentrância que se move para fora do sulco de anel em o circundante de modo que a aresta na charneira comprima o anel em o que agora está parcialmente em e parcialmente estendendo-se de seu sulco circundante. a vedação é obtida a pressões de diferencial inferiores e o anel em o é mais bem fixado como um resultado do efeito de compressão da aresta sobre a charneira.
