Abstract

"VEDAçãO DE REBORDO POSSUINDO FORçA DE CONTATO AUMENTADA EM INTERFACE E APARELHO INCORPORANDO A MESMA". A invenção refere-se a uma vedação tendo uma parte de corpo, pelo menos uma parte de rebordo se estendendo a partir da parte de corpo, e uma protuberância formada na pelo menos uma parte de rebordo. A parte de rebordo e protuberância formadas na mesma podem incluir um segmento arqueado em que o segmento arqueado da protuberância exibe um raio menor que o segmento arqueado da parte de rebordo. A protuberância ainda inclui uma superfície ou um segmento juntando seu segmento arqueado no lado de fluido pretendido ou a montante da vedação. O segmento da protuberância no lado de fluido pretendido pode ser configurado para ser substancialmente perpendicular com a superfície de um elemento de máquina com o qual entra em contato. A configuração e orientação da protuberância permite a vedação aplicar uma força de contato aumentada sobre uma área reduzida, aperfeiçoando a penetração de uma película fluida formada na superfície do elemento de máquina e desse modo reduzindo o vazamento.
