Abstract

"GAXETA METáLICA". A invenção se refere a uma gaxeta metálica tendo uma primeira linha de vedação (SL1) disposta de uma maneira e circundar a borda periférica de um orifício de gás de exaustão (3), uma segunda linha de vedação (SL2) disposta ao longo da borda periférica externa de uma placa de base (2), e rebordos cheios (6, 7) formados, cada, em uma seção transversal convexa, por meio de encurvamento da placa de base (2) ao longo de linhas de vedação. Materiais de vedação elásticos (8 a 11), cuja altura é substancialmente igual à altura de uma porção convexa dos rebordos, são fixados à porção convexa e a uma superfície plana contínua à porção convexa. O material de vedação elástico sobre a superfície plana é disposto de maneira a cobrir até à posição de embocadura de abertura do orifício de gás de exaustão (3) ou uma posição de borda periférica da placa de base (2) e, além disto, partes de material elástico (12, 13) são enchidas em uma porção cóncava do rebordo no lado reverso da porção convexa. Esta estrutura da gaxeta conduz a redução de custo e permite que a gaxeta mantenha uma estável performance de vedação por um longo período de tempo.
