Abstract

"VEDAçãO DE LáMINA UNITáRIA PARA UM êMBOLO CEGO DE CISALHAMENTO EM UM ELEMENTO DE PREVENçãO DE EXPLOSãO TIPO êMBOLO". A presente invenção refere-se a uma vedação de lâmina unitária para um êmbolo cego de cisalhamento de um elemento de prevenção de explosão tipo êmbolo que inclui um elemento alongado possuindo uma seção transversal geralmente semicircular com uma superfície superior curva e uma superfície inferior. A superfície inferior possui um par de lados de extensão lateral que afunilam para fora e possuem uma tampa externa metálica unida aos mesmos. As tampas externas metálicas formam um ângulo agudo que engata um sulco complementar formado no êmbolo superior do conjunto de êmbolo cego de cisalhamento.
