Abstract

"CILINDRO PRINCIPAL COMPREENDENDO UMA VEDAçãO E UM VEDADOR DE REABASTECIMENTO". Configurando um cilindro principal de freio (10) para um veículo a motor, do tipo que compreende uma estrutura essencialmente axial (12) dentro de um furo (14) que é montado capaz de ser deslizado em, pelo menos, um pistão axial (16,18), do tipo em que o furo (14) compreende dois dispositivos de vedação, dianteiros (26,28) e posteriores (30,32), que são interpostos entre o pistão (16,18) e o furo (14), os dispositivos de vedação dianteiros (26,28) que delimitam, no furo (14), as câmaras dianteiras (36 ,40) e de abastecimento posterior (34,38), do tipo em que a estrutura (12) compreende um ducto de abastecimento (42,48) que se liga em um reservatório externo na câmara de abastecimento posterior (34,38) e que se abre entre os dois dispositivos de vedação (26,28,30,32), caracterizado pelo fato de que os dispositivos de vedação dianteiros (24,28) compreendem um vedador dianteiro (26,28) que é montado em um sulco (110,112) da estrutura (12), e do qual um bocal interno, combinado em contato com o pistão (16,18), é capaz de levantar o pistão (16,18) quando o mesmo retorna de uma posição de aplicação em uma posição de repouso para o reabastecimento da câmara de pressão dianteira (36,40) com o fluído hidráulico.
