Abstract

"VáLVULA CONTROLADA PREVIAMENTE, COM UMA DISPOSIçãO DE SEDE DE VáLVULA". A invenção refere-se a uma válvula controlada previamente, especialmente uma válvula de regulação eletropneumática para um sistema de freio de ar comprimido de um veículo, com uma caixa da válvula (1), que contém um êmbolo de comando (5), regulável axialmente, o qual, para a regulação axial, pode ser solicitado por meio de pelo menos uma válvula eletromagnética controlada previamente (6). O êmbolo mencionado está previsto para o acionamento de uma disposição de sede de válvula, que liga o fluxo de ar comprimido entre pelo menos uma conexão de tubulação do freio externa (15), uma conexão de pressão de alimentação, assim como uma conexão de ventilação (17). A disposição de sede de válvula (9) mencionada consiste em essência em uma guarnição de vedação em forma de vaso (12), com uma abertura coaxial (23), cuja superfície de vedação em forma de anel circular (13), corresponde com uma disposição de sede da válvula coaxial, formada de uma sede da válvula externa (11), e uma sede da válvula interna (10). A guarnição de vedação (12) apresenta uma camada intermediária de reforço interna (24), configurada em termos de corte transversal marginal em essência em forma de U. A camada mencionada está provida com uma parte saliente (25), direcionada radialmente para dentro e que reforça a região radial interna da superfície de vedação (13). As duas abas (26, 27), da camada intermediária de reforço (24), projetam-se como reforço para dentro de seções de lábio de vedação associadas(20, 21), da guarnição de vedação (12).
