Abstract

"VáLVULA PNEUMáTICA E SISTEMA DE FREAGEM". A presente invenção relaciona-se principalmente a uma válvula pneumática para limitar o nível de pressão de um fluido pneumático obtido a partir de uma fonte de fluido pneumático de baixa pressão (3) por um componente pneumático (5) usando dito fluido pneumático caracterizado pelo fato de que dita válvula inclui uma carcaça (11) na qual uma saia (21) é montada de uma maneira deslizante vedante a fluidos, dita saia dividindo o interior da carcaça (11) numa primeira câmara (17) e uma segunda câmara (19), dita carcaça incluindo um primeiro orifício (13) permitindo o abastecimento da primeira câmara (17) a partir da fonte de fluido pneumático de baixa pressão (3), um segundo orifício (15) conectando a primeira câmara (17) e o componente (5) e um terceiro orifício (23) permitindo o abastecimento da segunda câmara (19) com fluido pneumático de alta pressão, a primeira câmara (17) incluindo também meios elásticos (27) para retorno da saia (21) interposta entre a saia (21) e a carcaça (11), dita saia (21) incluindo meios (3, 41) de obturação de pelo menos um orifício de conexão (13, 15) entre a fonte de vácuo (3) e o componente pneumático (5). A presente invenção aplica-se em particular à indústria automobilística. A presente invenção aplica-se principalmente à indústria que produz sistemas de freagem para veículos a motor e em particular a automóveis particulares.
