Abstract

VáLVULA DE CONTROLE DE FLUXO PARA AMORTECEDORES HIDRáULICOS DE AMORTECIMENTO VARIáVEL. O amortecedor, ao qual a válvula de controle é aplicada, é do tipo que compreende: um tubo de pressão (10) ; um pistão (14) dividindo o tubo de pressão (10) em câmaras de compressão (CC) e de tração (CT) comunicáveis entre si através do pistão (14); um reservatório (20) de fluido hidráulico, provido de uma comunicação fluida seletiva e bidirecional com a câmara de compressão (CC); e uma válvula de controle (VC) provendo uma comunicação fluida seletiva entre a câmara de tração (CT) e o reservatório (20) e compreendendo um corpo tubular (40) provido de pelo menos uma passagem radial (41) aberta para o interior do corpo tubular (40) e para o reservatório (20); um pino obturador (60) axialmente deslocável no interior do corpo tubular (40), entre uma posição de válvula de controle fechada e diferentes posições de válvula de controle (VC) aberta para comunicar a câmara de tração (CT) com o reservatório (20) ; e um meio atuador (A) para deslocar axialmente o pino obturador no interior do corpo tubular (40)
