Abstract

"VáLVULA FUSìVEL DE VELOCIDADE EM UM SISTEMA DE FREIO" Uma válvula fusível de velocidade aperfeiçoada controla a comunicação entre as primeira e segunda válvulas de freio e a primeira e segunda linhas de freio. A válvula fusível de velocidade inclui um alojamento de válvula tendo um furo de válvula que deslizavelmente recebe um carretel de válvula. O carretel move-se em resposta à pressão nas primeira e segunda câmaras piloto, cada uma comunicando-se com uma correspondente primeira e segunda saídas. A primeira câmara piloto comunica-se com a primeira saída via uma primeira passagem de amortecedor e um primeiro orifício e a segunda câmara piloto comunica-se com a segunda saída via uma segunda passagem de amortecedor e um segundo orifício. Os orifícios reduzem ou controlam quão rápido o carretel mover-se-á em resposta ao diferencial de pressão entre as câmaras piloto.
