Abstract

"IMPULSIONADOR PARA ADAPTAR PRESSãO DE MOLA PNEUMáTICA PARA ABSORVEDOR DE CHOQUE FDD". Um sistema de suspensão para um veículo inclui um absorvedor de choque amortecedor dependente da freqüência (FDD) que define uma primeira câmara de trabalho pressurizada. Um conjunto de mola pneumática define uma segunda câmara de trabalho pressurizada. Um impulsionador permite comunicação de pressão entre a primeira câmara de trabalho pressurizada e a segunda câmara de trabalho pressurizada.
