Abstract

"AMORTECEDOR SENSìVEL PARA AMORTECEDORES DE AUTOMóVEIS". Um absorvedor de choque tendo um par de conjuntos de válvula que incluem uma válvula de aceleração sensível que acopla a câmara de trabalho do absorvedor de choque para a câmara de reserva do absorvedor através do trajeto de fluido para prover uma característica de amortecimento suave para o choque quando o absorvedor de choque experimenta uma aceleração além de uma quantidade específica. Um conjunto de válvula de compressão e um conjunto de válvula de rechaço também são providos, o que controla o fluxo de fluido através do pistão e do conjunto de base, respectivamente, para prover uma característica de amortecimento firme para o absorvedor de choque durante o movimento de baixa aceleração.
