Abstract

AMORTECEDOR PROPORCIONAL DE PRESSãO DE AR PARA ABSORVERDOR DE CHOQUE Trata-se de um amortecedor proporcional de pressão de ar que inclui uma primeira câmara e uma segunda câmara. A primeira câmara está fluidicamente fixada à segunda câmara através de uma válvula de ajuste de ar. A válvula de ajuste de ar regula o fluxo da primeira câmara para a segunda câmara em proporção à pressão de ar recebida de uma mola de ar de acompanhamento.
