Abstract

Patente de Invenção: "AMORTECEDOR DE CHOQUE VARIáVEL, CONTìNUO, ATUADO POR SOLENóIDE". Um amortecedor de choque inclui um tubo de pressão com um pistão disposto de modo a deslizar no mesmo. Uma válvula separada inclui um circuito de fluido para um fluxo de fluido em rechaço e um circuito de fluido para um fluxo de fluido em compressão. Cada circuito de fluido inclui um orifício variável que permite a seleção entre um rechaço firme com uma compressão suave, um rechaço suave com uma compressão suave, e um rechaço suave com uma compressão firme. Cada orifício variável fica em comunicação com uma válvula de descarga de tal maneira a prover um aspecto de descarga variável para as válvulas de descarga.
