Abstract

Patente de Invenção: <B>"DISPOSITIVO DE VáLVULA DE AMORTECIMENTO"<D>. A invenção refere-se a um dispositivo de válvula de amortecimento, que possibilita a sua combinação com um servomotor de uma servodireção hidráulica para constituir um amortecedor de direção. Para a compensação de variações da viscosidade do meio hidráulico em função da temperatura, os elementos de válvulas são ajustados por elementos bimetálicos.
