Abstract

Patente de Invenção: "VáLVULA DE COMANDO PARACOMUTAR UMA UNIDADE HIDRáULICA DE êMBOLO ECILINDRO PARA O ACIONAMENTO DE UMA PARTE DEMáQUINA OSCILANTE". A presente invenção descreve umaválvula de reversão para uma unidade hidráulica de êmbolo ecilindro para o acionamento de uma lâmina ceifeira de uma ceifeiradebulhadora automotora. Para fins de comutação da válvula decomando é previsto, no caso, um estribo de mudança movido pelaunidade hidráulica de êmbolo e cilindro que alternadamente exerceefeito sobre uma de duas válvulas de distribuição para acomutação do êmbolo da válvula. As válvulas de distribuição, nocaso, são executadas de tal modo que durante sua operaçãoprimeiro uma mola recebe tensão prévia e com uma tensão préviasuficiente, o êmbolo de válvula é solto da sua posição final retidaaté este momento, e depois, somente pela força da mola sobtensão prévia, é comutado. Este processo de comutação daválvula de uma posição final para a outra não pode serinterrompido nem por uma queda de pressão repentina, uma vezque a comutação ocorre de modo puramente mecânico somentepor meio da mola sob tensão prévia.
