Abstract

"MéTODO E DISPOSITIVO DE CONTROLE DE UMA UNIDADE ELETRO-HIDRáULICA PARA ACIONAMENTO DAS VáLVULAS DE UM MOTOR ENDOTéRMICO". Método de controle de uma unidade eletro-hidráulica (1) para acionamento das válvulas (2) de um motor endotérmico (M), sendo a unidade eletro-hidráulica (1) provida de um acionador hidráulico (17) para abertura da respectiva válvula (2) com líquido pressurizado e a mola (29 ) que atua de forma oposta ao acionador hidráulico (17) para fechar a válvula (2), provê o controle do tempo de conexão (tspo; tspc; tspoc) entre o acionador hidráulico (17) e uma primeira ramificação (9) contendo o líquido pressurizado em função de um tempo predeterminado (t~ abertura~; t~ fechamento~; toc) característico da unidade eletro-hidráulica (1).
