Abstract

"UNIDADE ELETRO-HIDRáULICA PARA ACIONAMENTO DAS VáLVULAS DE UM MOTOR ENDOTéRMICO". Uma unidade eletro-hidráulica (1) para acionamento das válvulas 2) de um motor endotérmico (M) provida de um acionador hidráulico (17) para levantamento de uma respectiva válvula (2) através de um líquido pressurizado e uma mola (29) que atua de forma oposta ao acionador hidráulico (17) para fechar a válvula (2) e descarregar o líquido do acionador hidráulico (17) na fase final de fechamento da válvula (2) através da ramificação de descarga (21; 48) provida de um orifício calibrado (22; 49) para reduzir a velocidade de expulsão do líquido e manter uma velocidade de fechamento da válvula (2) substancialmente constante durante a descarga do líquido a partir do acionador hidráulico (17).
