Abstract

"SISTEMA DE ATUAçãO DE VáLVULA PARA ATUAR AS VáLVULAS DE MOTOR EM UM MOTOR DE COMBUSTãO INTERNA". é apresentado um sistema de atuação de válvula de motor de combustão interna (10). A presenta invenção proporciona um atuador hidráulico para operar uma válvula de motor (300) que inclui um elemento de controle (120) para regular a velocidade de assentamento da válvula. A presente invenção assegura o curso livre sem restrição de válvula durante a sua abertura, e um retorno sem restrição da válvula até a válvula estar dentro de uma distância predeterminada da sede de válvula. Uma vez dentro desta gama predeterminada, a velocidade de retorno da válvula do motor é limitada pela taxa à qual um fluido pode se escapar através de um estrangulamento de fluxo. O estrangulamento é calibrado para proporcionar a máxima velocidade de assentamento da válvula.
