Abstract

"DISPOSITIVO DE CONTROLE PARA VáLVULAS TROCADORAS DE GáS". A presente invenção refere-se a um dispositivo para o controle de válvulas trocadoras de gás de um motor de combustão interna, possuindo respectivamente atuadores de válvula (11) hidráulicos conjugados a respectivamente uma válvula trocadora de gás que respectivamente possuem um êmbolo de ajuste (13) agindo sobre a válvula trocadora de gás, e duas câmaras de trabalho (121, 122) hidráulicas delimitadas pelo êmbolo de ajuste (13), das quais a primeira câmara de trabalho (121) que solicita a válvula trocadora de gás (10) em direção de fechamento é permanentemente cheia com um fluido sob pressão, e que a segunda câmara de trabalho (122) que solicita a válvula trocadora de gás (10) em direção da abertura pode ser preenchida e descarregada seletivamente com um fluido sob pressão através de uma primeira e uma segunda válvula de comando elétrica (24, 25 ou 26, 27). Visando a redução de custos, respectivamente dois atuadores de válvula (11) são ativados alternadamente pela mesma primeira e pela mesma segunda válvula de comando (24 ou 26, 25 ou 27), e a comutação das válvulas de comutação (24, 25 ou 26, 27) é feita durante o estado de fechamento das duas válvulas trocadoras de gás (10) operadas por estes atuadores de válvula (11). (Figura 1).
