Abstract

"SISTEMA E MéTODO PARA PREVENçãO DE COLISãO PISTãO-VáLVULA EM UM MOTOR DE COMBUSTãO INTERNA". A presente invenção se refere a um sistema e a um método de acionamento de válvula para utilização em um motor de combustão interna compreendendo pelo menos um cilindro de combustão possuindo um pistão e uma válvula de motor para prevenção de colisão pistão-válvula no referido motor de combustão interna. Em concordância com a presente invenção, o referido sistema de acionamento de válvula está caracterizado pelo fato de que inclui uma bomba hidráulica, um reservatório de alta pressão, e um acionador de válvula eletro-hidráulico. A bomba hidráulica está configurada para produzir uma saída hidráulica fundamentada sobre um perfil de folga de válvula-pistão de pelo menos um cilindro do referido motor de combustão interna. O reservatório de alta pressão está acoplado com a referida bomba hidráulica. O acionador de válvula eletro-hidráulico está acoplado com o referido reservatório de alta pressão por intermédio de uma primeira válvula de controle e configurado para acionar pelo menos uma válvula de motor de referido motor de combustão interna em concordância com uma saída da referida bomba hidráulica.
