Abstract

SISTEMA DE ATUAÇÃO DE VÁLVULA QUE COMPREENDE COMPONENTES DE MOVIMENTO PERDIDO EM SÉRIE PARA USO NA DESATIVAÇÃO DE CILINDRO E EM ATUAÇÕES DE VÁLVULA AUXILIARES. A presente invenção se refere a um sistema de atuação de válvula que compreende uma fonte de movimento de atuação de válvula configurada para for-necer um movimento de atuação de válvula principal e um movimento de atuação de válvula auxiliar para atuar pelo menos uma válvula de motor por meio de uma trajetória de carga de atuação de válvula. Um mecanismo de subtração de movimen-to perdido é disposto na trajetória de carga de atuação de válvula e configurado, em um primeiro estado operacional padrão, para transportar pelo menos o movimento de atuação de válvula principal e configurado, em um primeiro estado ativado, para perder o movimento de atuação de válvula principal e o movimento de atuação de válvula auxiliar. Adicionalmente, um mecanismo de adição de movimento perdido configurado, em um segundo estado operacional padrão, para perder o movimento de atuação de válvula auxiliar e configurado, em um segundo estado ativado, para transportar o movimento de atuação de válvula auxiliar, sendo que o mecanismo de adição de movimento perdido está em série com o mecanismo de subtração de mo-vimento perdido na trajetória de carga de atuação de válvula pelo menos durante o segundo estado ativado.
