Abstract

"SISTEMA ATUADOR DE VáLVULAS DE PISTõES ESCRAVOS MúLTIPLOS". Sistemas e processos de atuação de válvulas de motores, usando um sistema atuador de válvulas hidráulico, são descritos. O sistema atuador de válvulas inclui um pistão mestre e dois pistões escravos dispostos deslizantemente em furos proporcionados em um alojamento. O pistão mestre e os dois pistões escravos são conectados entre ele por um circuito hidráulico. O movimento linear, conferido ao pistão mestre, é transferido para os dois pistões escravos, por meio do circuito hidráulico. Por sua vez, os dois pistões escravos podem atuar uma ou mais válvulas do motor, diretamente ou por meio de uma ponte de válvulas intermediária. Um dispositivo de assentamento de válvulas pode ser proporcionado para auxiliar no assentamento das válvulas do motor em modalidades nas quais o sistema atuador de válvulas é adaptado para proporcionar atuação das válvulas variável.
