Abstract
controle de ajustador de folga em sistemas de atuação de válvula de motor. trata-se de sistemas para a atuação de válvula em motores de combustão interna que fornecem configurações para ajustadores de folga hidráulicos e componentes de trem de válvulas da atuação de válvula que são particularmente adequados para a prevenção de elevação do hla em ambientes de cames dedicados, incluindo arquiteturas de trem de válvulas de tipo ii. em uma implementação, um componente de carregamento do ajustador de folga, que pode compreender um pistão polarizado por mola de curso limitado associado ao trem de válvulas de evento principal, mantém o ajustador de folga sob uma força de compressão constante para prevenir a elevação.
