Abstract
resumo ?montagem de movimento perdido em uma ponte de válvula para uso com um trem de válvula que compreende um ajustador de folga hidráulico? trata-se de um motor de combustão interna que compreende duas ou mais válvulas de motor que recebem movimentos de acionamento de válvula de uma fonte de movimento de acionamento de válvula por meio de um trem de válvula, cujo trem de válvula compreende um ajustador de folga hidráulico, um aparelho para acionamento de válvula compreende uma ponte de válvula e uma montagem de movimento perdido disposta na mesma. a montagem de movimento perdido compreende um primeiro pistão disposto em um primeiro furo de pistão formado na ponte de válvula. o primeiro pistão é configurado para se conectar operativamente com um componente do trem de válvula. um elemento de inclinação é configurado para inclinar o primeiro pistão para fora do primeiro furo de pistão com uma primeira força que é maior que uma segunda força aplicada ao primeiro pistão pelo ajustador de folga hidráulico. um limitador de trajeto é configurado para limitar o trajeto do primeiro pistão para fora do primeiro furo de pistão para não ser maior do que uma distância de movimento perdido máxima.
