Abstract

"DISPOSITIVO DE OPERAçãO DE VáLVULA DE MOTOR DE COMBUSTãO INTERNA". Mecanismo característico de válvula variável que apresenta um came de operação de válvula articuladamente sustentado em um eixo de cames e um mecanismo de acionamento que oscila um mecanismo de intertravamento em torno do eixo de cames, o mecanismo de intertravamento oscilando o came de operação de válvula por meio de um came de acionamento integrado no eixo de cames. A válvula de motor começa a se abrir e a se fechar em uma porção de amortecimento do came de operação de válvula, e o mecanismo de acionamento oscila o came de operação de válvula através do mecanismo de intertravamento, controlando assim uma regulação de abertura e uma regulação de fechamento da válvula de motor. Uma porção alargada de came do came de acionamento apresenta uma porção de velocidade constante na qual uma velocidade de levantamento é constante, e a porção de velocidade constante é provida sobre uma largura angular onde a regulação de abertura em uma posição de ângulo mais avançada da regulação de abertura da válvula de motor e a regulação de abertura em uma posição de ângulo mais retardada da regulação de abertura estão incluídas.
