Abstract

"DISPOSITIVO DE OPERAçãO DE VáLVULA PARA MOTOR DE COMBUSTãO INTERNA". Um dispositivo de operação de válvula para um motor de combustão interna é capaz de aumentar uma duração de sobreposição de válvula negativa quando quantidades de levantamento máximo de uma válvula de admissão e uma válvula de exaustão são pequenas. O dispositivo de operação de válvula V é fornecida com mecanismos de ajuste de característica de lado de admissão e de lado de exaustão Mi e Me para ajustar características de operação de uma válvula de admissão 7 e uma válvula de exaustão 8. Cada mecanismo de ajuste de característica Mi ou Me tem um came de controle 14 rodando integralmente com um eixo de came 13, um motor elétrico 30 que faz um detentor 15 pivotado no eixo de came 13 rodar em torno do eixo de came 13, uma subalavanca oscilante 16 pivotada no detentor 15 e feita oscilar pelo came de controle 14, e um came de válvula 18 que é feito oscilar em torno do eixo de came 13 por oscilação do detentor 15 da subalavanca oscilante 16, para causar a oscilação de alavancas oscilantes principais 10 e 11. O motor elétrico 30 faz o detentor 15 oscilar de tal maneira que a regulagem de abertura de válvula da válvula de admissão 7 é retardada quando um valor de levantamento máximo da válvula de admissão 7 se torna menor e a regulagem de fechamento de válvula da válvula de exaustão 8 é avançada quando o valor de levantamento máximo da válvula de exaustão 8 se torna menor.
