Abstract

MOTOR DE COMBUSTãO INTERNA COM SISTEMA DE VARIAçãO DE ABERTURA DE VáLVULA E VEìCULO EQUIPADO COM TAL MOTOR. Um motor endotérmico compreendendo: uma pluralidade de câmaras de combustão cada uma dotada de pelo menos uma válvula e uma alavanca (11) adaptada para gerar a abertura da referida válvula; um eixo de comando de válvulas (1) com uma pluralidade de câmeras adaptadas para controlar as referidas alavancas; uma cabeça de cilindro tendo um eixo de suporte (2), em que uma pluralidade de buchas (16, 16'), cada uma dos quais suporta, de forma rotacionável, uma das referidas alavancas, é montada de forma rotacionável e excêntrica; um atuador (8) adaptado para fazer com que a rotação das referidas buchas por um ângulo pré-determinado; caracterizado pelo fato de que as referidas buchas são feitas integradas uma à outra em rotação em torno do referido eixo de suporte, através de uma placa (12) rigidamente ligada, pelo menos, na direção de rotação.
