Abstract

"DISPOSITIVO DE LEVANTAMENTO DE VáLVULA DE MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a um dispositivo de levantamento de válvula variável de um motor de combustão interna no qual um primeiro braço de ligação (58) sustentado girável em uma posição fixa de um corpo do motor está conectado girável em um balancim (31), e um eixo de suporte móvel (60) que sustenta girável uma porção de extremidade de um segundo braço de ligação (59) do qual a outra porção de extremidade conectável girável no balancim (31) está conectada em um membro de manivela (61) formado em uma forma de manivela que tem braços de manivela (61 a) sanduichando o segundo braço de ligação (59) de lados opostos, e uma parte de conexão (61c) que une integralmente ambos os braços de manivela (61a) em uma posição onde uma interferência com o segundo braço de ligação (59) é evitada. O membro de manivela (61) é rotacionalmente acionado com um meio de acionamento. Assim, a quantidade de levantamento de uma válvula de motor é continuamente mudada, em adição ao qual, uma rigidez torcional do membro de manivela é assegurada enquanto assegurando uma funcionalidade de montagem do segundo braço de ligação no membro de manivela, e a redução no tamanho é tornada possível.
