Abstract

Patente de Invenção: <B>"SISTEMA DE OPERAçãO COM VáLVULA EM UM MOTOR DE COMBUSTãO INTERNA"<D>. Em um sistema de operação com válvula em um motor de combustão interna, um dos balancins adjacentes é provido com uma primeira e uma segunda paredes de suporte, com a segunda parede de suporte disposta na lateral do outro balancim, e um rolete é disposto entre as primeira e segunda paredes de suporte, para entrar em contato de rolamento com cames. Um eixo de rolete cilíndrico, sobre o qual o rolete é suportado de forma rotativa, é provido entre as primeira e segunda paredes de suporte, de modo que um pino de alternância de um meio de alternância de operação associativa seja encaixado de forma deslizante no eixo de rolete, em resposta ao movimento do mesmo, para uma posição de operação associativa. O eixo de rolete é encaixado sob pressão em pelo menos uma segunda das primeira e segunda paredes de suporte, e uma margem de encaixe sob pressão para o eixo de rolete encaixado sob pressão na segunda parede de suporte na lateral do outro balancim é regulada menor do que uma margem de encaixe sob pressão para o eixo de rolete encaixado sob pressão na segunda parede de suporte no lado do rolete. Assim, o eixo de rolete, que suporta o rolete e guia o pino de alternância, pode ser fixado facilmente ao balancim, enquanto se evita um aumento no número de peças e um aumento no número de etapas de processamento. Mais ainda, durante o movimento dos pinos de alternância para a posição de operação associativa, a deformação de uma extremidade do eixo de rolete, que recebe o pino de alternância, devido ao encaixe sob pressão, é suprimida para um nível pequeno, desse modo suavizando o encaixe sob pressão do pino de alternância no eixo de rolete, para suavizar a operação associativa dos balancins adjacentes e a liberação da operação associativa pelo pino de alternância.
