Abstract

resumo ?motor? a presente invenção se refere a um primeiro balancim que inclui um rolo e um membro de pressão. o membro de pressão pressiona a válvula. um segundo balancim inclui uma sapata de deslize. quando a velocidade de rotação do motor está em a predeterminada região de baixa velocidade, o membro de pressão pressiona a válvula de acordo com a rotação do primeiro balancim. quando a velocidade de rotação do motor está em uma predeterminada região de alta velocidade, o membro de pressão pressiona a válvula de acordo com a rotação do segundo balancim. o rolo vem em contato de rolamento com o eixo de came. a sapata de deslize vem em contato de deslize com o eixo de came. a extremidade da porção de ponta da sapata de deslize é mais próxima ao eixo geométrico do eixo oscilante do que a extremidade da porção de ponta do rolo como visto a partir da direção axial do eixo oscilante. a largura máxima da sapata de deslize é maior do que a largura do rolo na direção axial do eixo oscilante.summary? engine? The present invention relates to a first rocker including a roller and a pressure member. the pressure member presses the valve. A second rocker includes a slide shoe. When the engine speed is in the predetermined low speed region, the pressure member presses the valve according to the rotation of the first rocker. When the engine speed is in a predetermined high speed region, the pressure member presses the valve according to the rotation of the second rocker. The roller comes in bearing contact with the cam shaft. The sliding shoe comes in sliding contact with the cam shaft. the tip end portion of the sliding shoe is closer to the oscillating axis geometric axis than the tip end portion of the roller as viewed from the axial direction of the oscillating axis. The maximum width of the sliding shoe is greater than the width of the roller in the axial direction of the oscillating shaft.
