Abstract

"êMBOLO PARA UM MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a um êmbolo (1) para um motor de combustão interna com furos do pino (5,6) onde são trabalhadas ranhuras de lubrificação (8,9) perimetrais acima das suas áreas de nadir e equatoriais. Para simplificar a fabricação dos furos dos pinos (5, 6) dotados das ranhuras de lubrificação (8, 9), as ranhuras de lubrificação (8, 9) possuem cada vez uma área central (10, 10<39>) cujo fundo de ranhura possui uma profundidade inferior a 100<109>m, e que em direção do lado interno e do lado externo do êmbolo é seguida por áreas de ranhuras (13, 13<39>; 15, 15<39> cujo fundo de ranhura é inclinado diagonalmente em direção ao eixo longitudinal (12) e que com a direção longitudinal do furo do pino (5, 6) formam cada vez um ângulo agudo.
