Abstract

Una parte (11) de cojinete de cigüeñal tiene un par de metales (41) de cojinete principal, y el aceite lubricante se guía a partir de una galería de aceite hacia una ranura (43) para aceite circunferencial interior a través de un pasaje (33) de aceite en el bloque y un primer agujero (42) para aceite. Una cierta cantidad del aceite lubricante se suministra a una parte (17) de cojinete de eje de control por medio de un segundo agujero (44) para aceite y un pasaje (34) de aceite en la tapa. El aceite lubricante se guía a partir de un tercer agujero (46) para aceite en un par de metales (45) de cojinete de eje de control hacia una ranura (47) para aceite circunferencial interior. La ranura (43) para aceite en la parte (11) de cojinete de cigüeñal funciona también como un pasaje de aceite para suministrar el aceite lubricante a la parte (17) de cojinete de eje de control, logrando por consiguiente una configuración simple.
