Abstract

Una abertura (35a) en un lado extremo de un pasaje (35) de aceite de alojamiento de pasador se abre a la superficie circunferencial interior de una parte (14) de alojamiento de pasador de un acoplamiento (3) superior, mientras que una abertura (35b) en el otro lado extremo del mismo se abre a la superficie circunferencial exterior de la parte (14) de alojamiento de pasador del acoplamiento (3) superior. Un pasaje (36) de aceite de acoplamiento inferior tiene una abertura (36a) en un lado extremo estructurada para abrir a una superficie (33) que mira hacia el alojamiento de pasador del acoplamiento (2) inferior que mira hacia la superficie circunferencial exterior de la parte (14) de alojamiento de pasador del acoplamiento (3) superior y su abertura (36b) en el otro lado extremo estructurada para abrir a una superficie (37) de cojinete de muñequilla. El pasaje (36) de aceite de acoplamiento inferior se configura para apuntar, en un ángulo de manivela prescrito, a un borde extremo especificado de los bordes extremos de la abertura (35b) en el otro lado extremo del pasaje (35) de aceite de alojamiento de pasador, el borde extremo especificado que mira hacia un lado extremo del acoplamiento (3) superior.
