Abstract
Perfeccionamientos en bombas inyectoras de combustible gobernadas por cantos oblicuos para motores de combustión interna, del tipo que comprende por lo menos un émbolo de bomba accionado con carrera siempre constante y guiado móvil axialmente, así como en rotación dentro de un cilindro de bomba, que en su superficie lateral presenta un escote que está comunicado siempre con la cámara de trabajo de la bomba y que para concluir el transporte de combustible establece a través de un taladro de mando en la pared del cilindro de bomba, una comunicación entre la cámara de trabajo de la bomba y una cámara de presión más baja - preferentemente la cámara de aspiración de la bomba- y una ranura colectora de aceite de fuga en forma de ranura anular separada de este escote, la cual es comunicable con la cámara de presión más baja, a través de un canal de aceite de fuga practicado diametralmente opuesto al escote en la superficie lateral del émbolo y que se extiende en dirección al extremo del lado de lacámara de trabajo de la bomba del émbolo de bomba, y a través de un taladro de aceite de fuga en la pared del cilindro de bomba opuesta al taladro de mando, caracterizados porque el canal de aceite de fuga consta de varias ranuras de evacuación de aceite de fuga estrechas, que se comunican al menos indirectamente con la ranura colectora de aceite de fuga.
