Abstract
EN UN EMBOLO REFRIGERADO CON ACEITE PARA MOTORES DIESEL SE APUNTALA EN LAS SUPERFICIES (8.9) COLOCADAS UNA ENCIMA DE OTRA EL CUERPO DEL EMBOLO (2) Y LA SUPERFICIE DEL EMBOLO (5) SOBRE UNA SUPERFICIE DE SEPARACION Y SE ARRIOSTRAN UNA CON OTRA A TRAVES DE TORNILLOS (12). LAS ESCOTADURAS (15) DE FORMA DE TALADRO CIEGO QUE CORREN RADIALMENTE HACIA FUERA SE EXTIENDEN DE FORMA OBLICUA FRENTE A LA SUPERFICIE DE SEPARACION DESDE UNA CAMARA REFRIGERANTE (17) QUE SE ENCUENTRA ENTRE EL CUERPO DEL EMBOLO Y SU SUPERFICIE HASTA DENTRO DE LA ZONA COLOCADA DETRAS DEL MALLETE DE FUEGO Y DEL REBORDE DE LA SUPERFICIE DEL EMBOLO. PARA MEJORAR EL PASO DE CALOR DEL EMBOLO EN EL ACEITE REFRIGERANTE LAS ESCOTADURAS POSEEN EN SU SECCION TRANSVERSAL LA FORMA DE UN AGUJERO OBLONGO.
