Abstract

BOMBA MECANICA DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA, EN LA QUE LA BOMBA DE PISTON PRESENTA A AMBOS LADOS DE UNA PARTE (21) DEL PISTON CAMARAS DE TRABAJO (41, 42), QUE TIENEN UNA RELACION DE VOLUMEN DE IMPULSION DE APROXIMADAMENTE 2 : 1, DE QUE LA CAMARA DE TRABAJO (41) MAS GRANDE IMPULSA A TRAVES DE UNA VALVULA DE PRESION (49) A UN VACIADO (45), QUE ESTA UNIDO DIRECTAMENTE CON LA CAMARA DE TRABAJO (42) MAS PEQUEÑA Y A TRAVES DE OTRA VALVULA DE PRESION (50) CON UNA CONEXION DE PRESION (48) PARA UN RECEPTOR. CON LA INVENCION SE HA PODIDO CONSEGUIR UNA BOMBA DE COMBUSTIBLE COMPACTA, QUE IMPULSA CASI EXENTA DE OSCILACIONES DE PRESION.
