Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE DISTRIBUIDOR DE INYECCION DE COMBUSTIBLE DEL TIPO DE PISTON RADIAL CON DOS CILINDROS DE INTERCEPCION EN LA UNIDAD DE ROTOR Y, COLOCADO EN CADA CILINDRO, DOS PISTONES LOCALIZADOS EN CADA UNO DE LOS EXTREMOS DE LOS CILINDROS PARA DELIMITAR LOS ESPACIO (33) DE TRABAJO EN LA BOMBA. LOS PISTONES (27) EN EL PRIMER CILINDRO (25) ESTAN DISEÑADOS CON UNA LONGITUD TAL, DURANTE SU CARRERA, QUE SE PROYECTAN DENTRO DEL SEGUNDO CILINDRO (29) CUYOS PISTONES (31) NO ALCANZAN EL PRIMER CILINDRO (25) INCLUSO EN EL LIMITE DE SU CARRERA. LA INVENCION PROPONE QUE LOS PISTONES (31) CORTOS DISPONGAN DE UN TOPE EN FORMA DE UN COLLAR (43) SOBRE EL EXTREMO QUE SE PROYECTA FUERA DEL CILINDRO (29), ESTANDO DISEÑADO EL TOPE PARA PREVENIR EL DESLIZAMIENTO DE LOS PISTONES CORTOS ENTRE LOS PISTONES (27) LARGOS CUANDO LA BOMBA SE DESCONECTA, PERMITIENDO ASI QUE LA CARRERA DE LOS PISTONES SE INCREMENTE HASTA QUE LOS PISTONES (27) LARGOS EMERGEN A PARTIR DE LOS CILINDROS (29) PORTANDO LOS PISTONES (31) CORTOS DURANTE SU CARRERA DE ASPIRACION.
