Abstract

UNA TOBERA DE INYECCION DE COMBUSTIBLE (1) PARA UN MOTOR DE COMBUSTION COMPRENDE UNA AGUJA DE TOBERA (5) INSTALADA EN UN CUERPO DE TOBERA (2) DESPLAZABLE EN UNA GUIA CONTRA UN MUELLE DE CIERRE (4) QUE ACTUA DESCENTRADO, CUYA PUNTA (6) CONTROLA UNOS ORIFICIOS DE INYECCION (10, 10'', 10'''') DISTRIBUIDOS EN EL PERIMETRO DE UN ASIENTO DE VALVULA (9) PARA UNA INYECCION PREVIA Y PRINCIPAL. DE ACUERDO CON LA INVENCION SE PROPONE QUE SE SELECCIONE EL GUIADO DE LA AGUJA DE TOBERA (5) EN EL CUERPO DE TOBERA (2) EN LA DIRECCION DEL PLANO DEFINIDO POR EL EJE (5'') DE LA AGUJA DE TOBERA (5) Y EL EJE (4'') DEL MUELLE DE CIERRE (4) DESCENTRADO, CON UN HOLGURA TAL QUE SE DESPLACE LATERALMENTE POR LA ACCION DESCENTRADA DEL MUELLE LA PUNTA DE LA AGUJA DE TOBERA (5) AL COMIENZO DEL DESPLAZAMIENTO DE ELEVACION A UNA POSICION SOBRE EL ASIENTO DE LA VALVULA (9) QUE CIERRE AL MENOS UN ORIFICIO DE INYECCION (10, 10'', 10'''').
