Abstract

LA INVENCION SE REFIERE A UN APARATO DE INYECCION DE COMBUSTIBLE QUE CONSTA DE UNA VALVULA PILOTO (19) MONTADA PARA QUE CONTROLE EL PASO DEL COMBUSTIBLE A TRAVES DE UNA APERTURA DE DESCARGA (20) QUE SE COMUNICA CON UNA CAMARA DE CONTROL (9). EL COMBUSTIBLE ES SUMINISTRADO BAJO PRESION EN LA CAMARA DE CONTROL (19) Y SALE A TRAVES DE LA APERTURA DE DESCARGA (20) PARA CONTROLAR LA APERTURA DE UNA AGUJA OBTURADORA (6) CON EL FIN DE INYECTAR UNA CANTIDAD SUFICIENTE DE COMBUSTIBLE A TRAVES DE POR LO MENOS UN ORIFICIO DE INYECCION (4). LA PARTE SUPERIOR DE UN CUERPO DE LA VALVULA (14) ES DELIMITADA POR UNA SUPERFICIE PLANA (14A) EN LA QUE SE ABRE LA APERTURA DE DESCARGA (20) Y UN ANILLO ROSCADO (8) PRESIONA LA SUPERFICIE PLANA (14A) DE TAL MANERA QUE FIJA EL CUERPO DE LA VALVULA (14) AL CUERPO (1) DEL APARATO DE INYECCION DE COMBUSTIBLE.
