Abstract

UNA TOBERA DE INYECCION DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA TIENE UNA VALVULA DESLIZABLE EN UN VACIO DENTRO DEL CUERPO DE UNA VALVULA VALVULA DESLIZABLE EN UN VACIO DENTRO DEL CUERPO DE UNA VALVULA. UNA PRIMERA PARTE VACIO (12) EN LA QUE UNA PARTE DE LA PRIMERA VALVULA ES UN AJUSTE DESLIZABLE INCOMUNICADO QUE SE EXTIENDE DESDE UNA CARA FINAL (8) DEL CUERPO (1). LA PRIMERA PARTE VACIA (12) ESTA CONECTADA POR UNA RANURA ANULAR EN LA PARED DEL VACIO, FORMANDO UNA PARTE VACIA CON MUESCAS, A UNA SEGUNDA PARTE VACIA (15) QUE RODEA UNA PARTE DE LA VALVULA DE DIAMETRO REDUCIDO, CUYO FINAL SE ASIENTA EN LA ZONA CERRADA DE LA TOBERA EN UN ASIENTO DE LA VALVULA (18) FORMADO EN EL CUERPO DE LA TOBERA (1). ESTO IMPIDE EL ACCESO DE COMBUSTIBLE DESDE LA PARTE VACIA CON MUESCAS (13) A TRAVES DE LA SEGUNDA PARTE VACIA CON MUESCAS (15) A UNO O MAS ORIFICIOS DE PULVERIZACION (20) FORMADOS EN UN EXTREMO (5) DEL CUERPO DE LA TOBERA. UN CANAL DE ABASTECIMIENTO DE COMBUSTIBLE (24) SE EXTIENDE DESDELA CARA EXTERIOR DEL CUERPO DENTRO DE LA PARED DEL CUERPO Y CRUZA UNA EXTENSION EXCENTRICA (26) QUE SE EXTIENDE DESDE LA PARTE VACIA CON MUESCAS (12) PARA EL ABASTECIMIENTO DE COMBUSTIBLE A ESA ZONA, LA INTERSECCION INCLUYE LA PARTE DE LA EXTENSION EXCENTRICA MAS CERCANA A LA CARA DEL EXTREMO (8).
