Abstract

UNA TOBERA DE INYECCION PARA UTILIZACION EN SISTEMAS DE RAIL COMUN CONTIENE UN CUERPO (26) DE TOBERA PROVISTO CON UN EMBOLO (30) ACTUADOR, QUE EN SITUACION CERRADA DE LA TOBERA DE INYECCION HACE CONTACTO EN UN ASIENTO Y LIMITA POR ENCIMA DE LA CORRIENTE DEL ASIENTO UN ESPACIO (28) DE TOBERAS QUE SE UNE CON LA CONDUCCION DE ALTA PRESION DEL SISTEMA DE RAIL COMUN, CON UN ESPACIO (32) DE TRABAJO DEL EMBOLO (30) ACTUADOR, QUE SE UNE A TRAVES DE UN ACTUADOR (34) DE AFLUENCIA CON LA CONDUCCION DE ALTA PRESION. LA SUPERFICIE ACTIVA DEL EMBOLO (30) ACTUADOR ES MAYOR QUE LA SUPERFICIE ACTIVA EN EL ESPACIO DE TOBERAS DEL CUERPO DE TOBERAS, CON UNA CONDUCCION (14) DE RETORNO QUE GUIA DESDE EL ESPACIO DE TRABAJO A TRAVES DE UNA ABERTURA DE RETORNO DE UNA VALVULA (36) DE RETORNO Y UN EQUIPO DE ACCIONAMIENTO CONTROLADO MEDIANTE SEÑAL ELECTRICA PARA ACCIONAMIENTO DEL MIEMBRO DE VALVULA DE LA VALVULA DE RETORNO. LA TOBERA DE INYECCION SE CARACTERIZA DE ACUERDO CON LA INVENCION DE TAL MODO, QUE EL EQUIPO DEACCIONAMIENTO ES EL MIEMBRO (38) DE VALVULA ANALOGICO PARA EL EQUIPO (40) QUE SE AJUSTA CON LA SEÑAL ELECTRICA, DE TAL MODO QUE LA VALVULA DE RETORNO FORMA EN SECCION TRANSVERSAL UN ESTRANGULADOR VARIABLE DE LA CONDUCCION (14) DE RETORNO. LA TOBERA DE INYECCION DE ACUERDO CON LA INVENCION SE ADAPTA EN EL DESARROLLO DE LA INYECCION DE FORMA OPTIMA A LAS NECESIDADES DE OPERACION RESPECTIVAS.
