Abstract

UNA SERVOVALVULA PARA UNA TOBERA DE INYECCION, EN PARTICULAR PARA SISTEMA DE RAIL COMUN, CONTIENE UNA CARCASA CON UNA CAMARA (40) DE VALVULA, UNA ABERTURA (44) DE ALTA PRESION, UNA ABERTURA (38) DE UNION, Y UNA ABERTURA (50) DE RETORNO. EN LA CAMARA DE VALVULA ES MOVIL UN MIEMBRO (52) DE VALVULA, QUE ES APLICABLE POR MEDIO DE UN DISPOSITIVO DE ACCIONAMIENTO A ELECCION EN UN PRIMER ASIENTO O EN SEGUNDO ASIENTO, DONDE EL MIEMBRO DE VALVULA EN COLOCACION EN EL PRIMER ASIENTO CIERRA LA ABERTURA (50) DE RETORNO Y LA ABERTURA (44) DE ALTA PRESION SE UNE CON LA ABERTURA (38) DE UNION Y EN LA POSICION EN EL SEGUNDO ASIENTO CIERRA LA ABERTURA (44) DE ALTA PRESION Y LA ABERTURA (38) DE UNION SE UNE CON LA ABERTURA (50) DE RETORNO. LA ABERTURA (38) DE UNION SE UNE CON UNA CAMARA (32) DE TRABAJO DE LA TOBERA DE INYECCION, CUYA TOBERA SE DISPONE CERRADA CON LA CAMARA DE TRABAJO IMPULSADA CON ALTA PRESION Y SE ABRE CON CAIDA DE PRESION EN LA CAMARA DE TRABAJO. EL DISPOSITIVO DE ACCIONAMIENTO CONTIENE UNCOMPONENTE CONFIGURADO DE FORMA VENTAJOSA COMO PIEZOACTUADOR (54), QUE SE UNE A TRAVES DE UN MIEMBRO (56) DE ACCIONAMIENTO POR MEDIO DE LA ABERTURA DE RETORNO CON EL MIEMBRO DE VALVULA.
