Abstract

UNA VALVULA DE DISPARO ACCIONADA ELECTRICAMENTE PARA UNA BOMBA DE INYECCION DE COMBUSTIBLE QUE INCLUYE UN MIEMBRO DE VALVULA (2) ASEGURADO A UNA ARMADURA (3) PARA FORMAR UN CONJUNTO DE ARMADURA Y MIEMBRO DE VALVULA. EL MIEMBRO DE VALVULA (2) SE ENCUENTRA MONTADO DE FORMA DESLIZANTE EN UN ORIFICIO (4) Y CONTROLA LA COMUNICACION ENTRE EL ORIFICIO DE ENTRADA DE COMBUSTIBLE (5) Y EL ORIFICIO DE SALIDA DE COMBUSTIBLE (6). DURANTE SU USO, LA VALVULA SE MANTIENE EN UNA POSICION CERRADA ENERGIZANDO UNA BOBINA ESTATORICA (8) PARA ATRAER LA ARMADURA (3). CUANDO SE DESENERGIZA EL ESTATOR, UN RESORTE DE APERTURA DE LA VALVULA (10) MUEVE LOS CONJUNTOS DE ARMADURA Y MIEMBRO DE VALVULA EN LA DIRECCION DE APERTURA DE LA VALVULA. EL LARGO DEL RESORTE DE APERTURA DE LA VALVULA (10) ES TAL QUE CUANDO LA VALVULA (2) SE ENCUENTRA EN UNA POSICION TOTALMENTE ABIERTA SE FORMA UN ESPACIO (Y) ENTRE UN EXTREMO DEL RESORTE DE APERTURA (10) Y SU ASIENTO ADYACENTE (11). SEGUN ESTO, EL MOVIMIENTO INICIAL DEL CONJUNTO DEARMADURA Y MIEMBRO DE VALVULA CUANDO SE ENCUENTRA EN LA POSICION CERRADA, TRAS LA ENERGIZACION SUBSIGUIENTE DE LA BOBINA ESTATORICA (8) NO SE VE PERTURBADA POR EL RESORTE (10) HASTA QUE EL ESPACIO (Y) HAYA DESAPARECIDO DEBIDO AL MOVIMIENTO INICIAL DE LA ARMADURA (3). ESTA DISPOSICION REDUCE LA CORRIENTE ESTATORICA INICIAL NECESARIA PARA PROVOCAR EL MOVIMIENTO DEL CONJUNTO DE ARMADURA Y MIEMBRO DE VALVULA. TAMBIEN PERMITE LA UTILIZACION DE UN RESORTE DE APERTURA RELATIVAMENTE DURO (10), REDUCIENDO ASI EL IMPACTO CON QUE EL MIEMBRO DE VALVULA (2) SE ACOPLA AL ASIENTO (7) AL CERRARSE, Y GENERANDO UN MOVIMIENTO INICIAL RAPIDO EN LA DIRECCION DE APERTURA TRAS LA DESENERGIZACION DE LA BOBINA ESTATORICA (8).
