Abstract

DISPOSITIVO INYECTOR ELECTROMAGNETICO DEL TIPO DE PRESION-TIEMPO PARA UN MOTOR CON INYECCION.CONSTA DE UNA BOMBA COMBUSTIBLE DE ALTA PRESION REGULADA (2) Y DE UN INYECTOR ASISTIDO, QUE LLEVA UNA AGUJA DE INYECCION DE APERTURA (9). DICHA APERTURA ES POR EFECTO DIFERENCIAL DE PRESION Y CIERRE POR CALIBRADOR DE RESORTE (8), COMBINADO CON UN PISTON HIDRAULICO DE CARGA (6). EL PISTON ES DE DOBLE EFECTO, CON SU CAMARA DE CARGA (5) COMUNICADA CONSTANTEMENTE CON LA DE ALTA PRESION (4) Y SU CAMARA DE DESCARGA (13) COMUNICADA A UNA PRESION VARIABLE. DICHA PRESIONMANDADA POR UNA ELECTROVALVULA DE TRES VIAS (11) ES ACCIONADA POR UN REGULADOR ELECTRONICO (3). PONE EN COMUNICACION LA CAMARA DE DESCARGA (13) ALTERNATIVAMENTE CON LA DE LA ALTA PRESION (1) Y CON LA DE DESCARGA (12).TIENE APLICACIONES EN LOS MOTORES DIESEL INYECTADOS, EN LOS QUE SE NECESITE ALTAS PRESIONES DE INYECCION.
