Abstract

UN TRANSDUCTOR BIESTABLE CONTROLADO ELECTRONICAMENTE TIENE UNA ARMADURA (27) ENTRE DOS POSICIONES QUE INCLUYEN CADA UNA UN RESORTE TENSIONADO (11,12) O AIRE COMPRIMIDO DENTRO DE UNA CAMARA DE CIERRE EN EL TRANSDUCTOR PARA HACER QUE LA ARMADURA SE MUEVA, Y UN PESTILLO DE IMAN PERMANENETE (5,6) PARA SUJETAR LA ARMADIURA EN CADA UNA DE LAS POSICIONES. UN DISPOSITIVO ELECTROMAGNETICO (3,4) PARA NEUTRALIZAR TEMPORALMENTE EL EFECTO DEL PESTILLO IMANTADO (5,6) LIBERA LA ARMADURA (27) PARA MOVERSE DESDE UNA A OTRA POSICION. EL TRANSDUCTOR ENCUENTRA PARTICULAR UTILIDAD COMO MECANISMO DE ACCIONAMIENTO EN VALVULAS DE MOTORES DE COMBUSTION INTERNA.
