Abstract

LA PRESENTE INVENCION DESCRIBE UN METODO PARA APLICAR A UNA VALVULA SOLENOIDE, DURANTE SU MOVIMIENTO DE CIERRE POR LA ACCION DE UN MUELLE (7), UNA SEÑAL DE VOLTAJE CUYO OBJETIVO ES FRENAR EL MOVIMIENTO DEL CIERRE. EL CIRCUITO COMPRENDE UN CONMUTADOR ESTATICO (8) CONECTADO ENTRE LA BOBINA (7A) DE LA VALVULA SOLENOIDE Y LA TIERRA, Y UNA TOMA INTERMEDIA ENTRE ESTOS DOS COMPONENTES DESDE LA QUE ES EXTRAIDA UNA SEÑAL DE VOLTAJE (VA) Y ES TRANSFORMADA POR UN MICROCONTROLADOR EN UNA SEÑAL DE CONTROL PARA EL CONMUTADOR ESTATICO (8), PARA, POR EJEMPLO, APLICAR LA SEÑAL DE FRENADO A LA VALVULA SOLENOIDE.
