Abstract

LA INVENCION CONCIERNE A UN DISPOSITIVO DE CONTROL PARA LA VALVULA DE UN CILINDRO CON UN DEPOSITO (26) ASOCIADO CON UNA CAMARA DE PRESION (19) EN EL IMPULSOR DE VALVULA, TENIENDO EL DEPOSITO UN PISTON (23) QUE ACTUA TAMBIEN COMO UNA VALVULA PARA SEPARAR EL DEPOSITO (26) DE LA CAMARA DE PRESION (19). EL PISTON (23) PUEDE DESPLAZARSE, POR MEDIO DE UN DISPOSITIVO DE CONTROL HIDRAULICO (37, 38, 39) FUNCIONANDO EN CONJUNCION CON UNA VALVULA MAGNETICA (36), DESDE SU POSICION DE DESCANSO A UN MODO DE DEPOSITO. ESTO PERMITE A VARIAS UNIDADES DE VALVULAS DE CONTROL EN UN MOTOR, SER CONTROLADAS MEDIANTE UNA SOLA VALVULA MAGNETICA (36), PREVIENDO PARA QUE SUS TIEMPOS DE CONTROL NO SE SOBREPASEN.
