Abstract

UN MONTAJE DE VALVULAS DE CONTROL DE SERVODIRECCION CONSTA DE ELEMENTOS DE VALVULA EXTERIORES E INTERIORES Y DE UN MONTAJE TRANSMISOR DE FUERZAS QUE RESISTE A LA ROTACION RELATIVA ENTRE LOS ELEMENTOS DE VALVULA. EL MONTAJE TRANSMISOR DE FUERZAS CONSTA DE UN ELEMENTO DE REACCION SUPERIOR QUE ESTA CONECTADO AL ELEMENTO DE VALVULA INTERIOR, UN ELEMENTO DE REACCION INFERIOR QUE ESTA CONECTADO AL ELEMENTO DE VALVULA EXTERIOR Y VARIOS ELEMENTOS TRANSMISORES DE FUERZA CON BOLAS COLOCADOS ENTRE LOS ELEMENTOS DE REACCION SUPERIOR E INFERIOR. LAS BOLAS ENGANCHAN UNAS RANURAS FORMADAS EN EL ELEMENTO DE REACCION INFERIOR. EN UNA PUESTA EN PRACTICA DE LA INVENCION, SOLO SE UTILIZAN TRES BOLAS. EL EQUILIBRIO HIDRAULICO Y METALICO DE LA VALVULA DE CONTROL DE SERVODIRECCION SE CONSIGUE EQUILIBRANDO HIDRAULICAMENTE LOS ELEMENTOS DE VALVULA EXTERIOR E INTERIOR ANTES DE CONECTAR EL ELEMENTO DE REACCION INFERIOR AL ELEMENTO DE VALVULA EXTERIOR. ASI, EL ELEMENTO DE REACCION INFERIOR QUEDA COLOCADO DE MANERA POCO APRETADA RESPECTO AL ELEMENTO DE VALVULA EXTERIOR. EL ELEMENTO DE REACCION SUPERIOR EMPUJA LAS BOLAS HACIA EL ELEMENTO DE REACCION INFERIOR PARA COLOCAR DE MANERA PRECISA EL ELEMENTO DE REACCION INFERIOR RESPECTO AL ELEMENTO DE VALVULA INTERIOR. EL ELEMENTO DE VALVULA EXTERIOR Y EL ELEMENTO DE REACCION INFERIOR SE INTERCONECTAN ENTONCES MEDIANTE LA DEFORMACION DE UNA PARTE DEL ELEMENTO DE VALVULA EXTERIOR.
