ABSTRACT:
A differential pressure actuator includes two fluid containing bags mounted on opposite sides of a support bar, and one of the bags is coupled to a load by means of a plate at the side of the bag opposite the bar. The other bag is also coupled to the load by means of a second plate mounted at the opposite end of the other bag, and the second plate is mechanically connected to the first plate by rods. Both of the bags contained a pressurized fluid in excess of atmospheric pressure, and the difference in the forces generated by the two bags is impressed upon the load. The load is a movable roller in a ringer for coating steel, and the movable roller is provided with separate actuators at opposite ends of the roller.
