Abstract
A controlled deflection roll comprising at least one piston-like or punch-like pressure or support element which is provided with a bearing or contact surface upon which there can slide or bear the roll shell of the controlled deflection roll. The bearing or support arrangement at the respective ends of the roll shell, is equipped with throttle disk means for limiting the infeed of a hydraulic fluid medium, typically oil, to the bearings of the bearing arrangements, from an intermediate compartment or chamber located between the roll shell and its roll support or beam. Additionally, between the bearing and an outer seal means there is arranged an outflow element, such as an outflow conduit, for the withdrawal of the oil or other hydraulic medium.
