A deflection adjusted roll includes a plurality of hydraulic support elements for a roll jacket, wherein the support elements are provided with a hydraulic pressure medium via a bore axially extending in common with the carrier as well as via further radial bores discharging into the axially extending bore, with the radial bores being in communication with the support elements and separate pressure control of the pressure medium for each support element being achieved in that each one of the radially extending bores is associated with a controllable throttling element, with the throttling element being slidably disposed within the axially extending bore and so shaped and pressed against the inside surface of the axial bore that at least one connecting gap is provided or available between the axial bore and the radial bores, whereby the through-flow quantity of the hydraulic pressure medium is controllable via the cross section of the connecting gap.
A deflection adjusted roll comprising a fixed carrier and a roll jacket, with the roll jacket being rotatable about the carrier, wherein the roll jacket is supported on a plurality of hydraulic support elements, with the support elements being provided with a hydraulic pressure medium via a bore axially extending in common with the carrier as well as via further bores, discharging into the axially extending bore, with the further bores also being in communication with at least each one of the support elements and being substantially radially extending, wherein each one of the radially extending bores is associated with a controllable throttling element, with the throttling element being slidably disposed within the axially extending bore of the carrier, for influencing the flow-through of the pressure medium, with the throttling elements being so shaped being are pressed, via at least one biasing element each, against an inside surface of the axially extending bore, so that at least one connecting gap, for the pressure medium, between each of the radially extending bores and the axially extending bore, is one of being provided and created via a plurality of first elements arranged in the axially extending bore, and wherein at least the cross section of the connecting gap, between the throttling element and the axial bore is controllable via one of the plurality of first elements and a plurality of additional elements also located in the axially extending bore.
