A controlled deflection roll having a fixed support and a roll shell rotatable thereabout and supported upon hydraulic pressure elements delimiting a number of pressure compartments at the fixed support. A longitudinal bore extends lengthwise of the fixed support and connection bores lead therefrom to the individual pressure compartments. Pressure regulators coact with the pressure elements for setting the pressure of an hydraulic pressurized fluid medium which is infed to the individual pressure compartments. The housings of the pressure regulators and the actuation elements thereof are insertably arranged in the longitudinal bore of the fixed support and connected with a pressurized fluid medium line for the infeed of the pressurized fluid medium. Each housing has an outlet bore, the mouth of which is surrounded by a sealing region and is connectable with the connection bore of the related pressure compartment. The housing is provided with an hydraulic piston or plunger at a location opposite the sealing region, which piston sealingly closes an hydraulic pressure compartment or chamber and serves to press the sealing region of the outlet bore against the wall of the longitudinal bore of the fixed support. The hydraulic pressure chamber likewise is connected with the pressurized fluid medium line.
