A device for control of turn of the shafts of valve distributors of large hydraulic presses comprises a toothed sector that is rigidly fit by means of a dowel to distribution shaft (of beam or cam type), and a toothed rack, at that two drive cylinders of piston type are placed coaxially in one continuous body above which the toothed rack is installed, at that the piston is arranged jointly with two rods, and is fixed without possibility of motion in the side parts of the bearing frame, and the driving effect on the distribution shaft is transferred from the movable body. |
