Telescopic cylinder with variable volume feed channels and cylinder control

A method for controlling a telescopic cylinder, wherein the telescopic cylinder comprises:

• a first cylinder, comprising a first piston slidable in a sealed fashion in a jacket which comprises an extension chamber and a re-entry chamber, separated from each other by a head of the first piston;
• a second cylinder, comprising a second piston slidable in a sealed fashion in a jacket, integral with the jacket of the first cylinder, which comprises an extension chamber and a re-entry chamber, separated from each other by a head of the second piston;
• comprising the following steps:
• detecting and quantifying a variation in volume per unit time of the extension chamber of the first cylinder;
• feeding a compensating flow rate of operating fluid to the extension chamber or discharging a compensating flow rate of operating fluid from the extension chamber of the second cylinder;
• adjusting said compensating flow rate as a function of the variation in volume per unit time of the extension chamber of the first cylinder.
