Abstract
Perfections in a hydraulic actuation device, characterized in that they include at least one hydraulic drive member of the variable volume type, as well as a variable volume receptacle, whose variation is opposite to that of the driving member but of the same value, while the liquid that fills the entire internal volume of the device is transferred from the receptacle to the driving means, or vice versa, by means of a pump unit.
