Archivio Istituzionale della RicercaThe invention relates to a prosthesis (1) for limbs of the human body, in particular the leg, actuated by means of an actuator (10) capable of both generating and collecting energy. The actuator is a linear electro-hydrostatic (EHA) one, and is more compact and efficient than traditional drives based on electro-mechanical gears. Through a suitable kinematic chain, the actuator (10) produces an angle-dependent transmission ratio. The invention also comprises a generated rotor pump (20), whose external rotor is supported by rolling means.

Abstract
The invention relates to a prosthesis (1) for limbs of the human body, in particular the leg, actuated by means of an actuator (10) capable of both generating and collecting energy. The actuator is a linear electro-hydrostatic (EHA) one, and is more compact and efficient than traditional drives based on electro-mechanical gears. Through a suitable kinematic chain, the actuator (10) produces an angle-dependent transmission ratio. The invention also comprises a generated rotor pump (20), whose external rotor is supported by rolling means.
