Abstract
An electric power actuator and a method of controlling such an actuator are disclosed. The actuator (1) can include means (17, 26) for limiting the pressure difference in both chambers (9, 10) of a hydraulic jack (8) of the actuator (1) to a limit pressure which is lower than an opening pressure of a pressure relief valve (11) of the actuator (1).
