A position servo control apparatus for controlling a fluid-operated linear cylinder is disclosed. The helical grooves of the distribution spindle are in permanent flow communication with the acting chamber(s) of the linear cylinder. The orifices of the supply sleeve are in permanent flow communication with the fluid source. The helical grooves cooperate with the orifices to make the piston to translate as a response proportionally to the angular displacement of the distribution spindle. |
