<p>An example method of using a servomechanism can include controlling a reversible positive displacement pump that is located in a first chamber of a housing to push a fluid, via a first passage in the housing, against one side of a vane that is rotably disposed in a second chamber of a housing to rotate an output shaft that is coupled to the vane and controlling the reversible positive displacement pump to push a fluid, via a second passage in the housing, against another side of a vane to revers rotation of the output shaft.</p> |
