<p>The servo-motor consists of a sealed housing with a wall (100), and a control rod (2) sliding in an aperture (101) in the wall and capable of being pushed inside the housing to provide a progressive link between the interior (102) of the housing and an auxiliary pressure source which exercises a counter-pressure on the rod. The servo-motor has a cylindrical sleeve (7) between the aperture in the wall and the control rod, sealed relative to the wall and the rod and able to slide in relation to them, with a stop (8) preventing the sleeve from sliding towards the outside of the housing. Differential reaction components (9,10,70) transmit at least part of the force acting on the sleeve from the pressure inside the housing to the control rod, and comprise a nut (9), a spring (10) and a stop formed by the end of the sleeve.</p> |
