Beschreibung
Zusammenfassung:	The servomotor comprises a master cylinder driven by a control part (20), a pneumatic servomotor (14) enclosure (16) comprising rear (CA) and front (CB) chambers separated by a piston (22). There are first (VE1) and second (VE2) balancing valve elements for putting the two chambers into communication. There are first (VA1), second (VA2) and third (VA3) inlet valve elements putting the rear chamber in communication with a pneumatic pressure source, and a tubular support (44). The balancing valve elements are carried by a balancing part (44B) of the support and the piston. The inlet valve elements are carried by the first part (20A) of the control part, an inlet end (44A) of the support and the second part (20B) of the control part. The two parts of the control part are connected by means for adjusting their relative axial position according to the power of the force applied by the control part.
