摘要： The invention relates to a depression servomotor comprising a rigid envelope (1) the inside of which is partitioned in at least a first and a second chamber (2, 3) by means of at least one partition wall (4), and a tubular bellow (5) traversing the first chamber (2), presenting an extremity (51) integral with the partition wall and providing for a tight communication between the second chamber (3) and the outside of the envelope (1). The bellow is made integral with the partition wall by means of a spring holding part (6) which is set in place through the inside of the bellow.
