ABSTRACT:
A flexible bellows connecting device which positions an output member has a pair of jacks (1,2) equipped with deformation sensors (12,13). A pair of variable capacity bellows pump reservoirs (3,4) permit predetermined motion of the jacks. An electric motor (19) drives the pump. The sensor signals provide deformation difference signal feedback to the electronic control system which may include a microprocessor (5) for closed loop position control.
