Abstract:
1. An actuating cylinder comprising: a longitudinal cylinder body; a longitudinal cylinder rod traversing a front transverse wall of the cylinder body, the cylinder body comprising a rear transverse wall situated at a distance from a rear end of the cylinder rod inside the body; a longitudinal sleeve coupled to the cylinder body and located therein; a driving means of operating longitudinally the cylinder rod relative to the cylinder body located radially between the sleeve and the cylinder rod; a sensor supported by a front end portion of the cylinder rod; a longitudinally deformable tubular linking means, comprising at least two tubular longitudinal portions mounted in telescopic relation to one another, to delimit a longitudinal channel of variable length, the linking means having at least one portion coupled to the front end portion of the cylinder rod and at least one other portion coupled to the rear transverse wall of the cylinder body and the channel emerging at the rear of this rear transverse wall; at least one electric connecting wire which is coupled to the sensor and which extends in the longitudinal channel of variable length backwards so as to emerge at the rear of the rear transverse wall; and an electric motor whose rotor is supported by the sleeve and whose stator is supported by the cylinder body.
