    Abstract: A turbine engine including a power gear box shaft, a turbine shaft, a connecting part of annular shape by which one end of the power gear box shaft and one end of the turbine shaft are connected in a rotationally fixed manner, a structural housing, and a guide bearing for guiding the connecting part relative to the housing, is provided. The guide bearing is mounted between the connecting part and the housing and includes an external ring mounted on the housing, an internal ring mounted on the connecting part, and at least one rolling element configured to enable the external ring to roll around the internal ring. The guide bearing is configured to form a ball joint link enabling a relative angular displacement of its external ring with respect to its internal ring.

    Abstract: A hydraulic ram comprising a fixed support, a cylinder that is movable in translation relative to the support, a piston secured inside the cylinder delimiting two chambers with the cylinder and a device for supplying the chambers with hydraulic fluid upstream from the fixed support. The ram is characterised by the fact that the supply device comprises telescopic channels, each telescopic channel comprising two tubular elements sliding one into the other, a first tubular element being rigidly connected to the fixed support at one end and the second tubular element being rigidly connected to the cylinder at at least two points separated from each other along a generatrix of the cylinder. The invention is applicable to controlling the pitch of the blades of a turbine engine propeller.
