A power supply system with prioritized network selection is disclosed. In one aspect, the system can be connected to the output of N power supply networks (R, . . . , R), N being an integer greater than or equal to 2. It includes N controllable energy transfer members (T, . . . , T) each connected to a power supply network (R, . . . , R), control subsystem () for selecting one power supply network (R, . . . , R) by commanding the controllable member (T, . . . , T) connected to the selected power supply network (R, . . . , R) into a closed position, and energy storage subsystem capable of delivering a storage voltage (V). It may also comprise an energy converter connected to the output to the N controllable energy transfer members (T, . . . , T), the control subsystem being able to command the energy converter and the N controllable energy transfer members (T, . . . , T) to select at most one energy source from among the N power supply networks (R, . . . , R), as a function of the N input voltages (V, . . . , V) and the storage voltage (V).

Power supply system with prioritized network selection

A rotation-guiding device includes a fixed support and a movable support able to rotate around the fixed support about an axis of rotation, wherein an interface between the fixed and movable supports includes a bearing to guide the movable support in rotation about the fixed support, a flexible dynamic seal providing seal-tightness between the fixed support and the movable support that is mounted between a friction track secured to one of said supports and a mechanical structure secured to the other support, and which includes a metal spring to provide the contact force for the seal between the friction track and the mechanical structure. The dynamic seal may be mounted parallel to the axis of rotation so that the contact force is exerted parallel to the axis of rotation.
