Beschreibung
Zusammenfassung:	A supply system for supplying a turbomachine with fluid. The supply system includes at least one centrifugal pump and a fluid recirculation branch. The fluid recirculation branch includes an inlet situated downstream of the centrifugal pump and an outlet situated upstream of the centrifugal pump or fluidically connected with a node situated upstream of the centrifugal pump, in such a way that at least one portion of the fluid circulates in the centrifugal pump. The fluid recirculation branch includes a valve situated between the inlet and the outlet, the valve including a shutter configured to open/close as a function of the temperature of the fluid.
