Abstract
The invention concerns a fuel system (1) for a turbomachine comprising: —a control circuit (9a), —a main circuit (9b), —a flow rate regulator (2), suitable for regulating the flow of fuel in the control circuit (9a) and in the main circuit (9b) depending on the speed of the turbomachine, and —a drain tank (4) being designed to draw fuel from, store fuel in and drain fuel into the main circuit (9b) on the basis of the pressure difference between the main circuit (9b) and the tank (5) or the high-pressure pump (6) to which it is connected.
