Abstract: A device for controlling feed of fluid to equipment, such as a heat exchanger, the device including: a fluid slide valve mounted in a fluid circuit including a slide movable between two positions, a first position in which it allows the fluid to flow through the equipment, and a second position in which it prevents the fluid from flowing through the equipment; a laminar flow constriction arranged in the fluid circuit upstream from the slide valve; and a drive mechanism moving the slide of the slide valve between its two positions by head loss of the fluid in the laminar flow constriction.

Abstract: A device includes a first hot fuel bleed, a second cold fuel bleed, a fuel pressure regulator including a fuel inlet line, a fuel outlet line and a fuel pressure set point line, the pressure of the outlet line being set by the regulator to a fixed divergence from the pressure of the set point line, a first connector to connect the first bleed to the inlet line of the regulator and the second bleed to the set point line of the regulator, when a first pressure of the first bleed is greater than or equal to a second pressure of the second bleed and to connect the first bleed to the set point line of the regulator and the second bleed to the inlet line of the regulator when the first pressure is lower than the second pressure, and a second connector.

Abstract: A fuel circuit for a turbine engine, the fuel circuit comprising: a fuel return valve connected to the main circuit and to a fuel tank, the valve being capable of adopting an open position in which the valve allows an excess quantity of fuel to be returned to the tank, and a closed configuration in which the return of fuel to the tank is blocked; a first hydraulic line connecting the valve to the main circuit, and including a first filter; a second hydraulic line connecting the valve to the main circuit, and including a second filter; and an intermediate hydraulic line connected to the first and second lines downstream from the filters, the first and second lines being hydraulically connected together by the intermediate line when the valve is in the closed configuration.
