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.
