Accumulator integrated into a fuel line

A fuel pressure accumulator for a fuel supply circuit of a turbine engine having a pipe in which a main flow of fuel flows from upstream to downstream, the fuel pressure accumulator comprising:

• a housing configured to be positioned adjacent to the pipe and receive a deformable enclosure configured to confine, in a sealed manner, a gas subjected to a pressure equal to a nominal fuel pressure present in the pipe, the deformable enclosure comprising a movable wall configured to be arranged in contact with the fuel and to deform under the effect of a fuel overpressure such that the gas confined in the enclosure, by being compressed, dampens the fuel overpressure, wherein the housing is coaxial with the pipe;
• and
• a permeable chamber delimited at least partially by the housing, the permeable chamber pressurizing the deformable enclosure and communicating with the main flow of fuel by a grid having staged walls which are tilted substantially in the direction of the deformable enclosure with respect to a direction of the main flow flowing along the grid.
