1. A seal assembly for an aeronautical turbine engine, the seal assembly, comprising:
a passive flow regulator, the passive flow regulator comprising:
a seal body comprising a seal slider and a stator shoe defining a stator face, the seal body defining an aspiration conduit extending through the seal body from the seal slider through the stator face, and
a flow constrictor comprising one or more flexure elements and a constrictor element, the flow constrictor disposed within the aspiration conduit between the seal slider and the stator face, wherein both the flexure elements and the constrictor element move as a result of changes in a pressure differential across the passive flow regulator.
