Abstract
A turbomachine includes a rotor shaft having an outer surface, a seal carrier forming an annulus about the rotor shaft, and a seal member. The seal carrier at least partially defines a pressure chamber. The turbomachine further includes a seal member support system including a flex body having a contact portion in contact with the seal carrier, and a flex portion extending from the contact portion towards the outer surface of the rotor shaft. The flex portion is coupled to the seal member and is configured to hold the seal member at a radial distance away from the outer surface of the rotor shaft when a pressure inside the pressure chamber is equal to or below a minimum pressure threshold value, and to flex and move the seal member towards the outer surface of the rotor when the pressure inside the pressure chamber exceeds the minimum pressure threshold value.
