Abstract
A seal assembly for a turbine engine extends along a center axis and includes a seal support and a seal carrier configured to translate relative the seal support. A seal is connected to the seal carrier and a spring is disposed between the seal support and the seal carrier. A spring carrier is disposed between the spring and the seal support. A first end of the spring is connected to the spring carrier and the spring carrier is connected to the seal support. The spring includes a second end disposed opposite the first end of the spring. The second end of the spring contacts the annular seal carrier.

A seal assembly for a turbine engine, the seal assembly extending along a center axis and comprising:
- an annular seal support arranged circumferentially around the center axis;
- an annular seal carrier arranged circumferentially around the center axis;
- an annular seal connected to the seal carrier and arranged circumferentially around the center axis;
- a spring disposed between the annular seal support and the annular seal carrier;
- and
- a spring carrier disposed between the spring and the annular seal support, wherein a first end of the spring is connected to the spring carrier and the spring carrier is connected to the annular seal support.
A gas turbine engine comprising:
- a mid-turbine frame arranged circumferentially around a center axis of the gas turbine engine;
- a bearing support disposed radially inward from the mid-turbine frame and connected to the mid-turbine frame;
- a bearing assembly disposed radially inward of the bearing support;
- and
- a seal assembly, the seal assembly comprising:
- an annular seal support arranged circumferentially around the center axis, wherein the annular seal support is connected to the bearing support;
- an annular seal carrier arranged circumferentially around the center axis and positioned axially between the annular seal support and the bearing assembly;
- an annular seal connected to the seal carrier, wherein the annular seal extends from the annular seal carrier towards the bearing assembly;
- a spring disposed between the annular seal support and the annular seal carrier;
- and
- a spring carrier disposed between the spring and the annular seal support, wherein a first end of the spring is connected to the spring carrier, and the spring carrier is connected to the annular seal support.
