Abstract
An assembly is provided for a piece of rotational equipment. This assembly includes a stationary component, a rotating component, and a dry seal assembly. The dry seal assembly is configured to substantially seal an annular gap between the stationary component and the rotating component. The dry seal assembly includes a seal element and a seal land. The seal element is mounted to the stationary component and is configured to sealingly engage the seal land. The seal land is mounted to the rotating component and is configured to permit gas leakage across the dry seal assembly through a passageway in the seal land.

An assembly for a piece of rotational equipment, comprising:
- a stationary component;
- a rotating component;
- and
- a dry seal assembly configured to substantially seal an annular gap between the stationary component and the rotating component, the dry seal assembly comprising a seal element and a seal land;
- the seal element mounted to the stationary component and configured to sealingly engage the seal land;
- and
- the seal land mounted to the rotating component and configured to permit gas leakage across the dry seal assembly through a passageway in the seal land.
An assembly for a piece of rotational equipment, comprising:
- a seal land comprising a seal land surface and a passageway, the seal land surface arranged at a side of the seal land and extending circumferentially around an axis, and the passageway extending through the seal land from an inlet at the side of the seal land;
- and
- a seal element comprising a seal element surface, and the seal element configured such that an entirety of the seal element surface sealing engages a portion of the seal land surface to form a seal interface between the seal element and the seal land;
- wherein the seal land is rotatable about the axis relative to the seal element;
- and
- wherein the portion of the seal land surface is circumferentially uninterrupted.

- and
- a seal element comprising a seal element surface, and the seal element configured such that the seal element surface sealing engages a portion of the seal land surface to form a seal interface between the seal element and the seal land;
- wherein the seal land is rotatable about the axis relative to the seal element;
- wherein the portion of the seal land surface is circumferentially uninterrupted;
- and
- wherein a radial height of the seal element surface is equal to a radial height of the portion of the seal land surface.
