Abstract
A brush seal assembly for sealing a gap between a first component and a second component, comprising: a body; bristles extending from the body; and an extension from the body, the extension having an elongated slot therein. The slot, when the brush seal assembly mounts between the first and second components, allows the brush seal assembly to float within the gap. An axial brush seal assembly, comprising: a body; bristles extending from the body; and means for allowing movement of the brush seal assembly in an axial direction within the gap. An apparatus, comprising: a first component; a second component spaced from the first component in an axial direction; and an axial brush seal assembly movably mounted between the first and second components. The brush seal assembly can move in said axial direction.

A brush seal assembly for sealing a gap between a first component and a second component, comprising:
- a body;
- bristles secured to and extending from said body in a direction;
- and
- an extension from said body, said extension having a slot therein with a depth, said slot being elongated transverse to said depth;
- wherein said slot, when said brush seal assembly mounts between said first and second component, allows said brush seal assembly to float within said gap along said direction.
An axial brush seal assembly for sealing a gap between a first component and a second component having an elongated slot and keyways in communication therewith, comprising:
- a body positionable in said elongated slot so that said brush seal assembly can move in an axial direction within said gap;
- bristles extending from said body and engaging said first and second components;
- and
- splines extending from said body and positionable within said keyways to prevent rotation of said brush seal assembly.
An axial brush seal assembly for sealing a gap between a first component and a second component, comprising:
- a body;
- bristles secured to and extending from said body, wherein said bristles engage said first and second components;
- and
- an extension from said body, said extension having a first section extending radially from said body, a second section extending axially from said first section, and a slot in said second section that is elongated in said axial direction for allowing movement of said brush seal assembly in an axial direction within said gap.
An apparatus, comprising:
- a first component;
- a second component spaced from said first component in an axial direction;
- an axial brush seal assembly movably mounted between said first and second components and having bristles engaging said first and second components;
- and
- a spring;
- wherein said brush seal assembly can move in said axial direction and said spring biases said brush seal assembly.
A method of sealing a gap between a first component and a second component, comprising the steps of:
- placing an axial brush seal assembly between said first and second components, said axial brush seal assembly having bristles that engage said first and second components;
- allowing said brush seal assembly to float in said gap;
- and
- preventing rotation of said brush seal assembly.
An axial brush seal assembly for sealing a gap between a first component and a second component having an elongated slot therein that is closed at its ends, comprising:
- a body;
- bristles extending from said body;
- and
- a fastener rigidly mounted to said body and adapted to move during installation to avoid one of said closed ends of said elongated slot and to extend into said elongated slot after installation;
- wherein said fastener can travel within said elongated slot to allow movement of said brush seal assembly within said gap.
A method of sealing a gap between a first component and a second component, comprising the steps of:
- placing an axial brush seal assembly between said first and second components, said axial brush seal assembly having a body, bristles extending from said body, and an extension from said body, said extension having a slot therein with a depth, said slot being elongated transverse to said depth;
- allowing said brush seat assembly to float in said gap;
- and
- applying a bias force to said brush seal assembly.
