Abstract
A brush seal is created between two members, one of which may rotate with respect to the other. A bonding agent is applied to one or both members, each of which may include a groove for application of the bonding agent. Flexible filaments are then embedded into the bonding agent by, for example, electrostatic flocking. After the bonding agent hardens or cures, the brush seal is created.
Claims70
A method of creating a brush seal, comprising:
- applying a bonding agent to at least one member;
- and
- embedding a plurality of flexible filaments into the bonding agent to create the brush seal.
A brush seal, comprising:
- at least one member;
- a bonding agent on a surface of the at least one member;
- a plurality of flexible filaments embedded in the bonding agent;
- and
- wherein there is an absence of sealing rings coupling the plurality of flexible filaments to the at least one member.
A system for creating a brush seal, comprising:
- a bonding agent for applying to at least one member;
- a plurality of flexible filaments;
- and
- a machine for embedding the plurality of flexible filaments into the bonding agent to create the brush seal.
A brush seal flexible filament having a cross-sectional shape with a flow resistance coefficient higher than that of a circular cross-sectional shape.
A brush seal flexible filament having a non-circular cross-sectional shape.
A brush seal flexible filament having a cross-sectional shape with at least one of a corner, an included angle, a flat surface and a concave surface.
A brush seal flexible filament having a cross-sectional shape allowing more eddy currents to form therearound as compared to a circular cross-sectional shape.
