Brush seal placement between rotating and stationary components with reversely bent leaf spring

A brush seal and spring combination for disposition between a first rotatable component and a second component fixed against rotation, comprising:

• an arcuate brush seal segment for disposition between the first component and the second component and including a pair of arcuate plates and a plurality of brush bristles projecting therefrom having free ends for sealing with the first rotatable component;
• and
• an elongated leaf spring for disposition between the brush seal segment and the second component;
• said leaf spring being secured adjacent one end to the brush seal segment and having first and second circumferentially extending reversely curved portions, said first curved portion projecting away from said brush seal segment for engaging the second component at a location along said spring intermediate opposite ends thereof, said second curved portion being located adjacent a second end of said spring opposite said one end and in engagement with the brush seal segment;
• said leaf spring being welded to said brush seal segment at said one end thereof.

A brush seal assembly, comprising:

• a first rotatable component having an axis of rotation;
• a second component fixed against rotation about said axis and radially outwardly of said rotatable component, said fixed component having a radially inwardly opening groove and an axially opening slot in communication with said groove;
• an arcuate brush seal between said rotatable component and said fixed component in said groove and including an axially projecting hook for reception in said slot, said brush seal having a support mounting a plurality of bristles projecting therefrom and having free ends in sealing relation with said rotary component;
• said support having an arcuate radial outer surface;
• a leaf spring between said fixed component and said outer face for biasing said brush seal for movement in a generally radially inward direction, said leaf spring being fixedly secured adjacent one end to the brush seal adjacent one end of the segment and having first and second circumferentially extending reversely curved portions, said first curved portion projecting away from said brush seal for engaging the second component at a location along said spring intormodiato substantially medially of opposite ends thereof, said second curved portion being located adjacent a second end of said spring opposite said one end and in engagement with the brush seal outer face.

• a first rotatable component having an axis of rotation;
• a second component fixed against rotation about said axis and radially outwardly of said rotatable component, said fixed component having a radially inwardly opening groove and an axially opening slot in communication with said groove;
• an arcuate brush seal between said rotatable component and said fixed component in said groove and including an axially projecting hook for reception in said slot, said brush seal having a support mounting a plurality of bristles projecting therefrom and having free ends in sealing relation with said rotary component;
• said support having an arcuate radial outer surface;
• a leaf spring between said fixed component and said outer face for biasing said brush seal for movement in a generally radially inward direction, said leaf spring being secured adjacent one end to the brush seal adjacent one end of the segment and having first and second circumferentially extending reversely curved portions, said first curved portion projecting away from said brush seal for engaging the second component at a location alone said spring intermediate opposite ends thereof, said second curved portion being located adjacent a second end of said spring opposite said one end and in engagement with the brush seal outer face;
• said support including a pair of plates, said bristles being secured to and between said plates by a circumferentially extending weld.

• said support having an arcuate radial outer surface;
• a leaf spring between said fixed component and said outer face for biasing said brush seal for movement in a generally radially inward direction, said leaf spring being secured adjacent one end to the brush seal adjacent one end of the segment and having first and second circumferentially extending reversely curved portions, said first curved portion protecting away from said brush seal for engaging the second component at a location along said spring intermediate opposite ends thereof, said second curved portion being located adjacent a second end of said spring opposite said one end and in engagement with the brush seal outer face;
• said leaf spring being welded to said brush seal at said one end thereof.
