Abstract

A seal assembly comprising a first movable stator member movable between a sealing position and a non-sealing position, a second fixed stator member, the first stator member being movable relative to the second stator member, the seal assembly further comprising at least one flexure member coupled to the second stator member, and at least one biasing member coupled between the at least one flexure and the movable stator for biasing the movable stator to a non-sealing position.

Claims

exact text as granted — not AI-modified
1 . A seal assembly comprising:
 a first movable stator member movable between a sealing position and a non-sealing position, a second fixed stator member, the first stator member being movable relative to the second stator member, the seal assembly further comprising at least one flexure member coupled to the second stator member, and at least one biasing member coupled between the at least one flexure member and the movable stator for biasing the movable stator to a non-sealing position.   
   
   
       2 . The seal assembly of  claim 1  having at least two flexure members and two biasing members, each biasing member coupled to a flexure member. 
   
   
       3 . The seal assembly as claimed in  claim 1 , the second stator comprising a base and a surface along the base, the first stator comprising a sealing member that sealingly engages the contact surface of said base. 
   
   
       4 . The seal assembly of  claim 3  wherein the first stator comprises a yoke, said member being located in said yoke.
