摘要： An annular stator seal support extends radially between a radial inner support side and a radial outer support side. A secondary seal includes a first radially extending secondary seal sidewall surface, a second radially extending secondary seal sidewall surface and a third radially extending secondary seal sidewall surface. An annular stator sleeve support includes a channel radially distal the radial inner support side, the channel includes a first radially extending channel sidewall and a second radially extending channel sidewall located axially forward of the first radially extending channel sidewall, and a third radially extending channel sidewall located axially behind the first radially extending channel sidewall. The first radially extending seal sidewall surface contacts the first radially extending channel sidewall, and the second radially extending channel sidewall is axially spaced from the second radially extending secondary seal sidewall surface.

摘要： An assembly includes a housing, a carrier, a spring element and a seal element. The housing includes a bore and an annular groove that extends axially along a centerline into the housing from the bore. The carrier projects axially along the centerline into the annular groove. The carrier is configured to translate axially along the centerline relative to the housing. The spring element is arranged within the annular groove. The spring element is configured to bias the carrier axially away from the housing along the centerline. The seal element is mounted to the carrier and arranged within the bore.

摘要： A seal assembly is provided that extends along an axial centerline. The seal assembly includes a seal support, a seal housing, a plurality of torque pins and a plurality of stopper collars. The seal housing includes a plurality of slots arranged circumferentially around the centerline. The slots extend axially through the seal housing, and one or more of the slots has a lateral slot width. The torque pins are connected to the seal support. Each of the torque pins respectively extends axially through a uniquely associated one of the slots to a distal pin end. Each of the stopper collars is uniquely associated with and connected to a respective one of the torque pins at the pin end. One or more of the stopper collars has a lateral collar width that is less than the slot width.
