Abstract
An assembly is provided for rotational equipment. This assembly includes a plurality of seal shoes, a seal base and a spring system. The seal shoes are arranged about a centerline in an annular array. The seal shoes include a first seal shoe. The seal base circumscribes the seal shoes. The spring system connects the seal shoes to the seal base. The spring system includes a first spring element and a second spring element. The first spring element extends axially along the centerline in a first axial direction from the seal base to the first seal shoe. The second spring element extends axially along the centerline in a second axial direction from the seal base to the first seal shoe. The second axial direction is opposite the first axial direction.
