SEAL STRIP FOR SEAL ASSEMBLY AND METHOD TO FORM SAME
Embodiments of the disclosure provide a seal strip for a seal assembly for a turbomachine. The seal strip includes a retaining portion for fixed coupling within a recess in a stationary component of the turbomachine. A plurality of leaf members extend from the retaining portion, and a slit extends between adjacent leaf members of the plurality of leaf members. Each leaf member includes a first stepped edge and an opposing, second stepped edge, and the first stepped edge and the second stepped edge of adjacent leaf members are configured to sealingly mesh in a mounted state of the seal strip in the turbomachine.
ROTATING LEAF SPRING SEAL
A rotating leaf spring seal is disclosed. In various embodiments, the rotating leaf spring seal includes a first annular ring configured for positioning against a support structure; a hook section having an outer surface configured for sealing engagement with a tie shaft and an inner surface configured for receiving a hold down ring; and a spring section disposed between the first annular ring and the hook section.

Seal structure and manufacturing method thereof
An annular seal member 2 is formed by overlapping, in the axial direction D1, a plurality of ring-shape parts 3 which are closed or unclosed when viewed in a radial direction D2 orthogonal to the axial direction D1 of the annular seal member 2. A seal groove 5 has a groove bottom 51 with an outer diameter R51 that increases along the axial direction D1. The inner periphery 22 of the annular seal member 2 contacts the groove bottom 51, and the inner diameter R22 of the inner periphery 22 increases as the outer diameter R51 of the groove bottom 51 increases. By this means, the outer diameter R21 of the outer periphery 21 increases, and the side of the outer periphery 21 of the annular seal member 2 that has a smaller outer diameter R21 does not contact the inner peripheral wall 61 of an inner peripheral wall member 6, and the side of the outer periphery 21 of the annular seal member 2 that has a greater outer diameter R21 does contact the inner peripheral wall 61 of the inner peripheral wall member 6.

Rotary machine with seal device
A rotary machine includes a seal device capable of restricting a flow of a fluid in a clearance between a stationary member and a rotational member. The seal device includes a pressure loss element mounted to the stationary member, a first non-contact type seal protruding from the rotational member toward the pressure loss element and facing the pressure loss element via a first gap, and a second non-contact type seal protruding from the stationary member toward the rotational member, facing the rotational member via a second gap, and being positioned on one side of the pressure loss element in a flow direction of the fluid. The seal device also includes a contact type seal protruding from the stationary member toward the rotational member and being disposed downstream of the pressure loss element and the second non-contact type seal in the flow direction of the fluid.
