The support assembly may include a support member that may be slidably disposed in a recess formed in the internal assembly and configured to engage an inner surface of the casing. A biasing member may be disposed in a pocket extending radially inward from the recess. The biasing member may at least partially extend into the recess and may be configured to apply a biasing force to the support member disposed therein. ## Claims ### Claim 1 A turbomachine, comprising: a casing having an inner surface; an internal assembly disposed within the casing and comprising a plurality of recesses formed in an outer surface of the internal assembly, each recess comprising a plurality of pockets extending radially inward from the respective recess; and a plurality of support assemblies, each support assembly disposed at least partially within a respective recess of the plurality of recesses and comprising: a support member slidably disposed in the respective recess and configured to engage the inner surface of the casing, and a plurality of biasing members, each biasing member disposed within a respective pocket of the plurality of pockets of the respective recess and at least partially extending into the respective recess, and configured to apply a biasing force to the support member, wherein each support member comprises a contact member and a backing member, the contact member being configured to engage the inner surface of the casing and the backing member being configured to be engaged by a respective plurality of biasing members, and further wherein the contact member of each support member has a protuberance configured to mate with a groove formed in a respective backing member. ### Claim 2 (depends on 1) The turbomachine of claim 1, wherein each support member comprises an insulating material configured to electrically isolate the internal assembly from the casing. ### Claim 3 (depends on 1) The turbomachine of claim 1, wherein an outer surface of the contact member has a radius of curvature equal to a radius of curvature of the inner surface of the casing. ### Claim 4 (depends on 1) The turbomachine of claim 1, wherein each contact member comprises an elastomeric material. ### Claim 5 (depends on 1) The turbomachine of claim 1, wherein each support assembly further comprises a mechanical fastener, the mechanical fastener extending through at least a portion of the respective support member and being coupled with the internal assembly, the mechanical fastener configured to retain the respective support member within the respective recess while allowing the respective support member to be slidably disposed in the respective recess. ### Claim 6 A turbomachine, comprising: a casing having an inner surface; an internal assembly disposed within the casing and comprising a plurality of recesses formed in an outer surface of the internal assembly, each recess comprising a plurality of pockets extending radially inward from the respective recess; and a plurality of support assemblies, each support assembly disposed at least partially within a respective recess of the plurality of recesses and comprising: a support member slidably disposed in the respective recess and configured to engage the inner surface of the casing, and a plurality of biasing members, each biasing member disposed within a respective pocket of the plurality of pockets of the respective recess and at least partially extending into the respective recess, and configured to apply a biasing force to the support member, wherein each support member comprises a contact member and a backing member, the contact member being configured to engage the inner surface of the casing and the backing member being configured to be engaged by a respective plurality of biasing members, wherein each support assembly further comprises a mechanical fastener, the mechanical fastener extending through at least a protion of the support member and coupled wuth the internal assembly, the mechanical fastener configured to retain the support member at least partially within the recess while allowing the support member to be slidably disposed in the recess wherein the mechanical fastener comprises: a threaded portion configured to couple the mechanical fastener with the internal assembly; a shoulder portion extending the respective backing member, the respective backing member configured to slide along the shoulder portion; and a head portion configured to engage the backing member by direct contact therewith, thereby retaining the support member at least partially within the recess.
