Title: HOUSING ARRANGEMENT FOR A TURBOMACHINE, AND METHOD FOR ASSEMBLING A HOUSING ARRANGEMENT OF THIS TYPE
Abstract:
The invention relates to a housing arrangement (10) for a turbomachine, comprising an inner housing (12), an outer housing (14) which encloses the inner housing (12) at least partially, and a sealing ring (16) for radial sealing between the inner housing (12) and the outer housing (14). In order to make an assembly of the housing arrangement (10) possible here in a simple and reliable way and without the risk of damage of the sealing ring (16), it is provided according to the invention that a radially outer section of the sealing ring (16) is arranged in an inner circumferential groove (20) of the outer housing (14), and a radially inner section of the sealing ring (16) bears against an outer circumferential face (22) of the inner housing (12), that the sealing ring (16) is interrupted at one point, and that the outer housing (14) has a radial through opening (28) adjacently with respect to the interruption point of the sealing ring (16). The invention relates, furthermore, to a method for assembling a housing arrangement (10) of this type.
