A flow sleeve for use in a turbine engine including a compressor section, a combustion section, and a turbine section downstream from the combustion section. The flow sleeve includes a sleeve wall defining a pre-mixing passage of the combustion section and has a forward end proximate to a cover plate of the combustion section and an opposed aft end. The sleeve wall includes a first wall section extending axially from the sleeve wall forward end and a second wall section extending from the first wall section between the forward and aft ends of the sleeve wall toward the aft end of the sleeve wall. A cavity is formed between the first wall section and the second wall section.

1. A flow sleeve for use in a turbine engine comprising a compressor section, a combustion section, and a turbine section downstream from the combustion section, the flow sleeve comprising: a sleeve wall defining a pre-mixing passage where fuel is mixed with air before entering a combustion chamber defined by a liner of the combustion section, the pre-mixing passage being defined between the liner and the sleeve wall with the sleeve wall being located radially outwardly from the liner, the sleeve wall having a forward end proximate to a cover plate of the combustion section and an opposed aft end, said sleeve wall comprising;a first wall section extending axially from said sleeve wall forward end; anda second wall section extending from said first wall section between said forward and aft ends of said sleeve wall toward said aft end of said sleeve wall, wherein a cavity is formed between said first wall section and said second wall section; anda cover structure located at least partially forward of said second wall section and affixed to a radially inner surface of said sleeve wall and housing a fuel supply tube in fluid communication with a source of fuel for delivering fuel from said source of fuel to said pre-mixing passage. 2. The flow sleeve according to claim 1, wherein said cavity is formed in said sleeve wall adjacent to said sleeve wall aft end. 3. The flow sleeve according to claim 1, wherein said sleeve wall comprises an annular sleeve wall and said cavity comprises an annular channel defining a fuel flow passageway between said first and second wall sections. 4. The flow sleeve according to claim 3, further comprising a fuel dispensing structure associated with said fuel flow passageway for distributing fuel from said annular channel to said pre-mixing passage. 5. The flow sleeve according to claim 1, wherein said cover structure extends substantially axially along and is affixed to a radially inner surface of said first wall section and terminates at an opening formed in said second wall section. 6. The flow sleeve according to claim 5, wherein said fuel supply tube extends through said cover plate, within said cover structure, and through said opening formed in said second wall section into said cavity. 7. The flow sleeve according to claim 1, further comprising a web member disposed in said cavity extending radially between said first and second wall sections. 8. The flow sleeve according to claim 7, wherein said web member divides said cavity into a first portion and a second portion. 9. The flow sleeve according to claim 8, wherein said second portion of said cavity comprises a fuel flow passageway for delivering fuel to said pre-mixing passage. 10. The flow sleeve according to claim 1, wherein said sleeve wall comprises different inner diameters located at different axial locations along said flow sleeve. 11. The flow sleeve according to claim 10, wherein said forward end of said sleeve wall comprises a first inner diameter and said aft end of said sleeve wall comprises a second inner diameter, said first inner diameter being greater than said inner second diameter. 12. A flow sleeve for use in a turbine engine comprising a compressor section, a combustion section and a turbine section downstream from the combustion section, the flow sleeve comprising: an annular sleeve wall defining a pre-mixing passage where fuel is mixed with air before entering a combustion chamber defined by a liner of the combustion section with the sleeve wall being located radially outwardly from the liner, a fuel dispensing structure distributing fuel into said pre-mixing passage, the sleeve wall having a forward end proximate to a cover plate of the combustion section and an opposed aft end, wherein said fuel dispensing structure extends from said cover plate proximate to said forward end of said sleeve wall, said sleeve wall comprising;a first wall section extending axially from said sleeve wall forward end to said sleeve wall aft end;a second wall section radially inward from said first wall section and comprising a conical shaped portion and a cylindrical shaped portion, said conical shaped portion extending from said first wall section between said forward and aft ends of said sleeve wall, said cylindrical shaped portion extending from said conical shaped portion to said aft end of said sleeve wall, wherein a cavity is formed between said first wall section and said second wall section and wherein the premixing passage is defined radially between said second wall section and the liner. 13. The flow sleeve according to claim 12, wherein said cavity comprises an annular channel defining a fuel flow passageway between said first and second wall sections. 14. The flow sleeve according to claim 13, wherein the fuel dispensing structure is associated with said fuel flow passageway for distributing fuel from said annular channel to said pre-mixing passage. 15. The flow sleeve according to claim 13, further comprising a cover structure affixed to a radially inner surface of said sleeve wall adapted to house a fuel supply tube in fluid communication with a source of fuel for delivering fuel from said source of fuel to said fuel flow passageway. 16. The flow sleeve according to claim 15, wherein said cover structure extends substantially axially along and is affixed to a radially inner surface of said first wall section and terminates at an opening formed in said second wall section. 17. The flow sleeve according to claim 12, further comprising a web member disposed in said cavity and extending radially between said first and second wall sections, wherein said web member divides said cavity into a first portion and a second portion, said second portion comprising a fuel flow passageway for delivering fuel to said pre-mixing passage. 18. The flow sleeve according to claim 12, wherein said sleeve wall comprises different inner diameters located at different axial locations along said flow sleeve. 19. The flow sleeve according to claim 18, wherein said forward end of said sleeve wall comprises a first inner diameter and said aft end of said sleeve wall comprises a second inner diameter, said first inner diameter being greater than said inner second diameter. 20. The flow sleeve according to claim 16, wherein said fuel supply tube extends through said cover plate, within said cover structure, and through said opening formed in said second wall section into said cavity.
