Abstract
Abstract A connecting device for use in a gas turbine engine is provided wherein first and second fluid carrying members disposed in a plenum are maintained engaged in a substantially fluid-tight joint. Means are provided for establishing a leakage path from the joint to a location exterior to the plenum with the pressure at the exterior location being lower than the pressure of air in the plenum.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
98 words
For use in a gas turbine engine having a plenum of pressurized fluid flowing therein the invention comprising: first and second fluid carrying members disposed in said plenum and adapted to carry a second fluid; clamping means for maintaining said members engaged at a substantially fluid-tight joint, said joint disposed in said plenum; means disposed between said plenum and said joint for establishing a fluid leakage path for said second fluid, said path extending from said joint to a location exterior to said plenum, said exterior location disposed at a pressure lower than the pressure in said plenum.
Claim 2
Dependent Claim
98 words
For use in a gas turbine engine having a plenum of pressurized fluid flowing therein the invention comprising: first and second fluid carrying members disposed in said plenum and adapted to carry a second fluid; clamping means for maintaining said members engaged at a substantially fluid-tight joint, said joint disposed in said plenum; means disposed between said plenum and said joint for establishing a fluid leakage path for said second fluid, said path extending from said joint to a location exterior to said plenum, said exterior location disposed at a pressure lower than the pressure in said plenum.
Claim 3
Dependent Claim
45 words
The invention as set forth in claim 1 further comprising: means for admitting said pressurized plenum fluid from said plenum to said leakage path for establishing a flow of said pressurized plenum fluid in said path away from said joint and toward said exterior location.
Claim 4
Dependent Claim
34 words
The invention set forth in claim 1 wherein said path establishing means comprise an elongated cylindrical hollow member surrounding one of said fluid carrying members and spaced therefrom to define said fluid leakage path.
Claim 5
Dependent Claim
34 words
The invention as set forth in claim 2 wherein said admitting means is comprised of an aperture extending through said hollow member to establish fluid communication between said fluid leakage path and said plenum.
Claim 6
Dependent Claim
107 words
For use in a gas turbine engine, having a plenum of pressurized air therein, a connecting device comprising: first and second fluid conduits having first and second sealing surfaces, respectively in abutting sealing engagement in said plenum to define a substantially fluid-tight joint; a hollow member surrounding at least one of said conduits and spaced therefrom to define a fluid leakage path between said hollow member and said one of said conduits said path extending from said joint to a location exterior to said plenum, said location disposed at a lower pressure than the pressure in said plenum; and clamping means for maintaining engagement between said surfaces.
Claim 7
Dependent Claim
107 words
For use in a gas turbine engine, having a plenum of pressurized air therein, a connecting device comprising: first and second fluid conduits having first and second sealing surfaces, respectively in abutting sealing engagement in said plenum to define a substantially fluid-tight joint; a hollow member surrounding at least one of said conduits and spaced therefrom to define a fluid leakage path between said hollow member and said one of said conduits said path extending from said joint to a location exterior to said plenum, said location disposed at a lower pressure than the pressure in said plenum; and clamping means for maintaining engagement between said surfaces.
Claim 8
Dependent Claim
41 words
The invention as set forth in claim 5 further comprising: means for admitting pressurized air from said plenum to said leakage path for establishing a flow of pressurized air in said path away from said joint and toward said exterior location.
