Lubrication system having segmented anti-backflow feature
A tank includes a tank discharge passageway at least partially within a tank body. A segmented anti-back flow structure is mounted adjacent to the tank body and the tank discharge passageway.
1. A lubricant tank, comprising:
a lubricant tank body;
a lubricant tank discharge passageway at least partially within said lubricant tank body; and
a segmented anti-back flow structure mounted adjacent to and disposed in said lubricant tank body and adjacent to and in fluid communication with said lubricant tank discharge passageway, wherein said segmented anti-back flow structure includes a multiple of walls each of which includes an outwardly projecting tube which extends therethrough.
2. The lubricant tank as recited in claim 1 , wherein each of said tubes extends towards an adjacent lower wall.
3. The lubricant tank as recited in claim 1 , wherein each of said tubes extends towards a lower wall of said multiple of walls.
4. A lubricant tank, comprising:
a lubricant tank body;
a lubricant tank discharge passageway at least partially within said lubricant tank body; and
a segmented anti-back flow structure mounted adjacent to and disposed in said lubricant tank body and adjacent to and in fluid communication with said lubricant tank discharge passageway, wherein said segmented anti-back flow structure includes a multiple of walls each of which includes a tube which extends therethrough, and wherein at least one of said tubes extends toward a bottom of said lubricant tank body.
5. The lubricant tank as recited in claim 4 , wherein each of said multiple of walls surround said lubricant tank discharge passageway.
6. A lubricant tank, comprising:
a lubricant tank body;
a lubricant tank discharge passageway at least partially within said lubricant tank body; and
a segmented anti-back flow structure mounted adjacent to and disposed in said lubricant tank body and adjacent to and in fluid communication with said lubricant tank discharge passageway, wherein said segmented anti-back flow structure includes a multiple of walls each of which includes a tube which extends therethrough, and wherein each of said multiple of walls surround said lubricant tank discharge passageway.
7. A lubrication system, comprising:
a main lubricant tank configured to hold lubricant that is communicated from said main lubricant tank to a component along a first communication path;
an auxiliary lubricant tank configured to hold lubricant that is communicated from said component to said auxiliary lubricant tank along a second communication path, said first communication path separate from said second communication path;
an auxiliary lubricant tank discharge passageway at least partially within said auxiliary lubricant tank, said auxiliary lubricant tank discharge passageway, includes an opening to permit lubricant transfer between said auxiliary lubricant tank and said auxiliary lubricant tank discharge passageway; and
a segmented anti-back flow structure mounted in said auxiliary lubricant tank and adjacent to said auxiliary lubricant tank discharge passageway, and wherein said auxiliary lubricant tank and said auxiliary lubricant tank discharge passageway are defined along a non-linear axis, and wherein said segmented anti-back flow structure includes a multiple of walls at least one of which includes an outwardly projecting tube which extends therethrough.
8. The lubrication system as recited in claim 7 , wherein at least one of said tubes extends toward a bottom of said auxiliary lubricant tank.
9. The auxiliary lubricant tank as recited in claim 7 , wherein at least one of said tubes extends towards an adjacent lower wall with respect to a bottom of said auxiliary lubricant tank.
10. A method of reducing lubrication starvation from a lubrication system in communication with a geared architecture for a gas turbine engine comprising:
segmenting an auxiliary lubricant tank defined around an auxiliary lubricant tank discharge passageway.
11. The method as recited in claim 10 , further comprising:
segmenting the auxiliary lubricant tank with a multiple of walls at least one of which includes a tube which extends therefrom.
12. The method as recited in claim 11 , further comprising:
locating the multiple of walls with respect to a bottom of the auxiliary lubricant tank, each of the tubes directed toward the bottom from a respective wall.
13. The method as recited in claim 10 , further comprising:
orienting the auxiliary lubricant tank and the auxiliary lubricant tank discharge passageway along a non-linear axis.
14. The method as recited in claim 13 , further comprising:
forming an opening in the auxiliary lubricant tank discharge passageway along an inner radius thereof.
