Tank having an inclined partition provided at its ends with through-holes for continuous supply of a supply liquid to a turbine engine
View Patent ↗The tank for a turbine engine comprises a partition separating a first compartment from a second compartment of the tank , the partition having a first end and a second end, the second end being closer to the bottom of the tank than the first end, the partition being inclined from the first end to the second end in the first direction and in the direction of the first outlet to the second outlet , the partition comprising at least one first Through-hole near the first end and at least one second through-hole closer to the second end than the first hole.
1. Supply liquid tank for a turbine engine, comprising a first compartment and a second compartment wherein the bottom of the tank is located,
the first compartment having an inlet for supply liquid, a first outlet and a second outlet located according to a first direction with respect to the first outlet so that the second outlet is closer to the bottom of the tank than the first outlet,
wherein the tank comprises a partition separating the first compartment and the second compartment,
wherein the partition has a first end and a second end opposite to the first end, the second end being closer to the bottom of the tank than the first end,
wherein the partition is inclined from the first end to the second end in the first direction in the direction of the first outlet to the second outlet,
wherein the partition comprises at least one first through-hole near the first end and at least one second through-hole closer to the second end than the first hole.
2. Tank according to claim 1 , wherein the supply liquid is lubricant.
3. Tank according to claim 1 , wherein the first direction is the height of the tank.
4. Tank according to claim 1 , wherein the second hole is located near the second end.
5. Tank according to claim 1 , wherein the partition is inclined so as to form an angle of 5° to 85° with the bottom of the tank.
6. Tank according to claim 5 , wherein the partition is inclined so as to form an angle of 30° to 60° with the bottom of the tank.
7. Tank according to claim 6 , wherein the partition is inclined so as to form an angle of 40° to 50° with the bottom of the tank.
8. Tank according to claim 1 , wherein the partition comprises a first surface for the passage of supply liquid comprising the first hole and a second surface for the passage of supply liquid comprising the second hole,
wherein the first passage surface is separated from the second passage surface, and wherein each passage surface has a surface area substantially equal to one-tenth the total surface of the partition.
9. Tank according to claim 1 , wherein the first outlet is closer to the first end than the second end, and wherein the second outlet is closer to the second end than the first end.
10. Tank according to claim 1 , wherein the first outlet is an outlet configured to tolerate an interruption in the supply of supply liquid and wherein the second outlet is an outlet requiring a continuous supply of supply liquid.
11. Tank according to claim 10 , wherein the first outlet is as an outlet for supplying lubricant to at least one turbine engine bearing.
12. Tank according to claim 10 , wherein the second outlet is a pump for supplying lubricant for changing a propeller pitch.
13. Turbine engine lubricating system for supplying lubricant to at least one turbine engine bearing and for supplying lubricant to a turbine engine propeller pitch changing mechanism, comprising the tank according to claim 1 .
