摘要

Sofa convertible into a bed, essentially characterized in that it is constituted by two symmetrical parts of the mattress in an overlapping position, which are articulated by one of their edges so that one rotates in relation to the other in a book-like manner, both parts of the bed base being provided with a respective frame of different height that acts as a double backrest in folded position, while the frame of the rotating part becomes a complementary leg depending on the folding of said part of the bed base to transform the sofa into a bed, with the particularity, that the cushion corresponding to the backrest comprises two articulated parts of which one is disposed in front of the frames of the sofa, while the other is located behind the latter acting as a contact area on the wall.

权利要求

1. A method of adjusting oil flow to a gas turbine engine comprising providing a gearbox driven by at least one engine shaft, an oil system comprising a pump drivingly connected to the gearbox, an oil tank connected to the pump via a supply pipe, a delivery pipe connecting the pump to the engine for delivery of oil thereto, and an anti-siphon pipe connected between the tank and the delivery pipe to provide an excess oil flow to the engine and an oil flow over a sight glass in the tank, the anti-siphon pipe including a variable flow valve for regulating the flow of oil passing therethrough, wherein the variable flow valve is operable via a drive means and the drive means is operated via an engine control system, the method further comprising the steps of: operating the gas turbine engine to drive the gear box and oil system, thereby supplying oil to the engine; and opening the valve to increase oil flow at low engine speeds to provide adequate oil flow over the sight glass to provide fire protection.

2. The method according to claim 1 , wherein the low engine speed comprises sub-idle or windmill speeds.

3. The method according to claim 1 , wherein the engine control system operates the valve in response to shaft speed or oil pressure.

4. The method according to claim 1 , wherein a sufficient amount of oil is provided to the sight glass at low engine speeds to prevent failure of the sight glass through fire.

5. The method according to claim 1 , wherein the anti-siphon pipe provides a flow of oil over the sight glass.

6. A method according to claim 1 , wherein the oil system further comprises a second pipe connecting the pump and the anti-siphon pipe.

7. A method according to claim 6 , wherein the engine comprises a heat exchanger and at least one of the pipes is routed therethrough.

8. A method according to claim 1 , wherein the variable flow valve is operable via a sprung loaded valve, the valve is responsive to the oil pressure in the anti-siphon pipe to increase oil flow therethrough at low engine speeds.

9. A method according to claim 1 , wherein the drive means is an electrical means.

10. A method according to claim 1 , wherein the drive means is a piston.

11. A method according to claim 1 , wherein the engine control system operates the variable flow valve in response to an engine parameter, the engine parameter being from the group comprising engine shaft speed or oil pressure.

12. A method according to claim 1 , wherein the supply of oil provided to the sight glass in the tank is adequate for preventing engine failure for at least 15 minutes.

13. A method of adjusting oil flow to a gas turbine engine comprising providing a gearbox driven by at least one engine shaft, an oil system comprising a pump drivingly connected to the gearbox, an oil tank connected to the pump via a supply pipe, a delivery pipe connecting the pump to the engine for delivery of oil thereto, and an anti-siphon pipe connected between the tank and the delivery pipe to provide an excess oil flow to the engine and an oil flow over a sight glass in the tank, the anti-siphon pipe including a variable flow valve for regulating the flow of oil passing therethrough, the method further comprising the steps of: operating the gas turbine engine to drive the gear box and oil system, thereby supplying oil to the engine; and opening the valve to increase oil flow at low engine speeds to provide adequate oil flow over the sight glass.
