Abstract
A method for isolating a tank of oil from a downstream portion of an oil supply system for a turbine engine is provided. The oil supply system includes the oil tank and a cutoff valve located between the oil tank and the downstream portion. The cutoff valve is configured to limit a flow of oil towards the downstream portion. The cutoff valve is fluidically linked to a fire extinguishing system by a fluid communication device. The method includes closing the cutoff valve in response to an increase in extinguishant pressure in the fluid communication device.

An assembly for turbomachine comprising:
- a fire extinguishing system configured to release an extinguishing agent into the turbomachine;
- and
- an oil supply system for a turbomachine comprising:
- an oil tank,
- a downstream part located downstream from the oil tank, and
- a cutoff valve located between the oil tank and the downstream part, wherein the cutoff valve comprises an obturator and the cutoff valve is configured to limit/prevent oil flow towards the downstream part,
- wherein the assembly comprises fluid communication means forming a fluid connection between the fire extinguishing system and the cutoff valve, wherein the cutoff valve is configured to close in response to an increase in the pressure of an extinguishing agent in the fluid communication means.
