Fluid flow control valve equipped with an electric actuator and system including such a valve

A ventilation system for an aircraft engine comprising:

• one or more air control valves, each of said valves comprising:
• a valve body comprising a fluid inlet, a fluid outlet, and a fluid flow duct extending in a longitudinal direction between the fluid inlet and the fluid outlet,
• a closing member arranged in said fluid flow duct and configured so as to be able to have an open position, in which it allows the fluid flow to flow freely in said flow duct, and a closed position, in which it prevents, at least partially, the flow of fluid in said flow duct between said fluid inlet and said fluid outlet,
• an electric actuator of said closing member that is suitable for being able to control the position of said closing member in said fluid flow duct,
• characterized in that said electric actuator is arranged at least partially in said fluid flow duct such that it can be cooled by said fluid flowing between the fluid inlet and the fluid outlet of said valve body and in that said closing member comprises two conjugate concentric elements:
• a fixed element relative to said valve body and
• a valve core comprising a rotary element relative to said fixed element and which is controlled by said electric actuator.

An air or rail transport vehicle comprising:

• at least one propulsion engine,
• a cabin and
• at least one air-conditioning system for said cabin, wherein the air-conditioning system for the cabin is the air-conditioning system comprising at least one valve, said valve comprising a valve body comprising:
• a fluid inlet, a fluid outlet, and a fluid flow duct extending in a longitudinal direction between the fluid inlet and the fluid outlet,
• a closing member arranged in said fluid flow duct and configured so as to be able to have an open position, in which it allows the fluid flow to flow freely in said flow duct, and a closed position, in which it prevents, at least partially, the flow of fluid in said flow duct between said fluid inlet and said fluid outlet,
• an electric actuator of said closing member that is suitable for being able to control the position of said closing member in said fluid flow duct,
• characterized in that said electric actuator is arranged at least partially in said fluid flow duct such that it can be cooled by said fluid flowing between the fluid inlet and the fluid outlet of said valve body and in that said closing member comprises two conjugate concentric elements:
• a fixed element relative to said valve body and
• a valve core comprising a rotary element relative to said fixed element and which is controlled by said electric actuator.
