Abstract:
A fluid valve is suitable for use with a hydraulic circuit of an item of aircraft equipment. The fluid valve includes a valve body having one inlet, two outlets and a communication channel with an external pressure source. The fluid valve further includes an electric solenoid actuator located in the valve body and having a movable ferromagnetic pilot. A valve member is movable inside valve body to at least partially block a passage between said inlet and one of the two outlets. The valve member at least partially defines first and second cavities. A fixed limiter is disposed within the communication channel such that a displacement of the movable pilot causes a variation in pressure in one of the first and second cavities to produce a force for moving the valve member.
