Abstract: Controller for controlling a bleed valve including a first body with an internal cavity connected to an air inlet port and an air outlet port, a second body including a chamber, a mobile member in the cavity and in the chamber, connecting the two bodies. The member is mobile between a position whereby the ports fluidly communicate and a position whereby the ports are isolated, the member further including two pistons housed in the chamber and defining in this chamber at least two spaces. The controller also includes a fluid supply for at least one of the spaces for the purpose of moving the pistons in the chamber.

Abstract: Controller, control actuator and bleed valve including a first chamber for the circulation of a discharge air stream when the valve is open and preventing it when the valve is closed, an inner housing, in which a mobile blocking unit is moved between a position for opening and a position for closing the valve, this unit delimiting, in the inner housing, two chambers, the second chamber including a mechanism for returning the blocking unit to the open position, and the third chamber, being used to be in fluidic connection with the control actuator in order to actuate the blocking unit against the return mechanism, the three chambers being isolated in a sealed manner from one another by way of the blocking unit. The device includes a regulation valve.
