Abstract
A device applied to regulating the flow rate of air flowing in a rotary shaft of a turbomachine, the shaft including at least one through orifice for passing air. The device at least one shutter member for shutting the orifice and secured to a deformable blade presenting bi-linear behavior, the blade being secured to the shaft and being suitable for deforming under the effect of the centrifugal force that results from the shaft rotating such that the shutter member is suitable for taking up two different positions depending on the speed of rotation of the shaft: one position in which it shuts the orifice; and another position in which it releases the orifice to allow air to pass through.
