Bleed valve with regulated opening

A device for bleeding an air stream for a turbine engine comprising:

• a controller,
• a control actuator for distributing air connected to the controller, comprising a body comprising an inner cavity connected to an air inlet port and an air outlet port, and comprising a mobile member arranged in said cavity between a position for opening the air outlet port and a position for closing the air outlet port,
• a bleed valve comprising:
• a first chamber intended to make the circulation of a bleed air stream possible when the valve is in an open position and to prevent the circulation of the bleed air stream when the valve is in the closed position,
• an inner housing in which first mobile blocking means is moved between the open position of the valve and the closed position of the valve, and
• an air outlet,
• the first blocking means delimiting, in the inner housing, a second chamber and a third chamber, the second chamber, called upper inner chamber, comprising return means for returning the first blocking means into the open position of the valve, and the third chamber, called lower inner chamber, being configured so as to be fluidly connected to the control actuator in order to actuate the first blocking means against the return means, the three chambers being isolated in a sealed manner from one another by way of the first blocking means,
• the device being characterized in that it comprises a regulation valve comprising:
• an inner space connected to the air outlet port of the control actuator,
• a leakage orifice, and
• second mobile blocking means between a sealed closing position of said leakage orifice and an adjustable opening position of said leakage orifice, so as to create a determined leakage flow and to consequently adjust the pressure within the inner space.
