Bypass turbomachine fitted with bleed system

A bypass turbine engine, comprising

• a first annular flow duct of a primary stream and a second coaxial annular flow duct of a secondary stream extending around the first duct, the turbine engine further comprising a system configured to bleed gas from the primary stream to the secondary stream, said system comprising at least one bleed duct of which one internal end opens onto an outer casing of the first duct and of which one outer end opens onto an inner casing of the second duct, said system further comprising at least one actuator that moves at least one moveable element between a first closed position of the duct and a second bleed and open position of the duct,
• wherein the system further comprises two coaxial rings,
• a perforated internal first ring situated at a level of the outer casing and the perforated internal first ring extending substantially in an extension of the outer casing, and a perforated external second ring mounted to slide circumferentially on the first ring, between the first closed position in which perforations of the first and second rings do not communicate with one another, and the second open position in which the perforations of the first and second rings communicate with one another, the at least one actuator being located between the inner and outer casings outside of the at least one bleed duct defined by the at least one bleed duct.
