Abstract
A flow discharge device, such as a bleed assembly in a gas turbine engine, comprises a discharge outlet member having a skirt which is accommodated telescopically in a housing so as to be displaceable with respect to wall of a duct from a retracted position in which slots in the skirt lie outside the duct, and an extended position in which the slots open into the duct for the discharge of a secondary fluid into the flow in the duct. The discharge outlet member is moved to the extended position by the pressure of the secondary fluid acting on a silencer element. A spring returns the discharge outlet member to the retracted position when the flow of the secondary fluid is terminated.
