  "textContent": "A flow discharge device, such as a bleed assembly in a gas turbine engine, comprises a discharge outlet member 38 having a skirt 44 which is accommodated telescopically in a housing 36 so as to be displaceable with respect to a wall 27 of a duct 22 from a retracted position ( Figure 2 ) in which slots 48 in the skirt 44 lie outside the duct 22, and an extended position ( Figure 3 ) in which the slots 48 open into the duct 22 for the discharge of a secondary fluid into the flow in the duct 22. The discharge outlet member 38 is moved to the extended position by the pressure of the secondary fluid acting on a silencer element 46. A spring 52 returns the discharge outlet member to the retracted position when the flow of the secondary fluid is terminated.",
