Abstract
Drained fluid evacuation stub (16) for a propulsion assembly (10), comprising a drained fluid storage cavity and at least one orifice (32) for evacuation of the fluids contained in said cavity, characterized in that it comprises means (36, 38) for detecting a pressure difference with the exterior of the stub and a component for purging the cavity which is movable between a first closed position of the evacuation orifice and a second release position of the orifice, the component being configured to move from the first to the second position when the pressure difference is greater than or equal to a predetermined value.
Claims10
Stub for discharging drained fluids for a propulsion unit, this stub comprising a cavity for storing the drained fluids and at least one orifice for discharging the fluids contained in the storage cavity, wherein it comprises means for measuring a difference in pressure outside the stub and a member for draining the storage cavity, this member being able to move between a first position of closing the discharge orifice and a second position of releasing this orifice, the member being configured so as to move from the first to the second position when said difference in pressure is greater than, or equal to, a predetermined value.
