The invention relates to an intermediate housing hub () comprising a discharge stream conduit () having a given length (L), and discharge fins () extending in the discharge stream conduit () and having a given chord length (L), the chord length (L) of at least one of the discharge fins () being at least equal to 50% of the length of conduit (L).

Intermediate housing hub comprising discharge flow guiding channels formed by the discharge fins

The disclosure relates to a flow deflector for a discharge valve system of a double flow turbomachine compressor. The flow deflector comprises a wall provided with a plurality of ejection channels positioned to discharge a discharge air flow. The ejection channels are arranged in rows along aligned directions, substantially parallel to an axial plane of the deflector. The ejection channels of each row are oriented at a defined angle between a normal line to the wall and axes of the ejection channels, and decreasing between an upstream edge and a downstream edge of the wall, as defined according to the direction of movement of the air flow.

Flow deflector for a discharge valve system, discharge valve system and turbomachine comprising such a discharge valve system

A discharge valve system of a bypass turbine engine compressor includes a flow deflector. The flow deflector has a wall provided with a plurality of ejection channels configured to discharge a discharge airflow from the compressor in a duct of the turbine engine in which an airflow circulates. The ejection channels are disposed in a plurality of concentric rows around a center and are oriented at an angle defined between a straight line normal to the wall and the axes of the ejection channels. The angle of the ejection channels vary by increasing from the peripheral edge towards the center of the wall so that the discharge airflow passing through the ejection channels is guided in a gyratory movement around the center.
