Abstract
(EN)
Example filters are disclosed herein. In an example, the filter includes a housing including a central axis, an inlet, and an outlet. The central axis extends perpendicularly to a fluid flow direction at the outlet. In addition, the filter includes an outlet flow path defined within the housing that extends angularly about the central axis to the outlet. Further, the filter includes a first plurality of vanes extending from a radially outer surface of the outlet flow path.

Des exemples de filtres sont décrits dans la présente invention. Dans un exemple, le filtre comprend un boîtier comprenant un axe central, une entrée et une sortie. L'axe central s'étend perpendiculairement à une direction d'écoulement de fluide au niveau de la sortie. De plus, le filtre comprend un trajet d'écoulement de sortie défini à l'intérieur du boîtier qui s'étend angulairement autour de l'axe central jusqu'à la sortie. En outre, le filtre comprend une première pluralité d'aubes s'étendant à partir d'une surface radialement extérieure du trajet d'écoulement de sortie.
