Abstract
(EN)
Herein a cyclone separator (1) is disclosed for separating particles from a flow of fluid. The cyclone separator (1) comprises a housing (5) and at least one guide blade (13) arranged in the housing (5) between an inflow opening (7) and an outflow opening (9). The at least one guide blade (13) extends radially with respect to an axis (11) and is provided with a pitch angle (a0) to provide a cyclone around the axis (11). Each of the least one guide blade (13) comprises a blade portion (15) movably arranged between a first and second position. The blade portion (15) is biased towards the first position, and the blade portion (15) is configured to be moved from the first position towards the second position by the force of the flow of fluid acting on the blade portion (15). The present disclosure further relates to an air intake arrangement (25), a combustion engine (27), and a vehicle (29).

Séparateur à cyclone (1) destiné à séparer des particules d'un flux de fluide. Le séparateur à cyclone (1) comprend un boîtier (5) et au moins une lame de guidage (13) disposée dans le boîtier (5) entre une ouverture d'écoulement entrant (7) et une ouverture d'écoulement sortant (9). La ou les lames de guidage (13) s'étendent radialement par rapport à un axe (11) et sont disposées selon un angle de pas (a0) pour produire un cyclone autour de l'axe (11). Chacune de la ou des lames de guidage (13) comprend une partie lame (15) disposée mobile entre une première et une seconde position. La partie lame (15) est sollicitée vers la première position, et la partie lame (15) est conçue pour être déplacée de la première position vers la seconde position par la force du flux de fluide agissant sur la partie lame (15). La présente invention concerne en outre un agencement d'admission d'air (25), un moteur à combustion (27) et un véhicule (29).
