Beschreibung
Zusammenfassung:	An air intake swirler (100, 200) for a turbomachine injection system (70) comprises an upstream wall (102, 202) and a downstream wall (104, 204), both of revolution about an axis (44) of the air intake swirler, and fins (106, 206) distributed about the axis (44) and connecting the upstream wall to the downstream wall so as to delimit, between the upstream wall and the downstream wall, air inlet channels (108, 208) each having an inlet (110, 210) and an outlet (112, 212).The swirler comprises two aerodynamic deflectors (120, 220) that respectively extend the downstream walls (104, 204) radiallyoutward and that have a concavity oriented upstream. The aerodynamic deflectors extend radially facing the respective inlets (110, 210) of the air inlet channels and thus make it possible to limit the loss of pressure of the air supplied to the air inlet channels (108, 208). 用于涡轮机喷射系统(70)的进气旋流器(100，200)包括围绕进气旋流器的轴线(44)旋转的上游壁(102，202)和下游壁(104，204)，以及翅片(106，206)，该翅片围绕轴线(44)分布并且将上游壁连接到下游壁以便在上游壁和下游壁之间界定出空气入口通道(108，208)，每个空气入
