The invention relates to a diffusor system for a motor vehicle, including a diffuser duct, which extends along a virtual duct path and is traversable by flow in a flow direction, having at least one duct bounding surface which is curved about a diffuser curvature axis, the diffuser curvature axis forming an angle with the duct path, and including an output-generating body, which can pivot between two operating positions about a pivot axis, which is orthogonal to the duct path; in a cross-sectional plane, which is orthogonal to the pivot axis, the output-generating body having a profile that generates output in response to approach flow; in an activation operating position, a leading edge of the output-generating body, which is more proximate to the upstream longitudinal end of the diffuser duct, being at a greater distance from the curved duct bounding surface than in an inactivation operating position, which differs from the activation operating position. According to the invention, the pivot axis extends outside of the output-generating body.

    本发明涉及一种用于机动车辆的扩散器装置,所述扩散器装置包括扩散器通道,所述扩散器通道沿着虚拟的通道轨迹延伸并且能够沿流动方向被穿流,扩散器通道具有至少一个围绕扩散器弯曲轴线弯曲的通道限界面,其中扩散器弯曲轴线与通道轨迹形成角度,并且扩散器装置包括输出体,所述输出体围绕垂直于通道轨迹的枢转轴线在两个运行位置之间能够枢转,其中输出体在垂直于枢转轴线的剖平面中具有在入流时产生输出的轮廓,其中在激活运行位置中输出体的更靠近扩散器通道的上游的纵向端部处的前棱边与在不同于激活运行位置的停用运行位置中相比具有距弯曲的通道限界面更大的间距。根据本发明提出,枢转轴线在输出体之外伸展。
