特别用于内燃机的曲轴箱通风的油分离装置
摘要：
本发明涉及一种特别适用于内燃机的曲轴箱通风的油分离装置(1)，所述油分离装置具有沿着纵轴(10)轴向延伸的空心体(11)，携带油(12)的气流(13)能够流过所述空心体(11)，其中，在所述空心体(11)中形成有油分离环(14)，所述气流(13)能够流动并撞到所述油分离环(14)。根据本发明，在所述空心体(11)中布置有大致旋转对称的导流件(15)，所述导流件(15)具有位于所述纵轴(10)上的导流突出部(16)以及沿着下游方向径向延伸的导流轮廓(17)，使得气流(13)能够从所述导流件(15)的周围流过，所述导流轮廓(17)与所述空心体(11)的内侧(11a)之间的气流(13)能够加速撞击所述油分离环(14)。
摘要（英）：

The invention relates to an oil-separating device (1), in particular for a crankcase ventilation system of an internal combustion engine, comprising a hollow body (11), which extends axially in the direction of a longitudinal axis (10) and through which a gas flow (13) laden with oil (12) can flow, wherein an oil-separating ring (14) against which the gas flow (12) can flow is inserted in the hollow body (11). According to the invention, a substantially rotationally symmetrical flow-conducting body (15), which has a flow nose (16) lying in the direction of the longitudinal axis (10) and a flow contour (17) that grows radially in the downstream direction, is arranged in the hollow body (11), such that the gas flow (13) can flow around the flow-conducting body (15) and such that the gas flow (13) can be accelerated between the flow contour (17) and the inside (11a) of the hollow body (11) before hitting the oil-separating ring (14).
