    • Apparatus and method for supplying clean air to a closed vehicle from an ambient source of air polluted with particulate matter. This is accomplished by drawing in air as a hollow cylindrical flow, converting it to the form of a flat sheet of air having components of motion radial and tangential with respect to an axis, deflecting the air by more than 90.degree. to convert it to a conical whirling flow tapering toward the axis while retaining the tangential component of motion, purging from the flow particulate matter discharged centrifugally at the site of the deflection, skimming the conical flow to remove successive outer portions thereof together with the particulate matter centrifugally displaced thereinto, again deflecting the flow by more than 90.degree., in the opposite sense, to convert it to a flat whirling flow retaining the tangential components of motion and having a radially outward component of motion, converting the tangential component to pressure head, and discharging the flow radially as a sheet of air free from particulate polution.
    • 从环境污染颗粒物质的空气源向封闭的车辆提供清洁空气的装置和方法。 这是通过将空气作为中空圆柱形流动来实现的,将其转换成具有相对于轴线径向和切向运动的分量的平板空气的形式,将空气偏转超过90度以将其转换成 圆锥形旋转流朝着轴向渐缩,同时保持运动的切向分量,从在偏转位置离心地排出的流动颗粒物清除,剔除锥形流,以将其连续的外部部分与离心地移动到其中的颗粒物质一起再次 在相反的意义上将流动偏转超过90°,以将其转换成保持运动的切向分量的平坦的旋转流动并具有径向向外的运动分量,将切向分量转换成压力头,并且径向地排出流体 作为一片没有颗粒污染的空气。
