Abstract
In a device for separating solid or liquid particles from a stream of gas, there is an aperture of a suction pipe which is substantially directed towards the axis of an impeller. The suction pipe is surrounded by a dust collecting container. To improve phase separation, especially in a vacuum cleaner in which the dust collecting container is fitted upstream of a dust bag, there is an axial aperture in the impeller and/or a straight aperture from the dust collecting container to the impeller. This generates an air vortex in the region of the opening of the suction pipe which carries the particles outwards where they are further transported into the dust collecting container by a secondary vortex induced therein.
