A device (1) comprises filtering means (30) for removing particles from a fluid, which have a particle collecting face (31) for collecting particles during use of the device (1), and a chamber (10) in which a fluid is present and in which the filtering means (30) are arranged. An inlet (11) of the chamber (10) comprises a spouting part (20) which serves for spouting the fluid to be filtered in a direction towards the particle collecting face (31) of the filtering means (30). An arrangement of the spouting part (20) and the particle collecting face (31) with respect to each other is adapted to generate, during operation of the device (1), a rotating flow pattern in the fluid that is present in the chamber (10) under the influence of the flow of the fluid to be filtered, whereby particles can be blown away from the particle collecting face (31). |

1. Device for purifying a fluid, comprising:
filtering means for removing particles from the fluid on the basis of a filtering action, which have a particle collecting face for collecting particles during use of the device, and a chamber in which a fluid is present and in which the filtering means are arranged, wherein the chamber has an inlet for letting in fluid to be filtered, and an outlet for letting out filtered fluid, wherein the inlet of the chamber comprises a spouting part which projects into the chamber and which serves for spouting the fluid to be filtered in a direction towards the particle collecting face of the filtering means, wherein an arrangement of the spouting part and the particle collecting face of the filtering means with respect to each other is adapted to generate, during operation of the device, a rotating flow pattern in the fluid that is present in the chamber under the influence of the flow of the fluid to be filtered, wherein the rotating flow pattern is confined by at least a portion of the particle collecting face of the filtering means for creating a shear force between the fluid in motion and the particle collecting face, wherein a distance (L) between an outlet side of the spouting part and the particle collecting face of the filtering means, measured at a central longitudinal axis of the spouting part, is in a range of 0.5 to 7 times an inner diameter (Ds) of the spouting part, and wherein a cross-sectional area of at least a portion of the chamber between the outlet side of the spouting part and the particle collecting face of the filtering means is at least 3 times as large as a cross-sectional area of the spouting part, in a direction perpendicular to the longitudinal axis of the spouting part. |
