Abstract
A filter for filtering liquids is proposed, in which the filter fabric along an arcuate path is mounted on a bearing element concomitantly rotating with the filter fabric. The bearing element is constituted by a rotatably mounted ring, which is mounted on a bearing inner ring connected to a wall of the filter. The seal between the bearing inner ring and the rotatably mounted ring is provided by an O-ring, which forms a radial or axial seal. In the case of the present filter, the inlet port is located in the rigid wall and its position and shape can be adapted to the particular requirements.
