ABSTRACT:
A filter device for a cleaning machine includes a plurality of disk-like filter elements accommodated within a casing and connected to a hollow shaft to be rotatable therewith. Arranged between adjacent filtering elements are stationary disks which extend from the casing inner wall towards the shaft. Each disk is provided at its both sides facing the filtering surface of the filtering elements with at least one rib which extends in radial direction and projects towards the filtering surfaces. These ribs cooperate with projections provided on the filtering elements in such a manner that only a narrow gap is defined when the projections pass the stationary ribs during rotation of the filtering elements. Consequently, the ribs and the projections work like vanes of a turbine and cause strong currents to provide a cleaning effect of the filter fabric.
