ABSTRACT:
A disk filter of the counter-current flow cleaning type, containing superposed ring-shaped elements (12) form a body (9) of a generally cylindrical shape. The elements are arcuate so as to form between them passages which are arcuate and oblique in relation to the axis of the filter when viewed in a cross section taken along the axis of the filter. Stopping means (19, 20) are provided on the filter elements (12) which abut against the adjacent filter element (12) during the filtering to prevent the filter elements (12) from vibrating, while allowing their vibration to occur when the filter is cleaned by a counter-current flow of liquid.
