Abstract
A liquid filtering device having a pack of cylindrical filter member discs ( ) with an arrangement for reversed, filter flushing flow cycles. An integrally formed filter core ( ) is provided comprising tubular nozzled conduits ( ) so that water under pressure within the conduits becomes discharged in jet forms to enable free rotation of the filter discs. One-way valve ( ) in the form of a funnel shaped rubber sleeve allows the flow of filtered water to the outlet port ( ) but impedes the flow of flushing water from the outlet port through the filter member ( ) in the direction of the inlet port ( ).
