    摘要: A filtering system (10) is provided for filtering working fluid from a machine (12) and includes a cleanable filter (16) and a centrifuge (82) where filter capacity is too low for a permanent filter yet flow rate is too high for a centrifuge. The system transfers the contaminant storage function from the cleanable filter to the centrifuge. A simple effective centrifuge is provided.

    摘要: A liquid filtering device having a pack of cylindrical filter member discs (70) with an arrangement for reversed, filter flushing flow cycles. An integrally formed filter core (24) is provided comprising tubular nozzled conduits (30a, 30b, 30c) so that water under pressure within the conduits becomes discharged in jet forms to enable free rotation of the filter discs. One-way valve (90) in the form of a funnel shaped rubber sleeve allows the flow of filtered water to the outlet port (20) but impedes the flow of flushing water from the outlet port through the filter member (70) in the direction of the inlet port (16).
