A hydraulic filter is provided with means for effectively cleaning its mesh filtering element during a flushing or 'blow-down' cycle, wherein unfiltered liquid is passed rapidly along the surface of the tubular mesh to be exhausted from the filter substantially without passing through the mesh. The filter assembly includes at its inlet end a flow-restricting orifice for imparting turbulence to the liquid as it enters the interior of the tubular filtering mesh. The turbulence helps clean the mesh directly, and also tends to induce a fluttering of the mesh during blow-down, which adds to the cleaning effect. In addition, the mesh sleeve is of a somewhat tapered or frustoconical configuration which helps induce it to break away from a rigid retaining screen and helps promote fluttering during blow-down to further the cleaning action, as well as tending to deposit filtrate toward the downstream end during filtration, thereby extending the filtering cycle.
