A retainer member engaging the large end of the conical spring receives therethrough the first and second draw bars to prevent binding of the spring assembly and to translate the conical spring force to uniform linear forces acting through the first and second draw bars to appropriately tension the filter sleeve and to permit controlled flexure during cycling from a filtering to a cleaning operation.
