ABSTRACT:
A direct-flushing fluid filter comprises a filter body disposed within a housing and defining a first plurality of parallel flow paths from the housing inlet to the filtered fluid outlet, and a second plurality of parallel flow paths from the housing inlet to a dirt-purging outlet. Each of the first flow paths includes a filter passageway for removing dirt particles, and an inlet chamber on the inlet side of the respective filter passageway for accumulating the dirt particles. Each of the second flow paths connects the inlet chambers to the dirt-purging outlet while bypassing its respective filter passageway. The filter further includes a valve between the second flow paths and the dirt-purging outlet, which valve is normally closed but is opened to effect a cleaning of the filter by directly flushing the dirt in the inlet chambers through the second flow paths to the dirt-purging outlet.
