Abstract (en)
[origin: WO2012061880A1] A self-cleaning system for a filter (6.010) includes a filter element (6.038); a filter housing (6.030) with first, second, and third ports (6.032, 6.034, 6.036); the first port being a fluid inlet; the second port being a fluid outlet, and the third port being a recirculation outlet, the first and second ports being on the upstream side of the filter element; the third port being on the downstream side of the filter element; enabling primary and transverse flow through the filter; whereby reverse flow via the third port is used to clean the filter element;the system including a one-way valve (4.040) connected to the second port to inhibit reflux of drain fluid into filter. A recirculation pump (3.014) and a drain pump (3.016) are controlled to periodically drain the lint removed from the filter to the system drain.
