ABSTRACT:
Liquid filter devices, particularly for irrigation systems are known to comprise automatic, periodic reverse-flow rinsing arrangements, whereby water is flushed in the opposite direction to release clogged particles from the filter member. The disclosed devices utilize the reverse, flushing water flow to release the filter member of the device from its normal, stationary position, and rinse it by jets. The jets are also useful to impart a rotatable movement to the filter member. In the case of disc filters, the discs become released and spaced from each other, and individually spin during the rinsing thereof.
