摘要： A self-cleaning filter assembly includes a cylindrical cartridge filter element supported on a coaxially mounted hydrodynamic bearing for rotation of the cartridge filter element about its longitudinal axis. The cylindrical cartridge filter element includes a hollow interior for receiving filtered water. A water spray manifold is provided proximate to the cartridge filter element and includes spray nozzles for providing a water spray capable of rotating the cartridge filter element about its longitudinal axis. A diverter valve receives flow of water to be filtered. With the diverter valve in a first position, the received flow of water submerges the cartridge filter element, with the filtered water received at the hollow interior of the cartridge filter element. With the diverter valve, in a second position, the received flow of water is provided to the water spray manifold causing it to fill under pressure. Water sprays out of the spray nozzles directed at the cartridge filter element causing it to rotate about its longitudinal axis. The water spray cleans the cartridge filter element as it rotates. Additionally, with the diverter valve in its second position, a portion of the water flow to the water spray manifold is tapped off and provided to the hydrodynamic bearing to provide a film of water as the load bearing component allowing rotation of the cartridge filter element thereon.
