Abstract
A backflushed filter assembly, and method of backflushing such a filter. The assembly comprising a filter (1), a backflushing arrangement (2) which generates and directs a backflushing flow to backflush the filter, and a drive arrangement (12) which provides motive power to operate the backflushing arrangement (2). The assembly further comprising a storage and release arrangement which accumulates and stores motive power supplied from the drive arrangement (12) over a first period of time and then releases the stored motive power over a second period to intermittently operate the backflushing arrangement (2) to generate and direct the backflushing flow to backflush the filter. The storage and release arrangement preferably comprises a resilient means (3, 17, 19) which is deformed by the drive arrangement (12) and then released to then drive the backflushing arrangement (2). The drive means (12) may comprise a turbine (14) driven in use by a flow of filtered fluid through the filter and which drives the backflushing arrangement (2).
