Abstract:
A centrifugal filter assembly for filtering particulates from a fluid, comprising:a housing;a rotating filter disposed within said housing and rotatable relative to said housing about an axis of rotation, said filter being configured for containing the fluid therein and entrapping the particulates from the fluid, said filter including at least one impingement medium disposed therein, said impingement medium impinging a radially outward flow of the pressurized fluid to be filtered in a radial direction during rotation of the filter, said at least one impingement medium comprising a substantially continuous sheet of material wrapped in a spiral manner about said axis of rotation;a turbine directly attached to said filter, said turbine including a plurality of turbine blades extending generally radially relative to said axis of rotation; anda nozzle having an outlet and being aligned relative to said turbine, whereby a pressurized fluid which is jetted from said nozzle impinges upon said turbine and causes said filter to rotate about said axis of rotation, thereby exerting a centrifugal force on the fluid contained within the filter, said centrifugal force biasing the particulates of the fluid against the filter.
