ABSTRACT:
A centrifugal oil filter for removing contaminant particles from a pressurized fluid medium includes a cylindrical drum concentric with and fixedly secured to a rotational shaft, with an annular disc being disposed within and rotatable with the drum. The disc is centered within the drum and spaced from the internal circumferential surface of the drum so as to partition the drum into two radial passageways interconnected at said internal circumferential surface. The latter is of irregular configuration to define an annular collection zone for collecting contaminant particles centerfuged outwardly by rotation of said drum. Pressurized fluid medium is provided to one radial passageway, flows past the annular collection zone where the contaminant particles are centerfuged and entrapped in the irregular internal circumferential surface of the drum, after which the pressurized fluid medium is forced radially inwardly through the other radial passageway and out of the centrifugal oil filter.
