Abstract
A centrifugal oil filter includes a housing having a rotatable bowl disposed in a first fluid chamber and rotatably disposed about a shaft extending through the first fluid chamber. The rotatable bowl has a partition dividing the rotatable bowl into upper and lower portions. A port is formed in the partition so that the fluid flow within the rotatable bowl is directed to a pair of nozzles which act to rotate the rotatable bowl responsive to fluid flow therethrough. The port draws fluid from near the top of the rotatable bowl. Foreign particles are held along the inner wall of the bowl and the top of the partition protecting the particles from the fluid flow within the rotatable bowl.
