Abstract
A fluid chamber and method are disclosed for filtering or separating particles. The fluid chamber includes a wall extending between an inlet and outlet to form a fluid chamber interior. The interior converges from a position of maximum cross-sectional area toward the inlet. A groove or a step may be formed on an inner surface of the fluid chamber wall to improve particle separation within the fluid chamber.
