Abstract
Abstract A centrifuging device having particular utility in separating particulate matter from a fluid stream, characterized by a stream jetting orifice and means for directing a stream along a swirling path as it is jetted from the orifice, a particular feature of the device being a resilient lip supported adjacent to the orifice and adapted to vary the effective dimension of the orifice in response to variations occurring in the flow characteristics of the stream for insuring a jetting of the stream over a wide range of streamflow characteristics.
