Patent ID: 7655073

Claim:
An apparatus for removing oil particles in a flow from a crankcase responsive to changing flow conditions, comprising: a cylindrical wall defining a first flow path extending along an axis, the first flow path being fluidly connected to an inlet, the wall further defining a plurality of radially extending apertures, the radially extending apertures defining a second flow path toward an impactor wall, wherein the impactor wall is spaced apart from the cylindrical wall by an annular gap, the annular gap defining a third flow path that is fluidly connected to an outlet; and, a variable flow actuator that translates axially within the first flow path between a first position and at least a second position, wherein movement of the actuator from the first position to the second position increases at least one of size and number of the radially extending apertures fluidly connecting the first flow path to the third flow path.
