Stabilized flow control valve
This patent describes, with an internal combustion engine, a crankcase gas flow control device located between the engine crankcase and the engine fuel-air induction. It comprises: a hollow housing with inlet and outlet and portions forming a passage for gas flow therebetween, a converging orifice passage in the flow direction between the inlet and outlet end portions; an apertured member forming an inlet which is supported in the end of the inlet end portion of the housing and defining an inlet therethrough for gas passage; a plurality of radially directed vanes in the inlet aperture to straighten gas flow entering the house; a rod extending through the housing coaxially with the inlet and the orifice passage; a substantially hollow valve element slidably mounted about and axially movable along the rod; a downstream end portion of the hollow valve element being progressively tapered and adapted for movement into the converging orifice as a pressure differential between the inlet and outlet end portions of the housing increases thereby controlling gas flow through the housing.
