Abstract
A gas flow control valve for engine crankcase emissions includes an enclosure and a hollow valve element which is supported on a rod to permit sliding movements in response to a balance of forces produced by gas pressure and a closing spring located within the hollow control valve element. Vanes straighten gas flow to prevent oscillation and rotation of the valve element.
