This invention is an effective engine induction valve which provides a decrease in engine blowback while maintaining engine power. This valve uses a moveable member made from a heat-setting material, this member being bent into an elliptical curve when the member is in the closed position. This elliptical curve has an included angle at the edge of the member which opens toward the engine, this orientation being beneficial in reducing blowback. Using springs to limit the force attaching the moveable member to the valve body prevents unwanted buckling of this member when exposed to elevated temperature and fuel. An embodiment is described which provides a valve with a uniform frequency response at various operating conditions, especially different temperatures.
