This patent describes a reed valve mechanism for use in a fuel/air supply passage of an internal combustion engine. It comprises: a V-shaped reed cage with its apex presented downstream of the direction of the flow through the supply passage, the reed cage having converging side walls with valve ports therein communicating with the supply passage, the side walls having planar external surfaces meeting along the reed cage apex, and reed valves overlaying the valve ports on the downstream sides of the reed cage planar surfaces. The reed cage further having at least one end wall with an interior surface defining a portion of the supply passage and being of curvilinear aeroform contour with respect to the axis of flow through the supply passage to the valve ports. The curvilinear contour is substantially uninterrupted upstream from the valve surface of the reed valve at least to the upstream edges of the reed valve cage, and the upstream portion of the curvilinear aeroform interior surface of the end wall being closer to the flow axis than the downstream portion of the end wall.
