Flow enhancer for reed inlet valves

Patent ·
OSTI ID:6096670
A flow enhancer insert is described for use in a roof prism shaped reed valve inlet frame of a two cycle internal combustion engine which consists of: an annular ring secured into an upstream portion of the reed valve inlet frame adjacent to a carburetor duct leading to the reed valve inlet frame. The ring is flush with an upstream opening face of the reed valve inlet frame and matching a downstream contour of the carburetor duct to an interior contour of the reed valve inlet frame; and two substantially triangular wedges each shaped so as to extend downstream from opposite sides of the annular ring and substantially to an interior apex of the reed valve inlet frame and each wedge to substantially cover an entire interior surface of each of two parallel triangular surfaces of the reed valve inlet frame with each wedge tapering outwards from the interior of the annular ring to cause substantially zero wedge thickness at an apex of each wedge and each wedge being attached at its base to the annular ring.
