ABSTRACT:
The present invention provides improved multiple stage reed valve construction for internal combustion engines. The reed valves comprise first stage reed valves with multiple ports in the first stage reed valve. Beams having a smoothly shaped curve from the base of the first stage reed valve to the apex thereof and narrowing toward the apex separate adjacent ports. The reed valves of the present invention provide significant improvements in engine operation.
