Latest Patents
One of Nii's latest patents is for an inner air vent system for float chambers in carburetors. This system prevents accidental fuel flush from the float chamber into the venturi tube, especially when vehicles are operating on steep slopes or rough surfaces. The design includes an air passage that is axially defined in the mounting bosses of the air cleaner, air intake pipe, and carburetor. This arrangement ensures that even in extreme vehicle tilts, fuel flow into the carburetor venturi tube is unlikely, as the air passage's upper opening remains above the fuel level in the float chamber. Additionally, this system is simple in structure and can be incorporated into small, lightweight engines without significant increases in assembly costs.
Another patent by Nii involves a lubricating system for horizontal cylinder overhead valve engines. This system features a pair of passages that connect a crank chamber, which reserves oil, to an air-oil separating chamber that houses the mechanism for actuating overhead valves. The breather passage allows fluid to flow solely toward the air-oil separating chamber, while a large oil-circulating resistance is created in the oil-returning passage. This design effectively circulates an oil mist in one direction, preventing oil from flowing back into the separating chamber even when the engine is inclined.
