Latest Patents

One of Nakagawa's latest patents is an inner air vent system for float chambers in carburetors. This innovative system prevents accidental fuel flush from the float chamber into the venturi tube of the carburetor, especially when the vehicle is on a steep slope or rough surface. The design includes an air passage that is axially defined in the mounting bosses of the air cleaner, air intake pipe, and carburetor, ensuring that the upper opening of the air passage remains above the fuel level in the float chamber. This arrangement minimizes the risk of fuel flow into the carburetor venturi tube during extreme vehicle tilts. Additionally, the system is simple in structure and can be integrated into small, lightweight engines without significant increases in assembly costs.

Another significant patent by Nakagawa is 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 ensures that oil mist circulates in one direction, preventing backflow from the crank chamber to the separating chamber, even when the engine is inclined.
