Latest Patents

Ushikoshi holds a patent for a decompressor designed for internal combustion engines. This decompressor is specifically engineered to facilitate the starting of an engine using a recoil starter. The design allows compression pressure within the cylinder to escape, ensuring that the decompression valve is positioned vertically relative to the crankshaft. This unique arrangement prevents the valve from protruding laterally from the cylinder, thereby avoiding interference with the engine's cowling. The compact layout of the engine is a significant advantage of this design. Additionally, the interlocking mechanism of the decompression valve with the recoil starter is simplified, enhancing usability. The cam at the recoil reel is adjustable based on the type of engine, allowing for variable decompression timing during startup, which optimizes the starting mechanism.
