Latest Patents
Yamakawa holds 1 patent for his invention titled "Method of hardening a valve face of a poppet valve." This patent describes a process in which a lobe is formed in the valve head of a poppet valve. The lobe features a vertical section shaped like an isosceles triangle, with the vertex positioned in the middle. By pressing this lobe into a bore of a die, it undergoes plastic deformation, resulting in the formation of a valve face that effectively contacts the valve seat. This method ensures suitable airtightness between the valve face and the valve seat, enhancing the overall efficiency of the engine.
