Latest Patents
One of Nakazawa's latest inventions is the **Combined Oil Control Ring**. This innovative design aims to prevent the separate rotation of side rails over extended periods, even under conditions of fretting fatigue. The oil control ring includes seating tabs of a spacer expander, which are configured with substantially longitudinal projections and recesses on their side-rail-pushing surfaces. The design further features a bottom surface wider than the circumferential length of the top surface for each projection, creating a bulging shape that efficiently connects the top surface to the recess surface.
His other notable patent, the **Spacer Expander**, complements the functionality of the combined oil ring. This invention introduces a spacer expander installed between upper and lower side rails, which includes a series of axially protruding inner peripheral portions along its inner surface. These protrusions press against the inner peripheral surface of the side rails, ensuring a secure fit. The outer side of the spacer expander is also designed with multiple slits and connecting portions that hold axially protruding outer peripheral protruding portions, enhancing the overall stability and performance of the assembly.
