Jacksonville, North Carolina Patent of the Year – 2024/2025
Stanadyne LLC has been awarded the 2024/2025 Patent of the Year for their innovative fuel injector technology. Their invention, detailed in U.S. Patent No. 11873786, titled ‘Axisymmetric injector hold-down load ring’, introduces a novel approach to securing fuel injectors within internal combustion engines.
The patented load ring features an annular body with an odd-numbered set of resilient arms extending outward. Each arm is designed with a curvature concentric to the annular body, ensuring that force is evenly distributed when the load ring is compressed between the fuel injector and the common rail outlet. This design minimizes off-axis movement of the injector, enhancing stability and performance.
Constructed from resilient steel, the load ring is axially reversible, allowing for flexible installation. Its unique configuration ensures that the injector remains securely positioned, even under the dynamic forces present during engine operation. This advancement promises to improve the reliability and efficiency of fuel injection systems in modern engines.
Stanadyne LLC’s innovative design represents a significant step forward in fuel injector technology, offering enhanced performance and durability for internal combustion engines.
