The compression spring with code number H 16173 is a vital energy-storing component within the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 diesel engine. Designed to absorb and release mechanical force, this spring is used in various assemblies, particularly where controlled motion or force regulation is essential. Its coiled structure resists compressive loads, helping maintain pressure or tension between components in valve gear or control systems. Engineered from high-strength steel, it ensures durability and consistent performance under cyclic stress, playing a key role in preserving the precision and reliability of the engine’s moving parts.
