The compression spring (code H 55066) in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 engine is a fundamental component that absorbs and distributes force within the valve system. Its robust and flexible design ensures smooth engine operation by maintaining proper pressure and resistance in various mechanical assemblies. Engineered from high-tensile steel, this spring is built to endure high-stress conditions, making it an indispensable part for reliable engine functionality in industrial and marine applications.
