Key Functions of the 3115359300 Diaphragm

In Atlas Copco rock drill systems, diaphragms serve as a critical interface between air or oil chambers. The 3115359300 DIAPHRAGM ATLAS COPCO acts as a flexible barrier that isolates fluid zones while allowing controlled movement in response to pressure changes. It’s commonly used in dampening systems, accumulators, and valve regulators in rock drills, where it helps:

• Maintain pressure equilibrium

• Isolate fluid from contaminants

• Absorb shock and vibration from percussion mechanisms

• Improve operational smoothness during high-load cycles

This specific part is constructed from a high-resilience elastomer that withstands repetitive motion, hydraulic shock, and temperature fluctuations common in mining and tunneling applications.
