What does a compressor cylinder head do?

This compressor cylinder head acts as the critical component that closes the top of an air brake compressor cylinder block, providing the necessary seats for inlet and discharge valves. It is engineered to hold compressed air securely without leakage while facilitating heat dissipation from the compression process. Built with high-strength components, it ensures long-term reliability under heavy-duty operating conditions.

Compatible vehicles and engines

This part is widely used in various heavy commercial vehicles including Yutong ZK6118, Zhongtong LCK6118, KamAZ 4308, and Ford Trucks Cargo models. It is also fitted to Dongfeng Captain, Iveco Bus Metro, and Volkswagen Constellation trucks equipped with ISBe or ISLe engines. The component maintains optimal performance across diverse fleets including KamAZ 6520 and Dongfeng Kinland.

Installation and maintenance

For proper maintenance, technicians should inspect the cylinder head for signs of thermal stress or surface erosion during routine inspections. When installing this component, ensure that all sealing surfaces are clean and that the valve seats are properly seated to prevent air pressure drops within the pneumatic system. This allows for a professional rebuild of the compressor unit in place.
