Description

What does a compressor cylinder head do?

This compressor cylinder head serves as the primary sealing component situated on top of the air brake compressor cylinder block. It functions to seal the compression chamber from above, allowing workshop technicians to rebuild compressors in place rather than replacing the entire unit. This component is essential for maintaining consistent air output and regulating running temperatures within the pneumatic system.

Compatibility and function

This part is compatible with Cummins engines and is often referred to in workshops as a compressor cover, top cover, or cylinder cover. It contains the necessary seats for the inlet and discharge valves, internal air passages, and specific cooling cavities required for efficient operation.

Installation and maintenance
