Description
A compressor cylinder head is the cast service component that sits on top of an air brake compressor's cylinder block and seals the compression chamber from above.
This component is essential for maintaining the pneumatic integrity of the air brake system. By providing seats for the inlet and discharge valves, it directly governs both the compressor's air output and its running temperature. Using high-strength components ensures reliable sealing under high-pressure conditions.
Selection should always be based on the specific compressor architecture to ensure correct fitment. Depending on the design, these heads may be single-cylinder or twin-cylinder types, and can be either air-cooled with external fins or water-cooled with internal jacket channels.
When performing maintenance, technicians should inspect the valve seats and internal air passages for any signs of wear. Replacing only the cylinder head allows for a cost-effective rebuild of the compressor unit rather than a full replacement of the entire assembly. Consult your authorized distributor.

FAQ
What is the function of a compressor cylinder head?
The cylinder head seals the compression chamber from above and houses the inlet and discharge valve seats, governing air output and temperature.
Can I choose a head based on vehicle model alone?
No, because different engine options may require different compressors, you must select based on the specific compressor architecture or reference.
What are the common types of cylinder heads?
They vary by design, including single or twin-cylinder configurations, and can be either air-cooled or water-cooled for different thermal needs.
How can I identify if a replacement is needed?
Technicians should look for signs of poor air output or temperature instability, which may indicate issues with the valve seats or internal passages.
