Description
The compressor cylinder head is a specialized service component that sits atop the air brake compressor cylinder block to seal the compression chamber from above. It functions as a critical interface where the inlet and discharge valves are seated, directly influencing both the air output volume and the operating temperature of the entire compressor unit.
This component is essential for workshop technicians performing in-place rebuilds of air brake compressors, allowing for extended service life without replacing the entire unit. Depending on the specific compressor architecture, these heads may feature different configurations, such as single-cylinder or twin-cylinder designs, and may include integrated cooling cavities or unloader ports to manage thermal loads and governor signals.
When performing maintenance or repairs, it is vital to ensure the new head matches the specific compressor architecture. Selection should always be based on the compressor's own reference number, as different engine options within the same vehicle model may require different head configurations, such as water-cooled or air-cooled variants.
Consult your authorized distributor to ensure correct fitment for your specific heavy commercial vehicle braking system.

FAQ
What is the function of a compressor cylinder head?
The cylinder head seals the compression chamber and provides the necessary seating for inlet and discharge valves, directly governing air output and temperature.
Can I use any cylinder head for my air brake compressor?
No, selection must be based on the specific compressor reference number, as designs vary between single-cylinder, twin-cylinder, and different cooling types.
Why should I replace a cylinder head instead of the whole compressor?
Replacing just the cylinder head allows a workshop technician to rebuild an existing unit in place, which is a cost-effective way to restore performance.
What symptoms indicate a faulty cylinder head?
Issues with air output volume or abnormal operating temperatures often indicate that the internal valve seats or sealing surfaces within the head are compromised.
