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 integrity of the pneumatic system. By providing seats for the inlet and discharge valves, as well as internal air passages, this part directly governs both the compressor's air output and its running temperature. It allows workshop technicians to rebuild a compressor in place rather than replacing the entire unit, offering a cost-effective solution for fleet maintenance.
Selection depends heavily on the specific compressor architecture. Depending on the requirements of the heavy commercial vehicle, these components may feature water-cooling jacket channels for stable temperatures under high load, or air-cooling fins to release heat into the surrounding air. Some versions are designed for single-cylinder setups, while others are built for twin-cylinder high-output applications.
When performing maintenance, technicians should ensure the head is compatible with the existing cylinder block and valve plate configuration. Proper seating and sealing are vital to prevent pressure loss in the braking system. Consult your authorized distributor to ensure correct fitment for your specific compressor model.

FAQ
What is the function of a compressor cylinder head?
The cylinder head seals the compression chamber from above and contains the seats for inlet and discharge valves, directly controlling air output.
Can I replace just the cylinder head instead of the whole compressor?
Yes, this component allows workshop technicians to rebuild a compressor in place, which is more efficient than replacing the entire unit.
How do I know which cooling type I need?
Selection depends on whether your system uses water-cooled jacket channels for high loads or air-cooled fins to release heat.
What should I check before installing a new head?
Verify that the head matches your compressor's architecture, specifically checking if it requires an unloader port or a specific valve plate configuration.
