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 vital for the air brake system, as it houses the seats for the inlet and discharge valves, internal air passages, and cooling cavities. By managing these elements, the cylinder head directly governs both the air output and the running temperature of the compressor. Using a high-strength replacement allows workshop technicians to rebuild a compressor in place rather than replacing the entire unit.
Selection should always be based on the specific compressor architecture. Depending on the requirements, heads may be single-cylinder, twin-cylinder, air-cooled with external fins, or water-cooled with jacket channels. Some variants are supplied with valve plate kits or include an unloader port for governor signal control.
To ensure correct fitment, always verify the specific architecture and port configurations of the existing unit. Consult your authorized distributor to ensure the component matches the compressor's technical requirements.

FAQ
What is the function of a compressor cylinder head?
The cylinder head seals the compression chamber from above and houses the inlet/discharge valve seats and internal air passages to manage air output.
Can I rebuild my compressor using only the cylinder head?
Yes, replacing the cylinder head allows a workshop technician to rebuild a compressor in place rather than replacing the whole unit.
How do I choose the correct cylinder head for my compressor?
Selection must be based on the specific architecture, such as whether it is air-cooled, water-cooled, single-cylinder, or twin-cylinder.
What symptoms indicate a faulty cylinder head?
Issues with air output or abnormal running temperatures often indicate that the head's internal passages or valve seats require attention.
