Description
What does a compressor cylinder head do?
The 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. It acts as the top cover, housing the seats for the inlet and discharge valves, internal air passages, and cooling cavities. This component directly governs both the compressor's air output and its running temperature.Common types and configurations
This part is essential for rebuilding air brake compressors in place, offering a cost-effective alternative to replacing the entire unit. Depending on the specific compressor architecture, these heads may be single-cylinder, twin-cylinder, air-cooled with external fins, or water-cooled with jacket channels. Some versions are also supplied with valve plate kits or include an unloader port for governor signal reception.Installation and maintenance guidance
To ensure correct fitment, technicians should always select the head based on the specific compressor's own reference number rather than just the vehicle model. Proper installation requires checking all valve seats and ensuring the sealing surface is free of debris to prevent pressure loss during high-load operation.Selection and fitment advice
Consult your authorized distributor to ensure this component matches the existing compressor architecture in your heavy commercial vehicle.FAQ
What function does a compressor cylinder head serve?
It seals the compression chamber from above and houses the inlet and discharge valve seats, directly controlling air output and temperature.
Can I rebuild my compressor using just this part?
Yes, this component allows workshop technicians to rebuild an existing air brake compressor in place instead of replacing the whole unit.
How do I choose the correct cylinder head?
Selection should always be based on the specific compressor's reference number, as different architectures like single or twin-cylinder vary significantly.
Are there different cooling types available?
Yes, depending on the design, heads can be air-cooled with external fins or water-cooled via jacket channels for high-load stability.
