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 workshop technicians performing in-place rebuilds of air brake compressors, allowing for efficient maintenance without replacing the entire unit. It functions as the top cover, housing the seats for the inlet and discharge valves, as well as the internal air passages and cooling cavities necessary for stable operation.
The cylinder head is compatible with Knorr-Bremse systems. When selecting a replacement, it is vital to match the specific compressor architecture, as these components vary based on whether the unit requires air or water cooling or features specific unloader ports.
Consult your authorized distributor to ensure correct fitment for your specific compressor model.
