Description
A cylinder head acts as the cast service component that sits on top of an air brake compressor's cylinder block, sealing the compression chamber from above. This part is essential for workshop technicians performing in-place rebuilds, allowing for the restoration of compressor performance without requiring a complete unit replacement. It serves as the critical interface where air passages and valve seats are located.
This specific component is compatible with Knorr-Bremse systems. It is designed to maintain pressure integrity and manage thermal loads during high-demand operation. By replacing only the cylinder head, service professionals can effectively address leaks or worn valve seats within the pneumatic system.
When performing installation, ensure the cylinder block surface is clean and free of debris. The head must be seated correctly to maintain a proper seal within the compression chamber. Regular inspection of the valve seats and internal air passages is recommended to prevent pressure drops or overheating during heavy commercial vehicle operation.
Consult your authorized distributor for exact fitment verification.

FAQ
What is the function of a compressor cylinder head?
The cylinder head seals the compression chamber from above and houses the inlet and discharge valve seats, directly governing air output and running temperature.
Can this part be used to rebuild an existing compressor?
Yes, this component allows a workshop technician to rebuild a compressor in place by replacing the worn top cover rather than replacing the entire unit.
Is this component compatible with Knorr-Bremse?
This cylinder head is designed to be compatible with Knorr-Bremse systems used in heavy commercial vehicle air brake assemblies.
What symptoms indicate a faulty cylinder head?
Symptoms may include air leaks from the top of the compressor, loss of air pressure, or abnormal running temperatures due to compromised sealing.
What are the OE reference numbers of this part?
12 11 50 directly replaces Knorr-Bremse OE number LK3808S1.
