Description

What does a cylinder head do?

This compressor 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. It is a critical part of the compressor assembly, designed to allow workshop technicians to rebuild a unit in place rather than replacing the entire compressor assembly. Inside the head, the seats for the inlet and discharge valves, internal air passages, and cooling cavities are located, directly governing both air output and running temperature.

Compatibility and application

This component is compatible with Knorr-Bremse systems and is suitable for various heavy commercial vehicle applications. Selection should always be based on the specific compressor architecture to ensure correct fitment with the existing cylinder block.

Installation and maintenance guidance

When replacing this part, technicians should inspect the valve plate and gaskets to ensure a proper seal within the compression chamber. Maintaining clean mounting surfaces is essential to prevent air leaks during high-pressure operation. Consult your authorized distributor for fitment confirmation.

OE cross-reference

20 09 50 (Compressor Cylinder Head) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number LK1304S1.

FAQ

What is the function of a compressor cylinder head?
It seals the compression chamber from above and houses the inlet and discharge valve seats, regulating air output and temperature.
Can this part be used to rebuild an existing compressor?
Yes, this component allows a workshop technician to rebuild a compressor in place instead of replacing the whole unit.
How do I ensure correct compatibility?
Selection should always be based on the specific compressor architecture and reference numbers to match the existing cylinder block.
What are common symptoms of a faulty cylinder head?
Improper air output or irregular running temperatures often indicate issues with the internal air passages or valve seats.
What are the OE reference numbers of this part?
20 09 50 directly replaces Knorr-Bremse OE number LK1304S1.
