Description

What does a compressor cylinder head do?

This 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.

Compatibility and application

Designed to facilitate efficient rebuilding, this part allows workshop technicians to restore compressor performance without replacing the entire unit. It is compatible with Knorr-Bremse systems and serves as a vital component in the pneumatic braking architecture of heavy commercial vehicles.

Function and technical role

The component functions by housing the seats for the inlet and discharge valves, managing internal air passages, and providing cooling cavities to regulate running temperatures. Maintenance of this part is essential to ensure consistent air output and prevent overheating during sustained high-load operations.

Maintenance and selection

When selecting a replacement, technicians should verify the specific compressor architecture, such as single-cylinder or twin-cylinder configurations, to ensure correct fitment. Consult your authorized distributor.

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 LK1309S1.

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 temperature.
Can this part be used to rebuild an existing compressor?
Yes, this component allows workshop technicians to rebuild a compressor in place rather than replacing the entire unit.
Which systems are compatible with this part?
This part is designed to be compatible with Knorr-Bremse systems used in heavy commercial vehicle air brake compressors.
How should I choose the correct cylinder head?
Selection should be based on the specific compressor architecture (such as water-cooled or air-cooled) and the existing unit's reference number.
What are the OE reference numbers of this part?
20 09 50 directly replaces Knorr-Bremse OE number LK1309S1.
