Description

What does a cylinder head do?

The cylinder head serves as the primary sealing component sitting atop the compressor cylinder block. Its main role is to seal the compression chamber from above, allowing workshop technicians to rebuild an existing compressor unit rather than replacing the entire assembly. This part directly influences both the air output and the thermal regulation of the system.

Compatibility and application

This component is designed to be compatible with Knorr-Bremse systems. It is an essential part for maintaining the pressure integrity of air brake compressors in heavy commercial vehicles. Professionals can rely on this high-strength component to restore optimal performance to the pneumatic braking system.

Installation and maintenance

When performing maintenance, technicians should inspect the internal air passages and valve seats within the head. Proper installation ensures that the cooling cavities function correctly, preventing overheating under sustained high loads. Always verify that the port configurations match the existing compressor architecture during the rebuilding process.

Troubleshooting guidance

Selecting the correct cylinder head is vital for system stability. If air leakage or temperature spikes occur within the pneumatic circuit, a thorough inspection of this component is recommended. 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 LK1303S1.
