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 an essential component for workshop technicians looking to rebuild a compressor in place rather than replacing the entire unit. By providing the necessary seats for inlet and discharge valves, this part directly governs both the compressor's air output and its running temperature.

Compatibility and application

This component is compatible with Knorr-Bremse systems. It is designed to withstand the high-pressure environments found in heavy commercial vehicle braking systems, ensuring stable air production for various pneumatic operations.

Installation and maintenance

When performing maintenance, technicians should inspect the internal air passages and cooling cavities for any signs of wear or blockage. Proper installation of this head is vital for maintaining correct compression ratios and preventing leaks within the pneumatic circuit.

Troubleshooting and selection

For optimal performance, ensure the surface contact area is clean and free of debris before assembly to maintain a proper seal within the air brake system.

OE cross-reference

16 09 50 (Compressor Cylinder Head) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number LP4970S1.
