Description

What does a 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.

Function and system role

This component is essential for rebuilding compressors in place rather than replacing the entire unit. It contains the seats for the inlet and discharge valves, internal air passages, and cooling cavities, which directly govern both the air output and the running temperature of the compressor.

Maintenance and installation

The part is designed to withstand heavy-duty operating conditions, maintaining a tight seal within the pneumatic system. It is vital for maintaining consistent pressure levels in heavy commercial vehicle braking systems.

Troubleshooting and selection

Maintenance technicians should inspect the cylinder head and valve seats during every compressor overhaul to prevent air leaks. Check compatibility with Knorr-Bremse systems to ensure correct fitment during installation.

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 LP4983S1.
