Description

What does a cylinder head do?

This cylinder head acts as the critical seal positioned atop the air brake compressor cylinder block to secure the compression chamber. By managing internal air passages and valve seats, this component directly influences both the air discharge output and the operating temperature of the compressor assembly.

Compatibility and application

Designed for heavy commercial vehicle applications, this part allows workshop technicians to perform precise rebuilds of existing units. It is compatible with Knorr-Bremse systems and ensures the integrity of the pneumatic circuit during high-pressure operation.

Installation and maintenance

When replacing this component, technicians should inspect the valve seats and cooling cavities to ensure no blockages exist. Proper seating is essential to maintain pressure stability within the pneumatic system and prevent leaks in the compression chamber.

Selection guidance

Consult your authorized distributor to ensure correct fitment for your specific compressor architecture.

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 LK1503S1.

FAQ

What is the function of a cylinder head in an air compressor?
The cylinder head seals the compression chamber from above and contains the inlet and discharge valve seats, directly governing air output and temperature.
Can this part be used to rebuild an existing compressor?
Yes, this service component allows a workshop technician to rebuild a compressor in place rather than replacing the entire unit.
What should be checked during installation?
Technicians should verify the integrity of the internal air passages and ensure the valve seats are clean to maintain proper pneumatic pressure.
Is this compatible with Knorr-Bremse systems?
Yes, this component is designed to be compatible with Knorr-Bremse systems used in heavy commercial vehicle braking applications.
What are the OE reference numbers of this part?
20 09 50 directly replaces Knorr-Bremse OE number LK1503S1.
