Description

What does a compressor cylinder head do?

A 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. This component is essential for workshop technicians looking to rebuild a compressor in place rather than replacing the entire unit. It governs both the air output and the running temperature of the compressor.

Compatibility and application

This cylinder head is compatible with Knorr-Bremse systems. It is designed to withstand the high-pressure environments found in heavy commercial vehicle air brake systems, ensuring consistent performance for fleet managers and workshop technicians.

Installation and maintenance

When performing maintenance, technicians should verify the specific compressor architecture, as heads may vary between single-cylinder and twin-cylinder configurations. Proper installation ensures that the internal air passages and valve seats remain perfectly aligned to maintain system pressure.

Troubleshooting and selection

Regular inspection of the cylinder head can prevent significant system failures. If leaks or pressure drops occur, checking the seal between the head and the block is a primary troubleshooting step. Consult your authorized distributor.

OE cross-reference
