Description

What does a compressor cylinder head do?

This compressor cylinder head serves as the critical cast component positioned atop the air brake compressor cylinder block to seal the compression chamber. It functions by housing the seats for the inlet and discharge valves, internal air passages, and cooling cavities. This ensures the compressor maintains stable air output and manages operating temperatures during heavy-duty service.

Compatibility and application

This part is specifically compatible with WABCO systems. It allows workshop technicians to rebuild a compressor in place rather than replacing the entire unit, which optimizes maintenance costs for fleet managers. By replacing only the cylinder head, the entire pneumatic system can be restored to optimal performance.

Installation and maintenance

When performing installation, technicians should ensure the sealing surfaces are clean and inspect the valve plate seating. Proper torque application on the mounting bolts is essential to prevent air leaks or thermal stress cracks. Regular inspection of the head helps prevent premature failure of the pneumatic braking system.

Troubleshooting and selection

Check the compatibility list.
