Description

What does a compressor cylinder head do?

This compressor cylinder head is the cast service part that closes off the top of an air brake compressor's cylinder block and carries the seats for the inlet and discharge valves. It holds the compressed air without leaking, routes it out through the discharge port, and helps manage compression heat from the body.

Vehicle and engine compatibility

This component is specifically designed for fitment in Volvo trucks and buses, including models such as the FL12, F12, FH12, NL12, NH12, B10M, B10B, and B12. It supports various engine configurations including D10A, D12A, TD102, TD103, TD122, and TD123 to ensure precise pneumatic performance.

Installation and maintenance

When performing maintenance on the air brake system, technicians should inspect the cylinder head for signs of surface erosion or valve seat wear. Replacing this part allows for a comprehensive rebuild of the compressor assembly without requiring a full unit replacement. Ensure all mating surfaces are clean during installation to maintain proper sealing.

System performance

Selecting the correct head is vital for maintaining stable air pressure in heavy commercial vehicle braking systems.
