Description
What does a compressor cylinder head do?
A 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 importance in air systems
This part is essential for workshop technicians looking to rebuild a compressor in place rather than replacing the entire unit. By replacing the head, which is also known as the compressor cover or top cover, technicians can restore the integrity of the compression chamber and ensure optimal performance of the air brake system.Technical role in compression
The component's design directly governs both the compressor's air output and its running temperature. It contains the seats for the inlet and discharge valves, internal air passages, and cooling cavities. Depending on the compressor architecture, these components may be designed for air-cooled or water-cooled operation to handle high-load conditions.Selection and replacement guidance
When selecting a replacement, it is vital to match the specific architecture of the compressor, as heads vary by cylinder configuration and cooling requirements. Consult your authorized distributor to ensure correct fitment for your specific air brake system.FAQ
What is the function of a compressor cylinder head?
It seals the compression chamber from above and houses the inlet and discharge valve seats, directly influencing air output and temperature.
Can this part be used to rebuild an existing compressor?
Yes, this component allows a workshop technician to rebuild a compressor in place instead of replacing the entire unit.
Why are there different types of cylinder heads?
Heads vary based on architecture, such as single-cylinder or twin-cylinder designs, and whether they are air-cooled or water-cooled.
How should I select a replacement cylinder head?
Selection should be based on the specific compressor architecture and its unique reference number to ensure correct valve and port alignment.
