Description

What does a compressor cylinder head do?

This compressor cylinder head serves as the critical component that seals the top of the air brake compressor cylinder block. It provides the necessary housing for the inlet and discharge valve seats, ensuring that compressed air is routed correctly through the discharge port while managing heat dissipation during operation.
