Description

What does a compressor cylinder head do?

This compressor cylinder head acts as the essential cast component seated atop the air brake compressor cylinder block. It functions by sealing the compression chamber from above, allowing workshop technicians to perform a complete rebuild of the unit rather than replacing the entire assembly. This component is vital for maintaining consistent air pressure within the braking system.

Compatibility and engine fitment

This part is compatible with Cummins engines and is specifically engineered to withstand high-pressure environments. It serves as the housing for inlet and discharge valve seats, internal air passages, and cooling cavities, which directly influence the compressor's overall air output and operating temperature.

Installation and maintenance guidance

When performing maintenance, technicians should verify that the cylinder head matches the specific compressor architecture. Proper installation ensures that the seal between the block and the head remains intact, preventing pressure leaks. For optimal performance, check all mounting surfaces and valve seat integrity during the rebuilding process.

System performance and selection

Choosing a high-strength replacement helps maintain the operational efficiency of the air brake system. Ensure compatibility by verifying your current compressor's technical specifications before installation.

OE cross-reference
