🔍 Key Concepts

• How the unloader works in a low pressure air compressor and what happens if it malfunctions • What conditions actually affect cylinder inlet valves directly (pressure, temperature, load) versus what mostly affects other parts of the system • The relationship between moisture in the receiver and valve operation in the compressor cylinders

💭 Think About

• Ask yourself: which option acts closest to the cylinder inlet valve and can directly change how and when it opens or closes? • Which choice would most likely create abnormal pressure or loading right at the inlet valve, leading to damage or failure? • Which options mainly affect other parts of the system (drive alignment, receiver condition, clearance) rather than the inlet valve itself?

✅ Before You Answer

• Identify which component has a direct control or influence over when inlet valves see pressure or are relieved of pressure • Eliminate any choice that mainly affects only the drive train or receiver storage, not the cylinder’s own valve operation • Consider how a mechanical failure in each listed component would realistically show up in compressor behavior and whether that would stress the inlet valves
