🔍 Key Concepts

• Operation of an unloading system on a reciprocating air compressor • Difference between mechanical friction load and air/compression load • What happens to compressor discharge pressure and speed during normal vs starting conditions

💭 Think About

• Ask yourself: when a motor first starts, what kind of load is the unloading system trying to avoid placing on it? Is it friction, or the load of compressing air? • Think about what physically changes inside the compressor when it is "unloaded"—are the valves being held open so no real compression occurs, or is the machine actually running faster or building more pressure? • Consider which choice describes a condition where the compressor is still turning, but not really doing compression work on the air.

✅ Before You Answer

• Identify which option describes the motor driving the compressor with no compression work, only internal drag/friction. • Eliminate any choices that talk about increasing pressure or speed, because an unloading system’s purpose is typically to lighten the load, not increase it. • Focus on the choice that best matches: compressor can rotate normally but is effectively not compressing air during starting or idling.
