🔍 Key Concepts

• Reciprocating air compressor valve operation (how inlet vs discharge valves move during suction and compression strokes) • Direction of normal airflow through the intake filter during proper operation • What happens to airflow direction when a valve fails and allows backflow of compressed air

💭 Think About

• Think about which component failure would cause high-pressure air from the cylinder to be forced back toward the intake filter instead of out to the discharge line. • Ask yourself: during the compression stroke, which valve is supposed to be closed, and what happens if it cannot seal properly? • Consider whether pulsations or system overloading alone would be enough to reverse the airflow direction at the intake filter.

✅ Before You Answer

• Verify which valves (inlet vs discharge) are connected to the intake air filter side of the compressor. • Check which failure mode would cause reverse flow of air from the cylinder back through the intake. • Confirm that system pulsations or loading issues typically affect pressure and vibration, not the direction of flow at the intake filter.
