Q

In order to assure an output near the end of its compression stroke, the pressure developed in the high pressure cylinder of a reciprocating air compressor is __________.

🔍 Key Concepts

• How a reciprocating air compressor builds pressure over the stroke • Relationship between cylinder pressure and discharge line pressure at the discharge (outlet) valve • What must occur for air to actually flow out of the cylinder into the discharge line

💭 Think About

• Think about when the discharge valve will open: what must be true about the pressure in the cylinder compared to the pressure in the discharge line? • Near the end of the compression stroke, as the piston moves toward top dead center, is the cylinder pressure still rising, falling, or staying the same? How does that affect flow into the line? • If the two pressures were exactly equal, what would happen to the direction and rate of flow from the cylinder to the line?

✅ Before You Answer

• Be clear on the difference between instantaneous cylinder pressure and line discharge pressure. • Consider the condition needed for one-way valve (check/discharge valve) operation: when does it open, and when does it close? • Verify whether the cylinder pressure must be slightly different from the line pressure to maintain a positive flow of air into the line.
