A compressor that has a broken Reed valve will cause these symptoms...

• A. High suction pressure and high discharge pressure
• B. Low suction pressure and high discharge pressure
• C. Low suction pressure and low discharge pressure
• D. High suction pressure and low discharge pressure

Answer: (D)

Reed valves act as one-way gates in the compressor, letting gas flow from suction into the cylinder and then sealing to keep high‑pressure discharge gas from flowing back into the suction side. If a reed valve is broken, it can’t seal properly, so high‑pressure discharge gas leaks back into the suction path during compression. This backflow raises the suction side pressure because you’re pushing hot, pressurized gas into the intake network. At the same time, some of the compressor’s effort is wasted pushing gas back through the damaged valve, so it can’t build as much pressure on the discharge side, causing the discharge pressure to drop. So the noticeable symptoms are higher suction pressure and lower discharge pressure.
