Which type of cylinder runs until the stop pushbutton is pressed?

• A. Single-cycle cylinder reciprocation circuit
• B. Continuous-cycle cylinder reciprocation circuit
• C. Double-cycle cylinder reciprocation circuit
• D. Intermittent-cycle cylinder control circuit

Answer: (B)

In a cylinder reciprocation circuit, the continuous-cycle setup is designed to keep the cylinder moving through its forward and return strokes automatically. It will keep cycling until you press a stop pushbutton to halt the action. The other modes do not stay in motion indefinitely: a single-cycle circuit completes one full stroke and then stops, a double-cycle circuit runs two cycles per activation, and an intermittent-cycle circuit operates in bursts or on-demand rather than continuously. So, the type that runs until you press the stop button is the continuous-cycle cylinder reciprocation circuit.
