Single-acting reciprocating compressor: strokes for suction, compression, and delivery In a single-acting reciprocating air compressor, over how many piston strokes do suction, compression, and delivery occur? Choose the correct option.

Difficulty: Easy

One stroke
Two strokes
Three strokes
Four strokes

Correct Answer: Two strokes

Explanation:

Concept/ApproachIn a single-acting cylinder, suction occurs during one piston stroke (e.g., downward), while compression and delivery occur during the opposite stroke (e.g., upward) as the discharge valve opens once cylinder pressure exceeds delivery pressure.

SequenceStroke 1: Suction.Stroke 2: Compression & Delivery.

Final AnswerTwo strokes
